Fixed Our Refrigerator thanks to RV.Net

Our Norcold 1210IM refrigerator quit yesterday and the fault code indicated it was thermal sensor switch issue. This model was part of a recall and apparently the previous owner had the recall part replaced while in Texas back in 2011. Norcold said I had to take it to a authorized RV dealer to have it checked, and only they could order a new sensor which I believe would cost nearly $200. My wife found how to reset the switch by simply using a magnet somewhere here on RV.net, so I used my magnet from my workamping name tag and followed the instruction of simply moving the magnet over the read light on the sensor. I did that, heard the click of the switch, and now 24 hours later it is still working. Hope this helps someone else, and thank you RV.net posters, you saved the day again.

    Im sorry to jump on your thread:

    I've been having issues with my 1210IM model. It throws a "no co" code on the display. The black box on the rear heating coils has stopped working.

    I checked everything:
    DC good, AC good, no leaks, no obstructions, and gas ignites. In the diagnostics display I show a 54 degree temp. After letting the fridge run for about an hour the temp showed 57 degrees; it shuts down showing the code "no co". I tried resetting the control board by shorting out pin 15 to ground. I've used the diagnostics display by pushing both "temp setting" & "mode" buttons. Then I cycle through all screens "1 thru 0" according to the service manual no faults are showing.

    Before storing: the fridge operated, after storage the fridge doesn't. I bypassed the black box by connecting the DC in directly to the board and the fridge tries to operate in both AC and Gas modes.

    I plan to replace the thermistor after reading something on the web. Also, I saw in the service manual about two fans that are behind the fridge to help venting. I don't think I ever heard them turn on. Should you be able to hear the fans; especially in temps of 120 degrees? It is winter now: Feb 2015 and the temps are 40 to 70 degrees.

    I read in your thread that you used a magnet to reset a box; is this the box that is attached to the coils? I know it is some type of relay or switch; I might just tap it to see if the contacts will release. I was going to remove it and disassemble to see what it is.

    I'm about to remove the fridge altogether and tear it apart from limb to limb. Everyday I think on what could cause the issue and I try something new each day with little to no results. This weekend I am going to dive in elbows deep if I can't find a simple resolution.

    If you having any suggestions let me know.
    Thank you.

    (Edit): before I stored the RV it was plugged in. We had a brown out and the fridge acted up with low AC/DC. After I reset everything it started working again. Then I stored it and now issues. I think the black box took a large surge and fried.

    YES the recall box can be reset using a magnet BUT the real question is WHY did it trip?

    The recall is to protect from high heat source (Fire Potential).
    The sensor installed in upper section of flue is set to trip at 700*F. When it trips ALL power source is shut-off.
    Now some of the recall boxes have had failures causing unnecessary trips.
    The faulty recall box will be replaced with newer version without cost.

    You should have it inspected/tested......did it trip on high-high temp or due to faulty box??
