  1. Just an update. Got the new unit installed a few weeks ago and went on a few trips. Fridge is now cooling great. Even had ice start to form on cooling fins so can't ask for much more. Did have to straighten out the frame a bit from shipping but sounds like that is common. Other thing was I couldn't get my trailer's outside cover on. Needed to remove the gas burner mount and cut 1" off then weld it back together and good to go. Thanks for all the help. It's nice when you have to make a large money investment when troubleshooting to have someone else agree with your diagnostics.

    I have replaced two cooling units over the years. Not that bad of a job. What we did was put our coffee table covered with a piece of carpet at the bottom of the refer cabinet, slid the refer out of the hole standing it on the coffee table. Then we laid it door down on the table after removing what needed to be done in the cold box and freezer. As per instructions just followed thru. One thing I distinctly remember was the prying loose of the old coil. Thought that was the end of the reefer. But followed thru and everything went according "to Hoyle" even though "Hoyle" wasn't there. Slid back in the hole connected everything, vacuumed up the floor and within several hours it started cooling down. 

    Thanks. Was trying to think of something to slide it out on. I'll see if I have a table the right height.

    Sounds like the cooling unit ours did the same. The Amish cooing unit from Indiana is far superior to the OEM unit  our ESP plan covered the cost of replacement.

    Thanks. I was just looking at RV Cooling Unit Warehouse that claims to sell the Amish units. Is this the same place you're talking about and if not do you have contact info?

  4. Hi,

    Last trip out our fridge stopped cooling. I've checked other users queries and this is what I know. Dometic RM 2652 in 2006 trailer. I assume it's original. The thermistor read about 2k ohms in 90 degree weather but went up to near 9K ohm in ice water. In gas mode the flame lights and stays on. In electric mode the element pulls 2.78 amps which matches the 44 ohm element. It switches between modes properly. The chimney gets hot and the lower pipe into the cooling unit gets warm, I can keep my hand on it. Feels like near ambient temp on the upper pipes out of the cooling unit. I've never smelled ammonia inside and don't see any green residue outside with the unit still in place. The lights on the front panel all work as well as the interior lamp. I've downloaded the service manual as suggested. I've also removed all power from the board to do a hard reset. The two fuses on the control board are good. The vent seems to be clear.

     Now what? Is the purpose of the control board to turn on the heater as needed? If so I guess it's working. Could I have a leak up high on the coils that I can't see yet? Any way to test ammonia level?

    Thanks,

    Randy
