Procedure to Reset NO CO Error
on Norcold Refrigerators

Occasionally the Norcold refrigerator can display an error message. The display will read "NO CO", which probably means "Not Cooling". It's not a serious problem but it is a bit tricky to reset. The following procedure describes what to do if you ever see the "NO CO" error code displayed on the front of your Norcold refrigerator's LED display.

One day this winter our ref. was beeping with a "no co" error showing on the panel. I turned of the ref. and turned it back on. In a few seconds the error was back. That was the worst thing I could have done.

I checked the book and the "no co" means that the unit is not cooling and you can only "reset" it once before you have to take it in for service.
After getting it serviced here is what I found out.
1. Once you reset it once the circuit board locks itself out.
2. There was nothing wrong with the ref.
3. There had been a power failure and the ref. had switched to propane. In a couple of days the propane ran out and the ref. shut down with that error. Not knowing what had caused the problem I reset the ref. with out correcting the problem first. Hence, it locked out and I had to get it to a Norcold dealer.

What the service man did was:
1. take off the cover of the circuit board
2. reset the board by shorting to ground, Pin #11 for 3 seconds.
Of course the problem had been corrected by now so the ref. is now working again.
