Dino Board is NOT your issue

Runs fine on Generator but problem on Shore Power

Shore Power Supply is your issue.......not the heater element/Dino Circuit Board

They are higher quality, but CAN Have a Failure. NOBODY makes a 100% perfect product. Doug

"YOUR problem is simple, you used a NON Norcold control board."
:h :R

That may very well be true Doug, perhaps you can point me to where to buy a Norcold control board?

Took motorhome to my sons’s house to verify problem wasn’t with my home/shore power. Brand new grounded electrical service, still shows same error.

So you have replaced both the heating element and the controller board?

Yes, and I just tried running the fridge on the genny, unhooked from shore power and it seemed to run without errors. I ran it for about ten minutes without error, when on shore power it was failing within 2-3 minutes.

You need to check the Shore Power voltage and frequency. Doug

PS, This is something I have NEVER seen or heard about in 41 years as a RV tech. I have worked on thousands of RV refers. YOUR problem is simple, you used a NON Norcold control board. You also need to contac Dino for help. If at our shop and it DID show the error on our shop power, then it would be obvious the Dino board is the problem. To verify I would install the correct Norcold OEM part.

Both AC Heaters were Norcold parts, correct part number, wattage, etc. Both control boards were from Dinosaur Electronics. Both AC Heaters were checked and were within specs while still failing.

Norcold 982 uses a 300W element and should measure 38 - 42 Ohms
