My RV Fridge is a Dometic RM2193. When the weather is cooler it works well. But when the outside temperature goes up, so does the temperature in the Fridge. On shore power at night the temperature in the Fridge got down to 28 degrees. So I know the system is working properly. Two days ago the outside air temperature was 99 degrees and the Fridge could not get any colder than 56 Degrees late afternoon. Much too warm for food storage. So I installed one ventilation fan to help draw hot air out of the rear of the compartment. In another test, the Fridge got down to 50 degrees when the outside air temp was 104 degrees. Still much too hot for food. So today I installed two more fans that are mounted directly below the coil fins and blowing air up into them. The weatherman says that it is going to get up to 107 degrees today. So I'm anxious to see what the additional fans will do. I'm not concerned about battery drain or noise inside the camper. I can barely hear them running when inside. And If I have the fans turned on I have Solar panels to keep the voltage up in the battery. I also have a generator is necessary. I just want safe to eat food!
