norcold N400 refrigerator

[strokershovel]

Hi everybody, I'm new here and I have searched everywhere I can think of to fix my problem. I have a 2002 Lance lite 825 truck camper with a Norcold N400 refrigerator that won't stay lit after you release the button. I have a new thermocouple for it but I also am aware that it could also be the thermocouple interrupter. The problem is that the interrupter is discontinued and I can find it nowhere. I can just bypass it but I like the safety feature of it. I'm sure I'm not the first person to run into this problem and the fridge works great on 120v power but there are times I need to run it on propane.
Thanks, Keith

That is usually part of the replacement safety valve. Also, that is what turns the indicator light on. It should NOT cause a problem with keeping the LP flame on. Hence, I have never had to replace that particular part. Doug

The interrupter is what the thermocouple screws into and shuts the gas off if the thermocouple does not send the signal that the flame is going

No, the safety valve does that. The Interrupter just sends the signal to the inside light display. There are RV refers that have NO inside indicator light and just have the safety valve that opens and shuts off the LP(Thermocoupler connected). The safety valve is the same for refers. This type model has the interrupter to send the signal to the light. It may SEND the Thermocoupler signal THRU itself to the safety valve, but it is the safety valve that opens and closes from the Thermocoupler millivolt signal. Doug

Yes, but for the price of a interrupter I wanted to change both while I had the refrigerator out

I suspect $24 is cheaper than a new frig...........

That refrigerator is no longer available, the closest one is $1400. It works just fine on 120v.

Being 20 years old I would start looking at a new frig, you could spend a lot of money fixing this one and it could die in 6 months.
