FAQ
What is the difference between ducted and non-ducted RV air conditioning systems?
A ducted RV air conditioning system uses a network of ducts to circulate cool air throughout the vehicle. This system is more expensive and complex to install but provides better cooling performance and energy efficiency. On the other hand, a non-ducted RV air conditioning system does not use ducts and instead relies on the natural flow of air to cool the vehicle. This system is simpler and more affordable, but often provides inferior cooling performance.
How do I troubleshoot a Dometic RV thermostat that is not working?
If your Dometic RV thermostat is not working correctly, there could be several reasons why. Here are some common issues and troubleshooting tips:
- No power: Check that the thermostat is receiving power from the RV’s electrical system. Verify that the circuit breaker and fuses are not tripped or blown.
- Wiring issues: Inspect the wiring connections to ensure they are properly connected and not damaged. Refer to the wiring diagram to confirm the correct wiring connections.
- Temperature sensor issues: Check that the temperature sensor is properly positioned and not damaged. If necessary, replace the sensor.
- Battery issues: If your thermostat is powered by batteries, check that they are not low or depleted. Replace the batteries if necessary.
- Malfunctioning components: In rare cases, the thermostat may be defective or malfunctioning. Contact Dometic customer service for further assistance.
