Common RV Furnace Problems and How to Fix Them.

Your RV furnace is essential for staying warm during those chilly nights on the road. But like any appliance, it can run into issues that leave you shivering. Understanding common RV furnace problems and how to fix them can save you time, money, and discomfort. Here’s a step-by-step guide to diagnosing and resolving the most frequent furnace issues.

Common RV Furnace Problems

1. Furnace Won’t Turn On:

   • Possible Causes: Faulty thermostat, dead battery, blown fuse, or lack of propane.

   • Solution: Check the thermostat settings and battery power. Ensure propane tanks are full, and inspect fuses or circuit breakers for damage.

2. Blower Turns On, but No Heat:

   • Possible Causes: Ignition failure, dirty burner assembly, or malfunctioning gas valve. Most common is a bad sail switch.

   • Solution: Inspect the igniter for dirt or wear. Clean the burner assembly and ensure the gas valve is operating correctly. Remove furnace access panel or furnace from its mounting point. Test Sail Switch.

3. Furnace Cycles On and Off Too Quickly:

   • Possible Causes: Overheating due to restricted airflow or a faulty thermostat. Thermostat could be mounted in the wrong area of the RV.

   • Solution: Check air intake and exhaust vents for blockages. Replace the thermostat if necessary.

4. Strange Noises:

   • Possible Causes: Loose components, worn blower motor, or debris in the fan.

   • Solution: Tighten screws, inspect the blower motor for damage, and clean out any debris.

5. Weak Airflow:

   • Possible Causes: Dirty air filters, clogged or poorly installed ducts, or a failing blower motor. Low battery could be a cause.

   • Solution: Clean or replace air filters. Check ducts for obstructions and inspect the blower motor.

Troubleshooting Steps

1. Check the Thermostat:

   • Ensure the thermostat is set to the correct mode and temperature. Replace batteries if it’s not functioning properly.

2. Inspect the Power Supply:

   • RV furnaces typically rely on 12V power. Test the battery voltage and ensure your RV’s power system is working correctly.

3. Verify Propane Flow:

   • Check that propane tanks are full and the valves are open. Inspect the propane regulator for leaks or malfunctions.

4. Inspect Coleman AC Wiring:

   • If you have a Coleman AC unit, note that the power wire for the furnace comes from the AC control box. Coleman AC units are wired directly through the control box to the furnace, which can complicate troubleshooting. Ensure all connections in the AC control box are secure and functioning properly.

5. Clean the Furnace:

   • Turn off the furnace and clean the burner assembly, fan, and vents. Use compressed air to remove dust and debris.

6. Test the Ignition System:

   • If the furnace won’t ignite, inspect the igniter for dirt or wear. Replace if it’s faulty.
