Interesting Problem... My Norcold 1200 is flashing and beeping a failure... An AC HE which is indicating a problem with the electrical heating elements.
A measure of the resistance at room temperature of both elements finds that they are within tolerance.
All connections appear to be in order.
The refrigerator is maintaining temperature. Both elements are producing heat...
Other than the beeping and error code flashing I would not know there was a problem.
The only variable I know of is to replace the control board... I did pull and inspect the control board no sign of any problem...
Any thoughts?

I would try taking a pencil eraser to the contacts on the control board. To clean them

HE AC means that one of your heaters has failed by being OPEN. That can happen intermittantly and the Element/s can OHM out correctly. They can fail when running HOT. Thus the intermittant operation. When it happens again, you then clamp on a Amp meter to see which element is open. But, It would be better to just replace both elements at the same time rather than the one that is defective. Doug

Your getting a reading of 58-68 ohms on each heating element....correct?
Then the problem is at the power board. Check the yellow & brown wire(s) connections to power board.....otherwise may have to replace power board.

Thanks all for the responses... The Ohm readings are 64.3 and 66.1.. I have checked the resistance several times...after letting the elements cool and when they were still hot..
Doug, I plan on trying to round up two heating elements since I have everything accessible.
This morning I did take readings with a clamp on amp meter. I expected to see about .2 amps what I got was 1.63 and 1.51.
I also checked the temperature at the bottom of the stack.... 221F. The temperature inside the refrigerator is 34.1... The freezer section is at 14.1F...

The AMP draw is 1.7 on each element. Doug

Thanks Doug, neither element is drawing that much... One is lower than the other. I wonder what the threshold for the HE AC fault to be triggered?

120 elements either work or they don't. I would bet your line voltage is LOW or your amp meter is not accurate. The threshold is NO current as it senses an OPEN condition. No current flow at all. Doug
