You are not the first , nor the last to do this I suspect. You might try removing the board and drying with a hair dryer. Then let it air dry under a fan for a few days. It has worked for me in the past. Good luck..

And putting a wet cell phone in a baggie of white rice has worked for me.

I just tried bypassing the black box and the fridge cut in so obviously it is the box that is the issue.

76 degrees out and I had to turn the furnace on to dry it out. We'll see what happens.

I've used a hair dryer when mine got wet from blowing rain; just watch the heat, (doesn;t get to hot) worked for me.

I know this is going to sound strange -and I have not tried it myself - but I have read several different threads on another forum where you can take a magnet and run it on the limit switch by the led light. If you hear a click, then the switch should work.

I have no idea if it works and of course I never saw these threads until AFTER I had my Norcold repaired.

Try it, what could it hurt?

Here is one of those threads which took place yesterday. Apparently the magnet trick worked for the OP.

Does anybody know where I can purchase the Norcold 634677 Temp Sensor without having to take the RV in and pay for a service call?

Here is another company that sells a controller

Purchase | Dometic Control | Norcold Control | RV Fridge Safe

This has positive reviews although I have not installed.

Takes a rather strong magnet, but the black box can be reset.

I agree, try the KISS principle first. Get a magnet, hold it to/swipe the edge of the black box until the red light goes out/resets. Then if that doesn't work you can spend money on a new black box.
OTOH, if something other than the recall black box is the cause, try this Norcold reset pdf from bryant RV.
Here is another pdf for resetting the power board.

Dogpatch sounds like he isn't having a good day1
Someone suggested he use a hair dryer to dry out his control box. I wouldn't have taken the risk and suggested this to the poor fellow.
These dryers get hot. Heat causes fires and with Dogpatch's luck his luck might turn even worse.

Actually, I've been through this very same deal a couple of months ago. However, mine was caused by a pinhole leak in the water line to my ice maker that sprayed the Norcold recall module.

First, IF you are SURE that no overheat condition existed AND you NEED to have the refrigerator operating, you can simply jump the recall module by removing the 12v in and the 12v out wires from the module and inserting a jumper wire between those two wires. That process completely bypasses the overheat protection provided by the recall module.

It is POSSIBLE that the water on the module has caused it to trip, even though no overheat condition existed. The module, after it's dried out, MAY still be working. In that case, using a strong magnet placed on the module near the red light MAY reset the module.

It is POSSIBLE that the water has damaged the module in a way that it needs to be replaced. If that's the case, you'll probably need to have an authorized repair facility do that replacement. They'll be asked by Norcold to certify that the reset procedure (magnet) did NOT work. Norcold will send a replacement module to the repair facility. The good news...this is all covered by the recall.

At least, that's how it worked for me.

I did see a module advertised for sale on ebay.

Good luck.

Take care,

I have used the strong magnet trick a couple of times after washing. Blue beacon or my self.. Pass magnet somewhat slowly over black box with refer off.
Magnet size about 3/4 x 1 1/2 can be sourced at lowes or any good hardware store. Stronger is better. I keep mine in the refer access compartment ready for next use.. Good luck

She can always tell when something has happened by the sounds coming from the garage. I have invented many choice words not recognized in the English language a few times over the things that happen. She knows to stay away at a time like that and give me time to let her know what I did.

I love that about her!!!

Just because I'm out in the garage swearing doesn't mean I'm not having a good time.
