I-oveni yokufudumeza i-arcing, ukuzicoca umsi womjikelo, kunye nocango lwe-oveni olutshixiweyo¶

Iimeko ezingxamisekileyo ezimbini ezoyikisayo ze-oveni zibamba abanikazi bezindlu bengalindelanga yonke imihla: ibhaki yombane okanye into yokufudumeza ngesiquphe ngequbuliso amadyungudyungu, iintanda, kwaye igqabhuke ibe yintsipho yombane emhlophe-orenji emfamekileyo efana netotshi yewelding ephantsi kwamanzi okanye ukudangala kwendlela, kunye **nobushushu obuphezulu bepyrolytic umjikelo wokuzicoca / 50000 degrees celsius * 5000 ukuya 3000 ℃ (4000 degrees Celsius). Fahrenheit) elayita igrisi enzima ngaphakathi kumngxuma ngelixa itshixa ngomatshini ucango lwe-oveni luvale. Kuzo zombini iimeko ezingxamisekileyo, ukuvula ucango lwe-oveni okanye ukwenza intshukumo engalunganga kunokubangela igrisi eqhumayo i-flashover (backdraft) okanye ikuveze kwi-240-volt yombane ebulalayo.

Xa i-oven yombane yokufudumeza i-arcs, ukucinezela ngokulula ** "Rhoxisa / Vala"** kwi-touchpad yolawulo lwangaphambili ayisoloko imisa ukuvutha, kuba ukuba ucingo lwe-nichrome olutshisiweyo lwangaphakathi luye lwadibanisa kwi-sheath yesinyithi esekelwe ngaphandle okanye ukuba ibhodi yokulawula ibhodi yokulawula i-welded ivaliwe, i-120 ukuya kwi-240 volts yombane iyaqhubeka nokuhamba ngokuthe ngqo kwi-opole. ibreaker** ngaphakathi kwephaneli yombane engundoqo yekhaya lakho. Ngokufanayo, ukuba i-oven ibamba umlilo okanye ikhuphe umsi omnyama ngexesha lokuzicoca, ukugcina umnyango uvaliwe kwaye usika amandla kwi-breaker yindlala yomlilo we-oksijini kwaye ivumela i-lock yangaphakathi ye-thermal ukuba ikhulule ngokuzenzekelayo xa i-cavity ipholile ngaphantsi kwe-260 ukuya kwi-315 degrees Celsius (500 ukuya kuma-600 degrees Fahrenheit).

Yenza oku ngoku¶

1. UNGAZE uvule ucango lwe-oveni ukuba ubona amadangatye, iintlantsi zombane ezimfamekisayo, okanye umsi ongqindilili omnyama/omdaka ngaphakathi: Ukugcina ucango lwe-oveni olunzima nolugqunyiweyo luvaliwe luqulathe amaqondo obushushu angama-500-degree-Celsius (930-degree-Fahrenheit) ngaphakathi kwentsimbi yomlilo kwaye uyalamba amadangatye egrisi oksijini. Ukutsala ucango luvuleke kwazisa ukungxama kweoksijini yegumbi elitsha ngequbuliso ebangela ukuba umphunga wegrisi oshushu kakhulu uqhume uphumele ngaphandle ebusweni bakho nakwiikhabhathi zasekhitshini (** uqhushumbo lomsi / flashover **).
2. Yiya ngqo kwiphaneli yombane yendlu yakho engundoqo kwaye ujike i-240V "iRange / I-oveni" isiqhekeza esiphindwe kabini ukuze IVALIWE: Sukuxhomekeka kuphela kwiqhosha elingaphambili le-oveni okanye kwiqhosha lepad yokuchukumisa xa into yokufudumeza ijikeleza njengeblowtorch. Hamba uye kwibhokisi yakho ye-breaker yombane kwaye flip enkulu ** 40-amp okanye 50-amp double-pole Range / Wall Oven breaker ** ngokupheleleyo ukuba ** OFF ** ukubulala onke amandla ombane ngoko nangoko. (Ukuba yi-oveni yerhasi, cofa u-Rhoxisa/Cima kwaye uvule ivalve yokucima igesi ebhalwe ngesandla ngasemva koluhlu ukuba iyafikeleleka ngaphandle kokufikelela kumadangatye, okanye ushiye ucango luvaliwe kwaye ubize isebe lomlilo).
3. Ungakhe uzame ukuvula ucango lwe-oveni olutshixiweyo oluziCwangcisileyo nge-crowbar, isikrudrayiva, okanye amandla: Ngexesha lokuzicoca, intsimbi enenjini kunye nesitshixo se-bi-metallic thermal sikhusela ucango nanini na amaqondo obushushu angaphakathi adlula **260 ukuya kuma-315 degrees celcius (500 ukuya kuma-600 degrees Fahrenheit)*. Ukunyanzelisa i-latch kukrazula intonga yangaphakathi yokutshixa ngokusisigxina, kuqhekeze ifestile yeglasi epholileyo, kwaye kukhuphe ibhola yomlilo yomsi wegrisi ovuthayo.
4. **Phuma iintaka ezifuywayo ngokukhawuleza kwaye uvule iifestile ukuze ukhuphe umoya we-carbon monoxide kunye nomsi we-pyrolysis *: Imijikelezo yokucoca ngobushushu obuphezulu ikhupha okubalulekileyo i-carbon monoxide (\(\text{CO}\)), i-acrolein, kunye ne-PTFE/i-fluoropolymer fumes ukusuka kwi-oven liners okanye i-enamel coatings kwi-100 yeentaka ezinobungozi kunye ne-asthma ye-100 ekhulwini. iintsana, kunye nabantu abakhulelweyo.
5. ** Fowunela u-911/112/999 ngoko nangoko ukuba amadangatye okanye umsi uyatyhala ujikeleze i-oven door gasket, emva kwesitovu, okanye kwiikhabhathi eziphezulu**: Ukuba umlilo awubonakali ufi phantsi ngaphakathi kwebhokisi etywiniweyo ngaphakathi kwemizuzu emi-2 ukuya kwe-3 emva kokukhubekisa isaphuli sesekethe, okanye ukuba kuthululwa umsi ovela ngasemva, kwaye biza i-9 kwinombolo engxamisekileyo emva kwefowuni yakho. I-US kunye neCanada, i-112 kwi-EU, i-999 e-UK; amanani kaxakeka).
6. Vumela i-oveni yokutshaya eyazicocayo okanye into yokufudumeza nge-arced ukuba iphole ngokupheleleyo kangangemizuzu engama-60 ukuya kwengama-90 phambi kokuvula ucango: Nje ukuba isaphuli-mthetho sicinyiwe (okanye ucinezele uCima/Cima kumjikelo wokuzicoca), kuthatha imizuzu engama-30 ukuya kwengama-90 ukuba iqondo lobushushu le-oveni lehle ngaphantsi kwe-260 °C livuleke ngokuzenzekelayo ucango lwe-motor.

Icandelo loku-1: I-oven yombane yokufudumeza i-arcing kunye nokusilela kwe-blowtorch¶

Zimbalwa iintsilelo zezixhobo zekhaya ezibonakala zinobundlobongela kune-oveni ye-oveni yombane ye-tubula okanye i-broil element engaphumeleli ekubhakeni. Ngaphandle kwesilumkiso, kugqabhuka intlantsi eluhlaza okwesibhakabhaka okanye eorenji eqaqambileyo kwelinye icandelo lentsimbi emnyama yokufudumeza intonga, ehamba kunye nesandi esikhulu sombane, umlozi, okanye ukugquma. Kwimizuzwana eyi-10 ukuya kwengama-60, indawo ivutha njengeflare yendlela ye-magnesium okanye itotshi ye-oxy-acetylene ye-welding njengoko inyibilika kwicandelo le-2-centimeter yetyhubhu yentsimbi ngaphambi kokuba ekugqibeleni itshise isithuba esibanzi ngokwaneleyo ukuphula isekethe.

Kutheni izinto ze-oven yombane ngokukhawuleza zi-arc kwaye zinyibilika njenge-blowtorch¶

Yonke into ye-oven etyhubhu yombane (ehlala ibizwa ngokuba yi Calrod element) iqulathe iileya eziconcentric ezintathu:

1. I-Centre Core: I-coiled nichrome (nickel-chromium) ucingo lokumelana oluthwala 240 volts AC (izoba i-2,000 ukuya kwi-4,000 watts) kwaye ikhanya ngokubomvu-kushushu ngaphakathi.
2. I-Insulating Layer: Ipakishwe ngokuqinileyo i-magnesium oxide (\(\text{MgO}\)) umgubo weceramic ojikeleze ucingo olujijekileyo, olukhupha ubushushu ngaphandle ngelixa lukhusela ngombane ucingo oluphilayo lwe-240-volt olusuka kumbhobho ongaphandle.
3. I-Outer Metal Sheath: Intsimbi eqinileyo esekiweyo okanye ityhubhu ye-Incoloy alloy yangaphandle oyibona ngaphakathi kwi-oveni.

Kwiminyaka emininzi yokufudumeza kunye nokupholisa imijikelo, okanye xa ukutya okune-acidic kuchithwa (i-tomato sauce, ukuzaliswa kwe-pie yeziqhamo, ityuwa, okanye i-marinades eneswekile) ithontsiza kwi-element kwaye igxobhoze isinyithi, okanye i-foil ye-aluminium ibekwe ngokuthe ngqo kwi-rack ephantsi, i-hairline crack okanye i-blister ikhula kwi-sheath yentsimbi yangaphandle. Nje ukuba ukufuma okanye umoya ungene ekuqhekekeni, okanye ikhoyili ye-nichrome yangaphakathi iyanda kwaye ichukumise i-sheath yentsimbi yangaphandle, i-dead short-to-ground (240V/120V arc fault)* yenzeka. I-arc yombane enesiphumo ifikelela kumaqondo obushushu angaphezu kwama-*2,500 degrees celcius (4,500 degrees Fahrenheit)**, inyakamisa ngoko nangoko isingxobo sentsimbi esingenasici sibe yimvula yeentlantsi ezinyibilikisiweyo.

Kutheni ucinezela u-"Cima / Rhoxisa" esitovini ngamanye amaxesha AYIKUYIMI into yokurhweba¶

Kwiindawo ezininzi zombane zanamhlanje ezingama-240-volt kuMntla Merika kunye nee-oveni eludongeni, into yokufudumeza yondliwa yimilenze emibini eshushu ye-120-volt.L1 kwaye L2). Ukugcina iindleko zokuvelisa, ezininzi iibhodi zokulawula i-oven ye-elektroniki zitshintsha kuphela ** enye ** yemilenze emibini ye-120-volt (L2) usebenzisa isidluliseli xa ucinezela Rhoxisa/Cima, ushiya omnye umlenze we-120-volt (L1) inikwe amandla ngokusisigxina ukuba nje isitovu sifakiwe.

• Ngethuba lokusebenza okuqhelekileyo, ukuvula umlenze omnye kumisa ukuhamba kwangoku kwikhoyili.
• Nangona kunjalo, xa i-element blister kunye nebhulukhwe emfutshane ngokuthe ngqo kwiqokobhe layo lesinyithi elisekelwe phezu komhlaba, umbane uhamba usuka kubomi ngokusisigxina. L1 umlenze othe ngqo kwi-chassis yentsimbi esezantsi, okuthetha ukuthi ** into inokuqhubeka i-arcing kwaye ivutha nasemva kokuba ucinezele u-"Rhoxisa / Vala" kwiphaneli ye-oveni **, okanye ukuba utyando ludityanisile abafowunelwa bebhodi yokulawula bavale.
• Ekuphela kwe-100% eqinisekisiweyo yendlela yokumisa i-oven e-arcing ngoko nangoko kukuflip i-240-volt Range/Oven circuit breaker UKUVALA kwiphaneli yombane yekhaya lakho.

Icandelo 2: Ukuzicoca Umsi we-oveni, imililo, kunye neemeko ezingxamisekileyo zocango olutshixwayo¶

I-Pyrolytic i-oveni ezizicocayo zisebenza ngokutshixa ucango lwe-oveni kunye nokufudumeza umngxuma wangaphakathi ukuya kumaqondo obushushu agqithisileyo, phakathi kwe-425 kunye ne-500 degrees Celsius (800 kunye ne-930 degrees Fahrenheit)* ngeeyure ezi-2 ukuya kwezi-5, ukuze kutshiswe ukutya okubhakiweyo kunye nokuthambisa kwimfumba encinci emhlophe. Kuba amaqondo obushushu okutshisa okuzenzekelayo kweoli eninzi yokupheka, amafutha ezilwanyana, kunye nebhotolo iphakathi340 kunye ne-425 degrees celcius (644 kunye ne-797 degrees Fahrenheit), nawuphi na umaleko oshinyeneyo wegrisi yebhekoni elityelweyo, ipani evuzayo ethontsizayo, okanye i-oven engasemva ekhohlo okanye iliner ngaphakathi kwe-oveni iya kuzigqabhuza ngokuzigqabhuzayo* **

Kutheni UNGAZE unyanzele ukuba uvule ucango lwe-oveni etshixwayo xa uzicima umlilo¶

Xa abaninimzi bebona amadangatye a-orenji evutha emva kwefestile ye-oveni okanye umsi omnyama ophuma kwisitovu esingaphezulu kwesitshisi ngasemva ngexesha lomjikelo wokuzicoca, ithuku labo kukutsala umqheba wocango lwe-oveni, kwaye xa befumanisa ucango lutshixiwe, babambe isikrudrayiva okanye i-pry bar ukunyanzela isitshixo sivuleke ukuze bakwazi ukutshiza umlilo ngesoda yokubhaka okanye ngesoda yokubhaka. Ukwenza oko ngunobangela #1 wentlekele yomlilo wasekhitshini kunye nokutsha okumandundu kobuso ngexesha lokuzicoca:

1. Ibhokisi ye-Oveni Yenziwe Ubunjineli njengeVault yoMlilo: I-oveni yokucoca ngokwayo evaliweyo ine-insulation ye-fiberglass eneendonga eziphindwe kabini kunye ne-braided fiberglass heat gasket ejikeleze umnyango eyilelwe ukuqulatha ama-500 ° C (930 ° F) ngokukhuselekileyo ngaphakathi kwibhokisi yentsimbi. Ngelixa ucango luhlala lutshixiwe kwaye lutywinwe, igrisi evuthayo idla ngokukhawuleza ioksijini enyiniweyo ngaphakathi kumngxunya omncinci kwaye iziqhumisele kwi-char evuthayo.
2. I-Backdraft / i-Flashover Explosion Risk: Ngaphakathi kwe-oven eyi-480°C (900°F) etywiniweyo, imiphunga yegrisi eshinyeneyo engatshiyo ifudunyezwa ngaphezu kwendawo yokuzitshisa, ilinde ioksijini kuphela. Ukuba ukwazile ukuvula ucango lwavuleka, ukungena komoya wegumbi ngesiquphe kuxubana nomphunga wamafutha oshushu kakhulu kwaye kubangele kwangoko ibhola yomlilo yeflashover edubula i-1 ukuya kwi-2 yeemitha (3 ukuya ku-6 iinyawo) ngaphandle kocango lwe-oveni ebusweni bakho, iimpahla, kunye neekhabhathi zasekhitshini ezingaphezulu.
3. Umonakalo osisigxina kwiNdibano yeLatch: Ukunyanzeliswa kwesibane socango olunenjini kugoba intonga yangaphakathi yecam yentsimbi kwaye kwaphule iiswitshi ezincinci kwinjini yelatshi, ishiya ioveni yakho ibambekile ngokusisigxina. F9 / F5 / Door Lock Error chaza ukuba kubiza amakhulu eedola ukulungisa.

Inyathelo ngenyathelo: Ungawuvula njani umnyango we-oveni obambekayo ngokukhuselekileyo EMVA kokuba i-oveni ibanda¶

Emva kokuba ucime umjikelezo wokuzicoca (okanye ukhube i-breaker ngexesha lesiganeko somsi) kwaye ulinde ** 60 ukuya kwimizuzu engama-90 ** de iglasi yangaphambili kunye nefreyimu yensimbi ye-oven ** ipholile ngokupheleleyo kwi-touch **, isitshixo somnyango kufuneka sikhulule ngokuzenzekelayo. Ukuba i-oveni ibanda ngamatye kwaye ucango lusatshixiwe luvaliwe, landela la manyathelo ama-4 okulungisa ingxaki ngendlela:

Inyathelo 1: Coca umjikelo wolawulo lwe-elektroniki¶

Kwii-whirlpool ezininzi, i-GE, i-Frigidaire, i-Bosch, i-Samsung, kunye nee-oveni ze-LG, ukuba umbane ulayishiwe okanye i-breaker yacinywa ngelixa i-latch ikwimo etshixiweyo, ikhompyutha ilinda umyalelo ocacileyo wokurhoxisa xa amandla ebuyiselwe. - Qinisekisa ukuba i-oven breaker i-ON*, cinezela Rhoxisa / Vala (okanye ubambe Cima/Cima imizuzwana emi-3 ukuya kwemi-5 apho kuboniswe ngumfanekiso wepadlock encinci kwi-touchpad), kwaye umamele ngokufutshane ngesandi esizolileyo imizuzwana emi-4 evuthuza isandi semotor elandelwa yintsimbi cofa njengoko ikhonkco le-latch lirhoxa.

Inyathelo lesi-2: Yenza i-5-minute ye-Hard Power Reset kwi-Breaker¶

Ukuba ibhodi yokulawula i-microprocessor ingumkhenkce ngenxa yobushushu okanye ukunyuka kombane: - Yiya kwiphaneli yakho yebreaker yombane kwaye ujike i- **Uluhlu / i-Oven circuit breaker OFF **. - Lindela ngokupheleleyo ** imizuzu emi-5 ** (ukuvumela zonke ii-capacitors kwibhodi yokulawula i-electronic ukuba ikhuphe ngokupheleleyo). - Flip ibreaker ngasemva ON. Kwii-oveni ezininzi zale mihla, ukuzivavanya kwe-boot kujikelezisa ngokuzenzekelayo isivalo socango olunemoto sibuyele kwindawo engatshixwanga yasekhaya ngaphakathi kwemizuzwana engama-30 yokubuyiselwa kwamandla.

Inyathelo lesi-3: Qala umjikelo omtsha wokuZicoca kangangemizuzwana engama-60, emva koko ucinezele u-Rhoxisa¶

Ukuba i-latch cam enenjini iye yamisa phakathi ngaphandle kongqamaniso: - Qala umjikelo omtsha othi UkuZicoca kwaye uvumele i-latch motor ijikelezise imizuzwana engama-60 de LOCKED ukukhanya kukhanyisa ngokuqinileyo (musa ukuvumela i-oven ishushu). - Cofa u-Rhoxisa / Vala ngoko nangoko. Linda imizuzu emi-2 ukuya kwemi-5 ukuze injini igqibezele ukujikeleziswa kwayo okungasemva.

Inyathelo lesi-4: Ukukhutshwa koomatshini ngesandla (Kwioveni ezibandayo ezinenjini engaphumeleliyo okanye ifuse eshushu)¶

Ukuba umjikelo wokuzicoca wavuthela i-oven ye- high-limit thermal fuse / thermostat ngasemva kwecango (ukusilela okuqhelekileyo okushiya umboniso ufile ngokupheleleyo okanye uthintele i-latch motor ekusebenzeni): - Flip the Range / Oven circuit breaker to OFF. - Khanyisa isibane esiqaqambileyo kwisikhewu esithe tye esimxinwa phakathi kwe phezulu embindini wocango lwe-oveni kunye nomlebe osezantsi wephaneli yolawulo ephezulu (okanye uphakamise i-porcelain cooktop enehenjisi kancinane kuluhlu oludala oluzimeleyo). - Khangela intsimbi encinci egobileyo ** hook ye-latch ** ubambe i-slot yoxande kumphezulu wocango lwe-oveni. - Shelelisela ihanger yocingo oluqinileyo lwedyasi egotywe kwi hook encinci (okanye imela ebhityileyo ye putty) kwisithuba, tyhala ngobunono i hook ye hook elayishiweyo okanye enenjini 1.5 iisentimitha (0.5 intshi) ukuya ekhohlo okanye ekunene (kuxhomekeke kwindlela ihuku ejongene ngayo), kwaye tsala ucango lwe-oven luvuleke.

Icandelo 3: Uyibuyisela njani ngokukhuselekileyo into yokubhaka i-oveni yombane etshileyo ngokwakho¶

Ukuba i-oven yakho yombane iyabhaka i-arced, blistered, okanye inqunyulwe kubini, kwaye ayizange itshise i-wire harness yangasemva, ukubuyisela ielementi yenye yezona zinto zilula, zikhuselekileyo zokulungiswa kwekhaya kwemizuzu eli-15, ukuba ulandela imithetho engqongqo yokuvala umbane:

1. **Flip the 240V Range / Oven circuit breaker to OFF kwaye uqinisekise nge-non-contact voltage tester **: Ungaze uthembele kwi-knob ye-oven. Cima i-breaker-pole-pole breaker kwiphaneli ephambili kwaye uqinisekise ukuba i-oven display kunye nokukhanya kwangaphakathi kufile ngokupheleleyo.
2. Susa iiracks ze-oveni kwaye ukhulule izikrufu ezi-2 zesibiyeli: Nje ukuba into eyonakeleyo ibanda kakhulu, khanyisa isibane kudonga olungasemva lwe-oveni apho imilenze yomibini yento ingena kudonga olungasemva. Susa ezimbini **ikota-intshi (6 mm) hex intloko okanye Phillips izikrufu ** ubambe ipleyiti yokuxhoma yesiqalelo kudonga olungasemva.
3. Tsalela isiqalelo ngobunono phambi kweesentimitha ezi-5 ukuya kwezi-8 (ii-intshi ezi-2 ukuya kwezi-3) kwaye uteyiphe iingcingo ukuze zingatyibiliki ngaphakathi eludongeni:
4. Gently pull the element straight forward until the two insulated wires attached to its rear spade terminals come into view through the holes in the back wall.
5. CRITICAL PRO TIP: Before pulling the spade connector clips off the old element, clamp a pair of locking pliers (Vise-Grips), a clothespin, or a piece of painter's tape onto each wire outside the hole. The fiberglass insulation behind the oven wall pulls backward like a spring; if you let go of an unclipped wire and it snaps back inside the tiny hole in the rear oven wall, you will have to pull the entire heavy stove out from the wall and remove the back sheet-metal panel to fish the wire back out.
6. Inspect the metal wire connectors: If the metal female spade terminal on the end of the oven wire is shiny and tight, slip it firmly onto the new replacement element's male prong. If the wire connector was burned, blackened, or loose from the electrical arc, cut back the burned tip and crimp on a high-temperature nickel-plated steel spade terminal (never use standard plastic-insulated automotive crimp connectors or electrical tape inside an oven wall, as they will melt and catch fire at 230°C / 450°F).
7. Screw the new element in place and turn the breaker back ON: Push the terminals gently back into the rear holes, secure the two mounting screws, slide the racks back in, and restore power at the breaker. Note that a brand-new heating element will emit a faint, harmless factory oil smell and a wisp of smoke during its first 10 minutes of heating as the protective manufacturing coating burns off.
