Both controls on my oven don't work. They flicker so that the time and temperature are reset every few seconds. Could that be caused by the suppressor, which appears to be the only common electrical component for the two sides?
Answer Hi Ken. I would use the digital capacitor Tester / Volt/ohm meter part # TJMA-DM1. At the terminal block, make sure that there is 240 vac between both outer legs and 120 vac from neutral (middle) terminal and each outer leg. Use double nuts on each terminal stud to keep the terminal wires tight. Look at the suppressor red (or blue) round flat varistors to see if they are cracked or if the board is cracked. Part # 4451985. You have an internal supplied wiring diagram inside the top. Thank You.
There is a humming sound coming from the vicinity of the control panel of my oven. Do you think the control panel needs to be replaced or is the suppressor bad? The control panel works fine although the clock led is on it's way out.
Answer Hello Jrodela. Based on the information you provided, it sounds like the control board 4453661 may be bad on the unit. Remove the control panel from the unit and see if that is where the noise is coming from. If so, you will need to replace the control board. Hope this helps.
