A: This part replaces #33475 and fits Dometic water heaters that used this thermostat. Verify your current part number matches before ordering. Contact our expert support team if you're unsure.

Q: How difficult is installation?
A: Thermostat replacement is straightforward for most RV owners. You'll typically need to drain the water heater, remove the old thermostat, and install the new one. Your owner's manual provides step-by-step instructions.
