Hello,

It may be a heating element opening up after running for a while.

Check for 120 volts where the heater plugs in to the control board when the fault occurs. This will let you know if the control board is working or the heater is defective. If 120 volts is not present, try resetting the control board as follows.

Refrigerator Service Manual www.norcold.com/cda N6XX/N8XX Models 21

n/no co Fault Code - No cooling detected by the controls

Power Board Resetting Procedure

1. Turn OFF the refrigerator.

2. Disconnect the following from power board:

a. 12 Vdc positive and negative wires.

b. AC power cord.

c. Solenoid gas valve wires.

d. Spark/sense electrode assembly wires.

3. Remove the power board cover.

4. Reconnect 12 Vdc positive and negative wire.

5. Turn ON the refrigerator.

6. Locate Pin 15 on 16 pin connector (P1). Pin 15 is

the empty socket to the right of the white/violet

wire on the top row. See Figure C.

7. Using an insulated jumper wire, short Pin 15 to the

power board ground lug for 10 - 15 seconds. A click

sound will indicate when the controls are reset.

See Figure C.

10. Turn OFF the refrigerator.

11. Disconnect the 12 Vdc power positive and negative

wires from the power board.

12. Install the power board cover.

13. Reconnect the following to the power board:

a. Spark/sense electrode assembly wire.

b. Solenoid gas valve wires.

c. AC power cord.

d. 12 Vdc positive and negative wires from the

power board.

14. Place refrigerator in service.

8. Turn OFF the refrigerator.

9. Turn ON refrigerator. If "n" or "no co" code

displays, repeat steps 7 - 9.

NOTE

A jumper wire to short Pin 15 to ground can be made

from a six inch long insulated 22 AWG wire with a 1/2

inch of insulation stripped from each end.

Keep me posted and thanks for the question,

Ronnie
