Frequently Asked Questions
Q: How do I know if my relay control board is failing?
A: Common signs include the AC not responding to thermostat commands, the unit running continuously without cycling, or the compressor not engaging when you set the temperature. If your thermostat display works but the AC doesn't respond, the relay board is often the problem.
Q: Will this board work with my Dometic wall thermostat?
A: Yes. This relay board is designed to receive signals from Dometic LCD thermostats and control the AC components accordingly. It's the interface between your thermostat and the cooling system.
Q: Is this a direct replacement, or do I need an electrician?
A: This is a direct OEM replacement. If you're comfortable with basic RV maintenance and can access your AC unit, installation typically involves disconnecting the old board and reconnecting wire harnesses to the new one. However, we recommend consulting your RV manual or contacting our expert support team if you're unsure.
