Norcold F code

[jerry1]

I have a Norcold N822 refridge. When you turn the button to LP: the gas will flow, the igniter will click/spark, lighting the burner. The igniter will not stop clicking/sparking even though the burner is runnig properly ... then I get an F code and the refrig shuts off in about 60 seconds.

Also has anyone every changed out a thermocouple in a unit like this?

The control board is not seeing that you have a flame present. First insure that you have a good, clean and tight connection for the igniter & all of control board and re-liter. The flame must slightly envelope the igniter for the dc millivolt production needed for the control board to know you have a fire present to then leave the gas valve energized. To test the thermocouple, you will need fire and a means to check millivolts at the connection end of it. If these check good then you have a bad control board.
