This unit just started flaking out in the past few days - the symptom is no fan, no compressor and no internal light. I tested the outlet - it has power. I jiggled the cord - no effect. When I started looking around for a new unit, it spontaneously comes back to life - compressor is cycling normally, fan works, and light works. It will fine for 3-24 hours then croak again for 1-3 hours, then come back to life.

I don't think it's the starter relay because when it's in failure state, the light doesn't come on either. I never hear any relay clicking, so for all I know, it may already come factory equipped with a solid-state relay. (Mfg date 2000).

I notice that the wires from the relay box on the side of the compressor and the AC power cord all lead to a nylon Molex connector, which is plugged into a sheet metal panel, obviously hiding more control parts (I guess the temperature controls inside)...

Any ideas?

Hi.

According the diagram this unit is not equipped with any electronic controls.Most likely the problem is within power supply harness or there more then one problem.
For example: bad lights (door switches) and bad defrost timer or cold control.
It's hard to believe in that, but things happen.
So the next time it'll happen - use the flat screw driver to slowly turn the defrost timer's shaft CW until it clics. If the fridge kicks on - replace the timer.

Here are the breakdown diagrams and Liner parts for Roper RT18VKXJW00 - AppliancePartsPros.com

Post the results.

Simon.

Howdy - thanks for the quick reply. I don't think it's the door switch because either all three work (light, fan, compressor) or none. So I will try your suggestion with the timer. Also I guess it could be in the harness, although I tried jiggling that around to provoke it...

Thanks again.

Hi.

First check the power supply.The cord, connections and you power outlet. Plug the fridge in to different receptacle.
