Oven won't hold temperature, PF code display..
Answer Luis, The "PF" code in the display, is an indication of a voltage drop or outage to the range, You should check and insure the wiring connections at the terminal block are proper and tight. If the voltage to the ERC, drops below 102 VAC or you loose power completely, the "PF" error will be displayed. As for the stove not holding temperature. If the ERC and power supply are OK, the most likely issue would be in the oven temperature sensor or wiring 8053344, Thanks and Good Luck
Range oven won't hold temp anywhere in the mid-temp range. Of course these temps are the most used. Turn the knob up to the higher temp. range and it heats well. I'm guessing I need to replace the control module?
Answer Hi Harry. Remove your power. Remove the door and storage drawer (if equipped). This makes it lighter /easier to slide the unit out. Remove the back. Check your terminal block for proper 240 vac and 120 vac from each Leg to neutral White wire. Unhook the sensor wires and see if it will ohm out between 1080 - 1000 ohms. Rotate the wires while checking to show for opens or shorts. If bad it is part # 8053344. It is responsible of keeping the control aware of heat on and off cycling times. Make sure you ohm out the elements for continuity and not shorted giving partial heat. Broil elmt. part # 9757340. Bake elmt. part # 9758519. If these are good and the connections are tight, then focus at the relays on the clock control. While calling for heat, test to verify 120 vac from the relay outputs. If bad, then clock part # 4453711. Control - Range (white). Electronic Control Board - Color: Black 4453710. Thank You.
