I have a whirlpool self cleaning oven model # RF365PXMW0, the bottom element wont get real hot, the timer starts to count down from 6 minutes when you try to start the oven. When you turn on broil it starts to get hot then shuts down. I tried different settings and nothing seems to work, the elements were tested and they are fine, The repairman I used is not qualified yet he told me it was the control board, is the oven worth replacing the board?, I already bought a new board ($156) but now I am having my doubts about replacing it because he told me it was very risky. Should I roll the dice and replace it, or could it be something else.The oven looks like new although I do not know how old it is?

p.s. he confessed that he has never replaced one, yet the sign outside his home says appliance repair. This oven is in a rental unit.

We had a real electrician hook up 220 when we bought the place, because it use to be gas.

Let me try to explain better? I have a whirlpool self cleaning electric oven model # RF365PXMW0. When I push the bake button on the electronic key pad the timer starts to count down from 6:00 in seconds, when it reaches 0 nothing happens. When I push the broil button it heats up and then cools down. The temperature reading never shows on the electronic display. No preheat, no nothing, just the timer which always starts at 6 minutes and counts down to zero. The stove top works fine. I had a licensed electrician convert the hookup to 220 and the oven worked fine for the previous tenant. The new tenant used the self clean option and it hasn't worked properly since. Could it be the control board like my UNQUALIFIED repairman said or could it be something else?

No, when i press bake AND start the timer starts. no temp no nothing. timer counts down then returns to time.
I should be able to set temp after bake , but I can't.

thanks I,ll keep that in mind
