What could cause my RV fridge to stop working while the freezer is still operational?
The issue of an RV fridge working while the freezer continues to function is often rooted in airflow problems. RV refrigeration systems depend heavily on proper air circulation, and if the airflow is blocked (for instance, by a buildup of frost or iced-over vents), the fridge may not receive the necessary cooling. Additionally, the refrigerator’s cooling unit may have faulty components like the thermostat or a malfunctioning evaporator fan, which can impact the fridge’s ability to maintain cold temperatures.
Another common source of problems could be the absorption system itself. In an absorption fridge, ammonia is heated and circulates through the cooling unit. If the ammonia is not circulating efficiently due to a blockage or low ammonia levels, the fridge will not cool effectively, while the freezer may still maintain colder temperatures. Regular maintenance and checks can help identify these issues before they escalate.
How do I troubleshoot my RV fridge when the freezer is cold but the fridge is warm?
Start troubleshooting by checking the temperature settings and ensuring that the fridge’s controls are set appropriately.
