Question and Answers

Q:

Why won't my Kenmore 91140499891 wall oven heat after I just completed an F7 code repair?

A:

I recommend checking both of the breakers for the wall oven. The electronic oven control board will operate if only one of the 120 volt legs of 240 volt power is supplied to the oven. If the second 120 volt leg of power is missing, the oven will not heat.

See if the broil element will heat in the broil mode. If the broil element heats properly, this indicates that proper voltage is supplied to the control board and the broil element. If neither the broil element nor the bake element will heat, then you could have a voltage supply problem. A technician would need to make voltage checks to verify that the range is getting the second leg of 120 volt power.

Electrical power surges and glitches through the electrical lines during a storm can damage the electronic control board in the oven. The control board supplies one of the 120 volt legs of 240 volt power to the bake and broil elements. The first step in troubleshooting a control board that is not operating properly following a storm would be to completely disconnect electrical power by shutting off the breakers for 5 minutes. After resetting the breakers to restore electrical power, see if the range operates properly. If not, then it is possible that the internal circuitry in the control board was damaged by an electrical power surge encountered during the storm. A technician would normally check the voltage going into the control board on the black wires L1A (TAB2) and L1B (K2 Relay) to the neutral (N) white wire on TAB1. The wiring diagram and the control board diagram are shown in the images below. The technician would also check voltage at the oven and broil elements in the bake and broil modes. I do not recommend making these live voltage checks yourself. Contacting live wires while the oven is energized can result in lethal electrical shock.

Using this technical information, the technician should be able to determine the cause of the heating problem in the oven.
