Help! My New Year's Day diner is in jeopardy...
I have a Frigidaire oven (Model: FEC55EB-1) that is acting up strangely as
of late. On this model, a selector knob allows for the use of the bottom
(bake) or top (broil) element and a separate knob controls the temperature.
When using the bake element, all is fine and the oven keeps precise
temperature. When using the broil element, if it is set at, let say, 450F,
the element kicks in and becomes red and the temperature starts to rise.
Then, at about 350F, the element stops working and the temperature stops
rising. You can wait all you want, the temperature will start to slowly
decrease and the element will not work again. The heating led does stay on.
If you slowly turn down the temperature knob, it will reach a point where
the heating led goes off; I believe that would be the temperature of the
oven at that point. Pushing the knob at higher temperature, or even all the
way up, will not start the broil element again, but, opening the door for a
while will. If you shut down the oven and start the broil element at 450F
again, the behaviour is the same (it will work for a while and then stop
before reaching the set temperature). If you switch to the bake element at
any time, the oven works perfectly and keeps its temperature.
I'm a bit puzzled because I can see the broil element is not shorted and
becomes red hot when it starts. Also, the temperature probe and control
seem to work fine since the bake element can keep the temperature constant.
I was told it could be the door not closing well. I can see the seal might
not be in perfect, but wouldn't that make the oven heat constantly?
I wouldn't mind opening the unit and testing stuff, I'm just wondering
where would be a good place to start?
