Purchased a used GE Monogram Advantium wall speedcook oven mod #ZSC2000FBB01. Seemed to be working fine except the clock kept changing time after cooking. When we stopped a speed cook cycle before it was completed, leaving the door open to clean the oven display went blank and the interior lights went out.
Reseting the circuit breakers in the panel caused the oven display to light up display set time and go out again before I could set the clock. All the while it was getting power it made a humming sound. Tried this 3 times before shutting the power off for a day.
Checked the power connections and turned the breakers back on, oven lit and made humming noise. Was able to set clock and run a mcrowave cycle. Stopping the cycle by hitting the clear button made the humming stop and the display remains on. Any Ideas???
UPDATE:
The oven remains on but will not continue on Speed Cook if door is opened to "Turn Food Over". Clock then changes time. Tried manual cook and it seems to work ok…OR SO WE THOUGHT ! After cooking dinner the oven went blank. It would not respond to any input not show any display or lights. Tried resetting the breakers again to no avail. Left breaker off overnight. Turned them on in morning now oven has power ??? There is voltage to the junction box where oven is connected.
