Newest development in refer, still not completely working
Iíve had some posts on my refrigerator woes in my Sunline. Itís a Dometic 2612, 2 way. At first I had no refrigerator operations, now I have some life wit ha few different turn of events but Iím still not completely fixed. I replaced my circuit board with a Dinosaur 711. I have cleaned all of the contacts. On the 120V side I still get no action at all. If I have the 120V plugged into my house, have the refrigerator set on ďAutoĒ and turn it on, Iíll hear a click eventually and most times the ďcheckĒ light comes on and pops the GFI breaker at my receptacle in the garage. I have checked the heating element by contacting the wires with my multimeter and Iíve gotten a 44.1 ohm reading. Iím not sure what that means but all I know is the refrigerator is not working on 120V.
A question I have, does the 120V use any propane at all? Occasionally (last night) when I turned on the refrigerator using 120V it sounded like the burner trying to light or some similar sound. Or does 120V just rely on the electric heating element?
Onto the propane 12V a few things happening here. I actually pulled the 120V plug since itís not working to default the refrigerator to 12V. I started off by manually lighting the heater as my igniter did not seem to work. After a few hours running in ďAutoĒ mode the ďcheckĒ light would come on most likely due to the igniter not being able to refire? So then I put the refrigerator in ďmanualĒ mode (constant run) and manually light the burner. It runs for 10-15 hours and somewhere along the line it goes out with the ďcheckĒ light illuminated. Iím not sure why it will run for hours and then shut off? The gas is full, the battery is brand new and itís plugged into the garage receptacle. No last night I was double checking a few things, re-cleaning contacts, etcÖ All of a sudden the igniter is now firing and it lights the burner but after 30 seconds or so it goes out. This is the newest development so Iím not sure why after ignition it goes out? Is that a thermocouple issue?
I know there is a lot going on here but Iím determined to fix this thing. Itís been a learning experience and Iím getting to the point where I almost understand the entire working of the refrigerator but obviously there is a bit more to learn. Maybe you can help?
