RV Furnace Issues & Solutions

---

Why does my RV furnace keep turning off?

If your RV furnace keeps turning off, it’s often a sign of an underlying issue that needs attention. Common causes include dirty air filters, blocked vents, low propane levels, thermostat malfunctions, or problems with the furnace’s safety sensors. 

Ignoring these signs can leave you without heat on chilly nights and may lead to bigger, more costly repairs down the road. Regular furnace inspections and timely maintenance ensure your system runs efficiently, keeps your RV comfortable, and prevents unexpected breakdowns while traveling.

• Dirty or Clogged Air Filters: Restricted airflow can cause the furnace to overheat and shut down.
• Low Propane Supply: Insufficient fuel prevents the furnace from staying lit or heating properly.
• Faulty Thermostat: Malfunctions or misreadings can cause the furnace to cycle on and off incorrectly.
• Ignition or Pilot Light Issues: Problems with the igniter, flame sensor, or gas valve can stop the furnace from firing up.
• Blocked Vents or Ducts: Obstructions reduce airflow, forcing the system to shut down to prevent overheating.
