Oven repair gone bad

[Jimberlin]

I am in Germany but I think the same repair principles will also work on appliances here. I have a built-in countertop oven with a ceramic glass countertop stove top. The bottom heating element for the oven failed. I bought a new part and replaced it. After I repaired it the controls of the oven and burners do not work properly. In order to get the burners to turn on I have to have the oven on, otherwise there is no power to the burners. It also appears that the oven heat is not regulating properly. When I turn in on to the very lowest setting (in order to operate the stove top burners) it seems that the oven becomes VERY hot, much more than the temperature setting.  I re-checked all the connections and they are exactly the way they should be. I'm at a loose for what to do. Any ideas? ONE MORE THOUGHT. When I was repairing the oven I found a silver unprotected wire wrapping around the rear panel of the oven and returning back inside. The only way to get the rear cover off was to cut that wire. I thought is was simply some kind of securing wire to hold the back on. Could it be a wire to a temperature controller or thermostat? If so, could that wire be soldered back and function properly? At the moment I only wrapped it together. Thx!

I think I know now what the problem is. I cut the thermostat wire and now need to replace it.

Yep, you cut the thermostat capillary tube. You can not re-attach it, and the thermostat will need to be replaced. But this would not cause the burners not to work. You have a second condition- most likey power related. The burners and the oven are generally independant of each other and, in fact, should work seperately. If you have to turn on one for the other to work, it sounds like one is drawing power from the other, which sounds like a loss of voltage issue or improper neutral or ground.

Did you have to unattach the power cord? If so, revisit that to be sure it is wired correctly.

I have seen this too, this in some of the Frigidaire built side by side ovens- the neutral can become a back circuit when turning on the thermostat in the one side will allow function in the other...

I have never faced such situation.
