I have a Doemetic RM2862 3 way refrigerator. It is the original in a 2005 5th wheel. The freezer works fine on both AC and gas. The refrigerator does not work on either. I checked the main fuse (15 amp) inside the 5th wheel, the two under the plastic cover outside, plus the inline fuse that is outside. All are OK. The light on the inside of the refrigerator is on. When I switch the refrigerator off or on while on gas, I can hear it turn off or light up. The thermometer inside is attached to the first fin. The coil / condenser is hot to the touch, but not so much that it will burn you. What can I check to see if it is the board or something else? Thanks for your help.....
