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.
