Guest bobstromain Posted August 19, 2021 Share Posted August 19, 2021 I am in need of a new High Temperature Switch that is part of Norcold's Safety Re call. Mine has never tripped. It started intermittently dropping the 12 Volts just for a split second then right back on. This stops the 12 volts from getting to the board for a split second resulting in shutting the fridg down for a few seconds. Never has to be reset. This happens even when you first turn it on and all the pipes are cold so it is not due to overheating and it continues throughout the operation of the unit. I bypassed the switch and every thing runs perfect. In order to get a new one I must go to a shop they run a test and fill out forms then Norcold sells them the part. Earliest appointment available end of October . The numbers on this switch are 634677 Rev B Does any one who has converted to residential Happen to have this switch? I saw only one on internet that looks like mine but has different numbers and Rev Any comments are appreciated Bob St. Romain 04 Windsor Link to comment Share on other sites More sharing options...

Chuck B 2004 Windsor Posted August 20, 2021 Share Posted August 20, 2021 If my memory serves me correct, there were 5 revisions to that switch. Each revision lowered the temperature the switch would activate. That was done to keep the frig from catching fire. The fire would start at the 120 vac wiring for the heaters where those wires entered the flu tube. The higher temps would melt the insulation off the wires causing the bare wires to short out against the metal conduit going into the flu tube. The fix was to use a bake lite type housing that would not conduct the 120 vac current when it shorted out due to the high heat. The new housing along with the rev 5 was the final fix for the fire problem. I will try to get the pictures to Frank M to post on the group.

klcdenver Posted August 20, 2021 Share Posted August 20, 2021 You can have it for the freight charge. Then you can buy me a beer if we ever meet up. If pac n mail is open tomorrow I will get it coming your way. Do you want cheapest freight or something expedited? I never had to reset it. I have the whole norcold 1200 if you need other parts. It was working pretty good if not really hot. I just went ahead and switched it to a residential. Kenneth Link to comment Share on other sites More sharing options...

Ivylog Posted August 21, 2021 Share Posted August 21, 2021 I would recommend buying the ARP controller if you have a NoCold 1200. It’s better at controlling and preventing fires: https://www.arprv.com/index-amp.php 1 Link to comment Share on other sites More sharing options...
scottjo02 Posted August 22, 2021 Share Posted August 22, 2021 Kenneth (klcdenver) I would like to purchase the main electrical circuit board (the black box shown in my photo just above the fire extenguisher head). I am in Tulsa, OK. let me know what to do if you wish to sell it. Thanks Scott Jordan Link to comment Share on other sites More sharing options...
klcdenver Posted August 23, 2021 Share Posted August 23, 2021 This is the control board. Look at the part number on it to make sure it is the correct one for you. If it is make offer plus shipping. Kenneth Link to comment Share on other sites More sharing options...
