Dometic 75 - RM77 : Problem with how to...

Hi.
I think I have to face a problem with my fridge.
Today it doesn't seem to work on electric.
It was fine till this afternoon. It was pretty warm outside, around 86F and when it was time to open it for a good beer it was not too cold inside...
I put it on gas, so I am waiting to see if it's ok now.
But so far from what I checked when it was on 110v the heater seemed to stay cold. So to me it doesn't work. But is it the heater or is it the thermostat that doesn't call for cold.
How can I figure that out?
How hard is it to find a thermostat on such an old unit or a heater...
thank you for your help

Dufferin,

It's easy to see if your AC element is operating. You have to isolate it from the fridge's system.

1. locate the element in the boiler section of the fridge. It is a 1/2" or so L-shaped rod with the long section buried in the boiler and the short section visible.

2. locate the 2 wires coming from the element and follow them to the control box.

3. remove the wires from the control box.

4. make a pigtail (usually with 2- 1/4" male spade connectors) with an old extension cord (2-wire is fine). Attach the connectors to the cord. Polarity does not matter here.

5. plug in your extension pigtail to a known working 120VAC outlet. Let the fridge run overnight.

If your element is OK, the box will be VERY cold when you open it.

You can also do a continuity check of the element, but Dometic prefers to do the above procedure as a fool-proof verification.

Good luck and be sure to report back with your results.

Open up the insulation wrap around the old tube that holds your AC heating element. If you're lucky.....there just might be another tube sitting right next to that one.....EMPTY!

Some cooling units were made to accept 3-way operation, but many were only used in LP/120VAC operation. This extra heating element tube is for the 12VDC heating element, which you should not have present in a 2-way unit.
