fridge goes to "check" light
Posted: August 27th, 2014, 12:31 pm
My fridge is a Dometic RM2663. At first, it couldn't do anything... dead. Then I opened the main LP gas valve (haha). The real funny part of that is the first "valve" I turned was the cap for the fill connection haha. (made me laugh too). So the goldish handle just to the right of that.. main lp valve.. lefty losey.
Poof, she lights the pilot light and the wonderful "gas" indicator came on. For a while.. about 6-7 min. After lost of research and fiddling (note: everyone says to clean the little burner thing.. apparently that's a common issue.. even just a little rust dust in it causes problems.
Still no luck for me though. The quest went on. There's 2 connections high up the flume that I thought were sensors for over or under heating.. not so. The imprint and later research showed them to be the 12V and 110 heating elements. So, back to this "thermocoupler" thing I kept reading about. Not an expensive thing to replace, but I didn't have one on hand nor could I find a local store that might carry such a thing. The thermocouple is just above the sparker for the burner (think grill ignitor.. same idea).
I traced the wires back to the circuit board. Supposedly you can stick a volt meter on those wire with the burner on (in those 6-7 working min. you have) and see 25-35 milivolts. I couldn't get my meter to show me that.. I can't get my meter to show much much other than 12ish volts for DC. My fault I'm sure.
However, I got lucky anyway. Disconnecting and reconnecting the thermocoupler and wala.. I have fire.. for about an hour now. It's uhmazing (sarcasm, but hey.. it's the little things).
I'm going to replace the thermocouple with a new one some day soon.. as well as probably replace the circuit board with a "dinosaur" one (google their circuit board.. they're all the rave).
I should add some pictures..
