Another Refrigerator Failure...

[FlyboyTR]

Norcold N300-3:

For those of you that have followed our refrigerator debacle in the Mouse Motel, know that I had to replace all the controls, gas valves and the Thermocouple. The thermocouple is the tube that sits directly above the flame when operating the Norcold N300 on LP. The flame/heat creates a tiny voltage and that voltage is what makes the indicator needle move into the green and also that same voltage keeps the safety gas valve open (the red button you have to hold in to light it...it allows the gas to flow).

Anyway, the thermocouple I ordered 5 months ago was off of Amazon and was, like most things, a Chinese knock-off. Well, it failed and we were not able to cool the fridge on LP. Amazon is allowing me to return it for credit. I have ordered a genuine Norcold factory thermocouple from RV-Upgrades. It arrived today.

We installed it and tested the voltage. After one minute it is creating 29.2 millivolts; perfect! The failed thermocouple was only producing 14.3 millivolts; not enough to hold the safety valve open and allow things to work!

Shipping from RV-Upgrades was super fast. I'm very pleased.

You've had enough experience to know, I'm sure, but I'll repeat if for possible benefit of others.

I don't believe that the thermocouple sits ABOVE the flame. It must sit IN the flame. The words often used in the instructions are BATHED in the flame.
