Matt for Model Number FEF336ECE Hello, I'm also having an issue with my range. Judging by other questions already answered, I may need this control board, but my volt meter test doesn't seem to think this is the issue? Currently the stove top works, but the oven won't heat up when trying to bake or broil. The 240 volt line is fine, checked it at the plug. I can hear the relays clicking on/off while the unit is turned on, but still no heat. Using a volt meter, I have power going to the "Bake" terminal listed on the control board, but it seems like it's 120 volts. There is also power at the wires connected to the elements, also 120 volts. Checked the elements using the volt meter and they test to be fine/working. Does all of this still sound like the issue is with item # AP3956392? Should it be replaced or something else?
Answer Hello Matt, The test procedure that is the easiest to determine the component at fault is rather dangerous, but works great. The way I do it is unplug the unit and open the control panel so I can access the wiring to the control. Find the one for bake. Unplug this wire and set it so it cannot touch anything. Now you have to test to this wire also with your test meter without touching it and getting shocked so try to lay it so it is against the wiring harness. I like to use a wire tie or electrical tape to secure it so it cannot drop and contact ground or another wire and cause damage to the harness. Now you're ready to begin. Plug the unit in and set the control to bake. Using the units' chassis as the test reference point, look for the 120Vac on the wire you disconnected and on the terminal you disconnected it from. Once you have determined which has no voltage, unplug the unit. Now for the explanation. If the bake terminal has no voltage on it during the test, the relay on the board is not passing the second leg of voltage. If the wire you disconnected from the terminal is the one with no voltage, the bake element has failed or there is a thermal fuse in the circuit that has opened. You see, the bake element has 120Vac riding on it at all times the power is supplied to the unit. The only time voltage is on the bake terminal is when the control energizes the relay and the relay passes the second 120V leg. When you test the unit with the wires hooked up, there is no way to tell whether you lost L1 or L2. This makes the repair very difficult. By removing the wire, you know which leg you have lost and you can use this information to pinpoint the issue. Read More... Answered by AppliancePartsPros.com | Friday, August 24, 2012
