Refrigerator trouble

Why would my refrigerator quit working on electric and when I switch over to gas it starts working again. Switch back to electric and will continue to work for seems to be a week nor more. Replaced the thermal switch but still having problems.

You might find a direction to try in here:

It is certainly an odd problem. Which switch did you replace, again?

It was the thermal switch or thermal relay switch. Supposed to shut the refrigerator down it it over heats. That is what it was doing originally completely shut down. Now it keeps running but quits cooling.

AH! You are referring to the stack over-temperature lockout.

You are correct. This recent addition to these units was a safety mod to shut the gas valve off if there was a fire in the flue.

Perhaps the safety switch did its job and shut it down due to a fire that might have damaged your AC electric element. As with most elements, the AC element expands and contracts with heat and perhaps there is a "swinger" short in the element.

Ohming the element when it is "running but not cooling" on AC may shine some light on your problem. You can also meter the heater board for voltage at the heater connection when it is "running but not heating" on AC for 120 volts (heater wires disconnected).

Yes that is the switch. Thanks I'll check those things out. What I don't understand I it will cool for a week or more and then stop cooling. Switch to gas to cool back down and switch back to electric and will continue to work. If the switch did it's job wouldn't it shut down the gas as well? Or shut down the whole unit from not running? That's what happened before I replaced the switch. The whole unit shut and wouldn't even run. Now you can hear it run but not cooling.

I had a problem like this with my fridge, but it flat out would not cool on power, worked great on gas.

Took it to the dealer Friday, they wanted to keep it there for 24 hours which could not did not happen.
It worked on gas just fine for the past two days, tried it on power here in SD. and for now is working darn good.

Dealer tech said everything was working as it should.

I am thinking there may be a problem but not a clue as to what.

I pressed the reset button on the switch the first time it happened and worked the rest of the trip. When I find the problem I'll let you know.
