With high summer temperatures, the refrigerator in my fifth-wheel was not cooling like I thought it should, so I bought a 12-volt DC fan at Walmart. At the refrigerator’s rear-access panel, I hardwired the fan into the RV’s 12-volt DC system and let it run 24/7 (thermostatically controlled fans for this purpose are also available), blowing hot air toward the top vent. The on/off switch remains in place, should I want to turn it off. Now the contents in the fridge are kept cooler.
