Hi
I am having temperature issues with the upper oven only. On display it would say 400 degrees but in actual ot would be far less than that. Maybe off by a 100 degrees. I have replaced temperature sensor already which did not help. Also it does heat up on bake and broil so it's not the heating elements also. I am thinking it may be control board but my oven has multiple control boards in it. I am wondering if it would be the relay board or main control board that might need replacing. Model # is 790.42003605.
THANK YOU.

Here's the part you need. The relay board serves to energize the upper and lower oven heating elements, convection and door lock motors, cooling fan and oven lamp.

This is a relay control board manufactured by Frigidaire to replace a broken or faulty part in wall ovens.In order for the appliance to work as intended, the relay control board needs to be able to receive signals from the main control board. It can then send relays that regulate the oven's...

Hi Rick,
Thanks for your response. I replaced the relay board today and so far it has been working fine. Main issue I was having was that oven would heat to set temp but temperature would fluctuate drastically while oven was working. Anyway thanks for the help.

There was probably a sticky relay on the board.
