Another Norcold issue

Thanks to all and as Doug R.suggested, the heater element (X2) replacement fixed the GFI trip problem.

Then the magnet reset protocol fixed the red light that appeared while the refer was not plugged in at all.


All is well (for the moment)

Thanks again to all ...this forum is a wealth of great information !

If the thermocouple shows continuity, it's probably good. If it fails, it will show an open and the red light on the box will flash. If you get a solid red light, the problem is with the box itself. You may or may not be able to reset it with the magnet.
Norcold will replace the box for free, but will only send it to a certified tech. They will not give it to the owner.
You may want to do a little research on this. That's what I'm using now. Much better.

The red light on the recall can be caused by a slow drop in 12 volt supply in the RV. I normally do not recommend this, but since it has been posted on numerous forums----Right by the red LED run a powerful magnet over the box. This will usually reset the Box. It may take awhile but be patient. Norcold will replace a defective recall kit, BUT, the Rv'er must pay a check out fee for the service center to verify that the old kit is defective AND the cooling unit is not defective or the ventilation blocked. We charge 1/2 hour labor to check the refer and kit and IF defective then Norcold pays us an extra 1/2 hour labor to R&R. Doug

PS, regardless of what is posted on these forums, I have found very few recall kits defective(since the release of Rev E), there is either a bad cooling unit or a blocked ventilation or cooling fan problem. The recall kit kicks out when the flue gets to 700 degrees. The normal operating temp of the flue is around 350 degrees.

To update.....While waiting for the ordered 120 AC elements I checked all electrical boxes in the coach and all were good.
Elements arrived today and when I went to install same the red light in the "overtemp " box was on ... the refer was disconnected during this period so not sure how this occurred ?
Went ahead and installed the new elements and still had no 12 volt to the refer so no way for AC to come on and check if see if heating elements cured the previous problem.

As a temporary measure only..... I jumped the red and blue connections at the black overtemp box and was able to bypass the box and check to see if the heating elements cured the GFI trip problem...They did (thanks Doug)

I also checked the thermocouple on the chimney and it had continuity not sure if that confirms that it is functional ( maybe the fact that it had continuity confirms failure?)

So did the black box fail while sitting? Will Norcold replace the box ..is there a way to confirm failure ( other than 12 volt does not pass thru) and possible reason for failure

Long post but thanks for any ideas or next step checks ...I won't operate the refer without functional "overtemp" box

Thanks guys ..I will report findings after checking connections and replacing elements !

Thanks for all the guidance !

x3 Good point, element could be grounding to the flue. Agree with others, most likely the element.

Replace BOTH 120 elements. The cause is one of the Elements. Doug
