My Kenmore 790 Electric Range has the code nCAL on the display. What does this mean?
This usually indicates an electronic oven control board failure. It could also indicate a failure of the sensor probe, one of the elements, or the wiring. Try turning off the power for a while, 10 minutes or longer. If the problem persists when power is reapplied and none of the keys respond, you need to unplug the range (or shut off the power at the circuit breaker). Then usually you need to replace the oven control board and overlay. If you post the full model number of your range, I may be able to check for the appropriate replacement part.
I hope this helps. Kenmore appliances with 790 were manufactured by Whirlpool.
