How to Reset a Norcold Control Board

Norcold makes small refrigerators that are commonly found in RVs and boats. When the refrigerator is showing a "No Cooling" error code the unit must be repaired. There could be any number of reasons for the code to appear. When the repair is finished, the last step is to reset a Norcold control board to clear the error. If this is not the first time the error code has occurred, the process to reset a Norcold control board is more involved.

...
The first time the code appears, turn the unit off and on.

Step 1

Turn the refrigerator "off " and unplug the power cable.

Step 2

Pull the unit out to access the back.

Step 3

Disconnect the wires plugged into the power board on the back of the unit in the following order: 12Vdc positive and negative wires, AC power supply cord, the Solenoid gas valve wire and the spark/sense electrode assembly wire. Each wire is labeled. Grab each wire by the plug (not the wire) and pull the plug from the socket in the power board.

Step 4

Remove the four screws in the corners of the power board cover with a Phillips head screwdriver and pull the power board cover off.

Step 5

Plug the following wires back into the power board in the following order: spark/sense electrode assembly wire, Solenoid gas valve wire, AC cable and 12Vdc positive and negative wires.

Step 6

Plug the refrigerator in and turn it "On."

Step 7

Insert one end of a jumper wire into the socket to the right of the white/violet wire on the wire harness (Pin 15) and touch the other end of the wire to one of the bolts mounting the power board to the unit for 10 to 15 seconds or until a "click" is heard. A jumper wire is a length of electrical wire with 1/8-inch of the core exposed at each end.

Step 8

Remove the jumper wire.

Step 9

Turn the refrigerator "Off" and unplug the power cord.

Step 10

Disconnect the wires plugged into the power board in the following order: 12Vdc positive and negative wires, AC power supply cord, the Solenoid gas valve wire and the spark/sense electrode assembly wire.

Step 11

Screw the power board cover back into place.

Step 12

Plug the following wires back into the power board in the following order: spark/sense electrode assembly wire, Solenoid gas valve wire, AC cable and 12Vdc positive and negative wires.

Step 13

Plug the refrigerator in and turn it "On." If there is still an error code, repeat the process until it is cleared.
