Paul for Model Number PLCF489CCF So far, this site has been extremely helpful. I'm really trying to nail the problem down before springing for a new control panel, since it isn't cheap. I'll try to cut my diagnostics down to the essentials. Similar to other posters, no bake in the big oven. Broil works fine. Tested the baking element and it looks good. Negligible resistance. No voltage across bake element when bake cycle is on. Therefore, suspicious of control panel. I am getting 240V between E7 (bake) and E9 (L1, the black side if I have it correctly). This tells me I have continuity all the way from the Red side, through the relay marked "RELE DLB" on the wiring diagram and up to E7. Am I correct that the relay on the board must be therefore be faulty, because otherwise E7 to E9 voltage would be zero, since the "Bake" relay connects them? Thanks in advance.
Answer Paul, If you are getting no reading at the bake element for power then the issue will either be in the relay or will be in the control board. If you pull one of the terminals off the bake element and check for voltage. Check the loose wire to ground and look for 120 vac and then check from the connected wire to ground for 120 vac. This will determine which side of the system you will need to go to. If it is the side that the relay is on then you will want to access the dbl relay and test on the red wire that comes off the relay for 120 vac. If there is power there but not on the yellow wire with the unit on then the issue will be a faulty relay 903178-9010. If you check at the control board on the E 7 terminal for 120 vac to ground and there is no voltage then it is the control board that is the issue. Read More...
