Kenmore Pro 790.42003605 Double Oven Preheat

[borgunit]

Been battling this since I have had the oven.

When preheating, the oven kicks off all the time.

If you keep starting over, it eventually"sticks" and starts to preheat. It has been very annoying.

I have replaced boards 316443910, 318601500, and both temperature sensors. No change.

 

Any suggestions? Thanks.

Need to monitor power while it does this to see if it’s the relay on the board or your source of power.

But since you’ve changed boards I’d wonder about power source...  Are we positive outlet is wired correctly and power cord connected to stove correctly?

Any error codes?

Possibly cooling fan

Finally got it I believe. 

Was circuit board "Frigidaire 316460901"

Warms up and has not errored in two weeks (a new record).

Wow.
