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 fridge 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 refrigerator.
3. There had been a power failure and the refrigerator had switched to propane. In a couple of
days the propane ran out and the refrigerator shut down with that error. Not knowing what had caused the
problem I reset the refrigerator 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 #15 for 3 seconds.
Of course the problem had been corrected by now so the refrigerator is now working again.
