Fridge runs warm when temperature climbs into high 80s

When a refer is in a slide room it has 2 outside doors upper and lower. Due to the fact that it is in a slide room the Dometic installed fan WILL NOT properly exhaust the hot air over the top condensor out that upper door. The correct fix is to install an additional fan just inside the upper door to help blow out the lower fans air. You will be amazed at the increased cooling performance. Depending on the OEM, they sometimes authorize the part and labor. Dometic will not authorize as the refer will function correctly as designed and is not responsible for install errors by the OEM's.

When the outside air temps increase YOU have to turn up the temp setting to '4' or '5'

No compressor side......but that absorption fridge in a slide the airflow is CRTICAL to removing the heat

And NO dead air spaces...top of fridge should be closed off...no open space/cavity and the air should be directed out the upper vent
As stated above...proper installation of fridge is necessary for good draft across the backside of fridge ...in thru bottom vent and out thru top vent
Clearances are important...should be no more then 1" between slide out wall and backside of fridge
Any larger clearance and 'baffles' should have been installed to properly direct the air flow

Fan is critical to helping more air when in a slide
FANS...more then one is even better



DOMETIC is NOT publishing/providing much in the way of Manuals for their new 'DM' line......use to be lots of info available!!

This is a standard Dometic RV absorption fridge mounted in a slide out which if not properly vented will deliver less than ideal cooling, particularly as outdoor temps rise. We do have internal fans in our motorhome's Norcold and in our TT's Dometic that I hardwired in, both do a great job moving air in the fridge and preventing frost build-up. Our absorption fridges have worked well for us but on a couple of rigs I had to improve flow behind fridge, how RV manufacturer installs them, especially when in a slide out, is critical to fridge reaching maximum performance. Might need to go back to dealer to determine if unit is properly installed.
