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.
Is it time for your medication or mine?
