Frequently Asked Questions
Q: How do I know if my thermostat control module needs replacement?
A: Signs include the display not turning on, the system not responding to temperature adjustments, furnace or AC not cycling on/off properly, or error codes appearing on the screen. If your HVAC system runs constantly or won't start at all, the control module is often the culprit.
Q: Will this module work with my specific RV model?
A: This is an OEM Dometic OT Series module. It's compatible with any RV using the OT Series thermostat system. Check your current thermostat or furnace documentation to confirm you have an OT Series setup. Our team can help verify compatibility if you're unsure.
Q: Is installation difficult, or do I need a technician?
A: The OT Series module is designed for straightforward replacement. Most RV owners can swap it out by turning off power, disconnecting the old module from its wall mount, and plugging in the new one. However, if you're uncomfortable working with electrical components, we recommend consulting a qualified RV technician.
