Mike for Model Number gleb3ot8cba Came home from work today and found the oven light wouldn't go off. Checked the door switches and found the bottom door switch was shorting out and hot. The plastic post had melted. When I pulled on the post, the switch broke and apparently one of the wires came loose and touched the metal frame of the oven and began arcing. After a few seconds the arcing stopped and I saw a small fire inside the walls of the oven. The insulation had caught on fire. I extinguished the fire and had my son kill the breaker. After retrieving the 3 wires that went to the switch and isolating them with electrical tape to prevent accidental contact, I re-energized the breaker and found that there were no lights on the control panel. I removed the oven and began to disassemble the back of the oven to inspect the potential cause of the loss of control lights. I noticed a circuit board that went to the control panel and two relay boards. I am assuming the problem with is with one of those three items. Any suggestions on how to check which one it is, if any?? Thanks
Answer Hello Mike. You will need to test for power coming into the relay boards 318022001 318022002 and going to the control board 318010501. If there is power at the control board, and it does not light up, you will need to replace the control board. Anytime there is a short to ground like that, it can cause all 3 board to be bad in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
