Re: Refrigerator not working on electric
In checking the service manual for that model refrigerator there are these suggestions.
Since the 3A fuse is for the 12V power and it must have that to operate on either gas or 120V, that has to be good. The 5A fuse is for the 120V power to the heating element and can be checked by measuring across the two terminals that supply the power to the heater, when 120V is selected and the refrigerator is calling for cooling. To check, turn the temp. to it's lowest setting just before you check for power.
The modular connecters must be properly seated on both the eyebrow board and the control circuit board. Make sure that the 120V power supply is good to the power plug, and at the circuit board. You must have 120v on pins J7 & J8 of the power supply board. If it is not there, but the other things are good, replace the power supply. If it is there check the resistance of the heater (about 40 to 45 ohms) and the resistance from each heater lead to ground (near infinity). If the resistance values are not proper, replace the heating element.
