Frig has been working fine. When I got up this morning it wasn't working, tried turning it on and nothing. I took a magnet and ran it across the little box outside and still nothing. The little box, can't remember what it's called but I believe it's a safety device, has a red light and it was on steady. Looking on trouble shooting suggestions, It's a Norcold 1200LRIM. Thanks

That RED light on SOLID (Recall Box) indicates the Stack High-High Temp Sensor has tripped (700*F)
When tripped ALL DC to fridge shuts off

So either the cooling unit has a 'Leak' (check for any yellowish residue in/near burner area or ANY place on tubing.
THAT means DEAD

No signs of leaking......
Has it Rained?
Have you washed the RV recently?
Water can 'short' the Recall Box little circuit board/sensor wiring etc

Hair Dryer to rid the box/wiring of moisture then Tilt Box more downward so it is less susceptible to moisture


Could just be a faulty Recall Box circuit board....most current version is 'E'
* look thru small opening on front of Recall Box and check which version you have ---if not 'E' contact Norcold for upgrade

IF not an 'E' the lower versions may/may not reset using the magnet

Strong Magnet held on face of Recall Box near top and then slowly move back/forth until you hear a CLICK and RED Light goes OUT

Is it time for your medication or mine?

Will the red light go out immediately when you reset with the magnet?

YES!

It is a 'Reed Switch' and can take several seconds to reset

IF magnet does NOT reset it....Light go out...then you can remove the cover and manually reset the reed switch

I have a Norcold 1200RIM. Every time I drove thru a rainstorm, that red light would come on and the switch would activate and shut down the fridge. I would have to get the hair dryer and dry off the switch and then take a magnet and reset it.

Then came the day it would not reset. I was on my way home from a 2 month summer trip, the weather was hot, so I decided to just by pass the switch so I could get the fridge working again. I of course, can not recommend you do this, but it is a simple process and it can get you working again.

When I got home I ordered the 110 volt HVAC cooling unit from JC refrigeration. No more fridge problems and the Norcold works like a residential unit.

Well I had my motorhome washed at a truck wash yesterday. They used a lot of water, so I'm thinking that's the problem. I haven't had any success resetting the switch with a magnet. How do you do it manually?

Won't reset if wet (or if not an 'E' version)

Remove the cover...use hair dryer and dry the circuit board

At very top center of circuit board is the reed switch

After getting it dried .....tilt it downward to limit exposure to moisture

Finally got the switch to reset. Found out one needs to leave the magnet over the area for 5 or so seconds before moving it. Just sliding the magnet back and forth wouldn't do it. Thanks for all the info. Much appreciated.

1. If you have repeated moisture related trips, that means the black box is probably compromised by rust.
2. Reset is easier and quicker if you disconnect the 12 volt power wire to the reset box. Doug
