Norcold 1200 dead inside, flashing red light outside panel

Fridge won't turn on inside. Outside under panel there is a red light flashing on small black module. Has 4 wires. One says 12 V out.

The Norcold High Temperature Module has three different failure codes.

Solid Red Light - Lock out due to a high temperature sense issue.

Flashing Red Light - 1 flash per second - Low battery voltage sensed.

Flashing Red Light - 2 or 3 flashes Per second - High Limit Sensor (Brown Wires going to Flue) failure.

Might be time to find a trained professional.

Water and high humidity will trip that controller.

Thank You Old-Biscuit. Checked for yellow residue and found everything clean. Did wash the coach before putting it away last trip. Jumped the 12 v controller and everything works. My dealer is ordering a new recall controller. Leaving for Cranbrook, BC tomorrow.

Thanks again!

I have no experience or affiliation with this company but they offer a 100% 120VAC compressor conversion for your fridge that seems like it would be a great way to go if you need a cooling unit (or even if you don't) JC Refridgeration

That RED light flashing is indicator the 'recall box' has shutdown ALL 12V DC power to fridge

*Either because it did its job.....trip DC and stop all heating functions due to High-High Temp being sensed via the thermal disc on boiler stack.....temp in excess of 700*F
*Tripped because module got WET
*Tripped because the module failed


Real issue is WHICH one caused the trip????

Do you see any 'yellowish residue' around/on burner area....remove shield and inspect
Do you smell any ammonia?


Did you recently wash RV..spray a little water into fridge area via vent cover?

What Revision number is module?
(Look at REV # via open area---latest was 'E')


You can reset the recall box using a strong magnet
Place it against face of box at top and slowly move back/forth ----should hear click and RED Light go OUT
Especially IF you were NOT operating fridge and found it tripped.
Otherwise could be due to overheating caused by cooling unit blockage.
