Do ovens have some sort of safety cut or something?

    Hi all,

    Weird one.

    Have a Westinghouse oven here, and it works fine... up to 200 degrees. If you cook in these ranges it functions as normal.

    If you go beyond 200, to 220, 240, 260... it will heat up to that temperature... but as soon as it gets to temp, it stops heating. You put your food in at 240 and even though the oven looks "on", it stops heating so the internal temp gradually falls. No amount of fiddling with the temperature dial or switching it on/off can get it to heat again, until it cools off completely.

    Could this be a safety feature baked into the oven? It's very exact on 200 or over is all. Can't see anything in the manual about it.

    This is a modern townhouse, wouldn't surprise me at all if the oven is doing this because of a shit install. The rest of the place is built like a joke.

    Thanks.

    It’s like something gets too hot and has to cool right down to reset. Aren’t they single hardwired so it has to be an internal fault?

    Does the oven have a brand?

    there's likely a thermal cutoff for safety reasons so that it doesn't burn your house down. Possibly it's faulty and is tripping at a lower temp.

    The temperature cut that's occurring may not be part of the bake zone. The ventilated area around the oven body may have a thermoswitch at a lower temperature, say 80 degrees C. Meaning that if the area in the outer shell becomes too hot - perhaps due to a faulty ventilator - it would also cut out.

    ED- although if it's exactly 200 measured in the oven, that does sound too exact for it to be a switch on the body. Or perhaps it's just co-incidental.

    Hmm. I might pull it out of the wall and see what it looks like back there and compare the enclosure space to what the manufacturer calls for...

    It’s a Westinghouse WVE616.

    Brand new and acting up from the get-go, or was working fine for <insert period of time here> and it's now saving you electricity?

    Could be wrong, but sounds more like either the temperature adjustment thermostat knobby thingy is borked or the actual temperature probe inside the oven is borked.

    It's not something silly like someone's programmed it (or it's become sentient and just doesn't like you...) to do a silly thing like that? Time for some RTFM perhaps?...

    Yes ovens have a thermal cutout that opens the circuit inside the oven when the threshold is reached.

    This can occur if the cooling blower fan is not working as intended.

    What are you cooking at 200+ deg?

    Being here on Overclockers, it'd better be reflowing a few circuit boards... :D

    It has always done it. I didn't buy or install this oven however, it came with the townhouse. Been about a year.

    It doesn't seem to have any program options as far as that goes. It does have a timer that turns the oven off once it reaches the time limit, but that turns the entire oven off, the light, fan, everything, whereas when the oven stop heating, it's still got the light on inside and fan whirring.

    You can hear the cooling fan but perhaps it's not working to efficiency.

    To cook Pizzas properly you crank (domestic) ovens to as high as they will go, as real pizza ovens are ~350C

    The daily baguette is cooked at 240 or so

    You cook roasts at 180 then blast them with 250 to finish off to brown the skin nicely

    etc etc

    If a year since new, then ponder fighting for a warranty claim if it's actually borked perhaps? Unfortunately first thing they'll say is "Give us your credit card details and we'll send a man around"...

    Could be a bad install, would still think it's either borked control hardware or software/programming. Durr, Today's Dumb Statement I know...

    Dumb Question though - contacted Westinghouse yet?

    Place was built in 2014 so it's well out of warranty! Contacted the owner of the place and have told them many times to come fix it, excuses excuses and the virus has been the ultimate excuse as far as them unable to have someone come and look at it. Will definitely not be renewing the lease (looking to buy anyway) but until July I want an oven that cooks properly!

    Its the blower fan, not the actual fan inside the oven.

    Yes, I don't use a fan forced oven. I know it's not that fan.

    Aaaaah, so it's in a rental then - Been There, Had That (air con died in 43 degree 80% humidity Qld summer...).

    Still worth a call to Westinghouse in case they can offer a sane fix over the phone with a short tap from a hammer without costing you anything. Unlikely, but you never never know...

    And def worth a call to Tenants Association to determine your legal options and/or lodge a complaint against the Owner.

    Or if you're looking to buy and are damned 1000% certain of being able to do it, as under the current virus thing about "Tenants Can't Be Evicted" then tell the Owner either it gets fixed pronto or your rent payments will suddenly have problems - hell, I would.

    But obviously get real legal advice first... ;)

    Wait, people use ovens on settings other than 180?

    Portable smart ovens get hotter than that, time to consider one instead of dealing with realestate/landlord run arounds.

    Wedges, chips, pizzas, browning roasts, nachos.

    I would be fucking lost if my oven didn't go over 180.
