20 Most Recent Dometic RM2620 Refrigerator Questions & Answers

Hi Tom,

If your fridge quit working altogether, check your DC fuses in the fuse box, as well as the back of the fridge under the black plastic cover (3 amp). Though the fridge uses LP and 120vac to cool, it is controlled by 12 volts.

Since I don't know what does work I am kind of shooting in the dark. Does the ac heater get hot ? The spark ignitor is part of the control board. But won't work? I assume that you have a user manual but I am including a link to download one. https://www.dometic.com/f6e8a773-69f5-4624-9b35-54e8801da7af.fodoc Note that there are three fuses. B (12V control) and C (120V Heater) on the control board and a thermofuse L located on the stack. If L is good and everything else is good there should be 12VDC on J1 and at Fuse B

Your 'frige has either; a 12 volt power supply or, a gas flame to circulate the refrigerant gas to cause absorption refrigeration to work; check or, replace your power supply as it 1. holds open the gas valve relay, 2. heats the gas with a heating element.

i suggest u take ur rv ammonia refrigerator to ur rv dealer for a replace.. ammonia leaking can result in serious injuries, in tight places...

Get the manual from web site and be guided accordingly. Otr try google search for insstructions

Hello Paintinfool3, I have worked on these in the DISTANT past... They are a great CLASSIC design... Working on gas means you are 90 to 95% all good The electric comprises two basic elements only confused because you have both AC & DC modes. Just for simplicity sake the ELECTRIC section (heater & thermostat) section in the BELOW begins with SECTION 63... You need a volt-meter with an OHM scale... (the $9 kind... HARBORFRIEGHT gives away). There is a yes/no trouble shooting guide. Also CUSTOMER CONTACT numbers in the very back.
