Dometic Refrigerator In Warm Weather

I have noticed my Dometic 2820 refridgerator gets warmer and warmer the longer it is on. I have been measuring this with a probe inside the box. When I contacted Dometic they said this ic common with Airstreams because of the space behind the refridgerator and suggested the instalation of a baffle across the back of the ref. to correct this.

My question. What has been your experience with the inside temperature of your refridgerator after a week or so of operation.

Try to keep the refrigerator side of the AS in the shade when possible it really helps keeping the box cold. If you put a baffle inside the door make sure there is plenty of ventilation. However, again, keeping that side of the trailer in the shade is the best fix.

Install a fan or fans

I have used a 12v surplus computer "muffin" fan with a resistor in series so that it runs on about 6 volts. Put it anywhere that will increase the airflow over the finned radiator on the back of the refrigerator. I have also used 2 small surplus fans wired in series. The fans run slow, but only a whisper of air is needed to improve cooling.

Camping world, et al, have plenty of fans for less than 420 with thermostats so that they run only when needed. Some are even solar powered.

On another thread, there was a part number for a thermostat that will turn the fans on onlywhen the compartment gets hot.

Some folks are installing expensive fans, but, IMHO, that is overkill. A regular fan will be silent when run on part voltage and will move plenty of air. After all, the refrigerator was designed to operate with just thermal air movement; any increase in air movement is a bonus.
