Looking for Dometic DMR702 service manual

I have been having a lot of trouble with my fridge. The pattern seems ambient temperature related. During the cool nights in the CO mountains off the grid, the unit would not run until about 10am. This past week it snowed about 10" and stayed near or below freezing for several days. It would not ignite these cold days. Now back in the warmth, I see the igniter wire is pretty crispy where it enters the ceramic piece of the igniter. Not sure the will solve the problem, but time to replace regardless.

Not sure this matters.. furnace worked fine, stove, hot water heater -- all good. End of the propane line is the fridge. There was also about 1/8" of frost below the propane level in the tank I was using at the time.

Two questions for the group:
1. Where can I find a service manual to ensure I get the right part(s) when needed?
2. Any thoughts on my sporadic fridge?

Thanks
Dave

    Interesting point on the Spark Electrode. You are saying it's two-in-one sparker AND thermocouple. Correct?

    Do you feel this could be related to my apparent ambient temperature issue?


    AS long as the refer stays lit and does NOT throw a red light or error code, the Ignitor will have NOTHING to do with cooling problems. Kind of like saying, I have a slightly burnt Spark Plug wire and my Dash AC does not cool correctly. NOT related. Doug

    Installation/Operation Manual
    Clearances for installation/Component ID/Wiring Diagram etc
    DMR702/DMC702 Manual

    Parts.........
    NO PARTS LIST Available
    Even Dometic doesn't list any Renaissance Series Parts (DMR702/DMC702)
    Renaissance Parts

    Looks like a Call to Dometic is in order.....
    Have Product Number and/or SKU Number available (on data sticker


    As for that Spark Electrode
    That wire MUST be intact
    It carries the High DC Voltage that ignites the gas BUT it also is part of the flame proving circuit (milliamp signal that circuit board senses ---- no signal/DC is shutoff to gas valve)

    Dometic 2932781012 (Part number for spark electrode used on NUMEROUS Dometic Fridge Models....17" Lead)

    Nice doc to have on hand. A few parts numbers, but none for the igniter. Thanks for passing along, though.
