Furnace Repair

Weak Airflow or No Heat

If your camper heater blows cold air or doesn’t heat, it could be due to clogged filters, obstructed ducts, a failing blower motor, or low battery voltage. These airflow restrictions cause the system to overheat or shut off unexpectedly, disrupting comfort during your travels.

Our technicians inspect vents, ducts, motor connections, and propane supply lines, performing precise cleaning and repairs to restore proper airflow and ensure steady, efficient heating. Our every repair follows the Suburban, Atwood, or Dometic RV furnace troubleshooting guide, ensuring it works like new again.

We offer affordable, transparent pricing with insurance assistance and no hidden costs. As reliable camper furnace repair professionals near you, we service all brands and restore your heating system to full operation fast. Schedule your visit today.

Thermostat and Control Problems

If your heating system cycles on and off too frequently or fails to start at all, the problem may be with your thermostat or wiring. Simple fixes like battery replacement or thermostat recalibration can be done easily using an RV furnace thermostat troubleshooting chart, but wiring faults and sensor failures require professional attention.

We provide accurate thermostat calibration, repair, and replacement that keep the heater working efficiently. In the end, our team runs a performance test to ensure your thermostat responds accurately to the temperature settings. We fix both the malfunctioning components and the entire heating system replacement, ensuring a smooth and consistent heating on every trip.

Ignition and Electrical Failure

If your blower turns on but the heater doesn’t ignite, it’s often due to a problem in the ignition system, sail switch, or control board. We perform initial checks before moving to a full advanced electrical diagnosis to find which part is causing ignition failure.

Usually, a dirty or faulty sail switch causes ignition failure when airflow or temperature levels are out of balance. We clean, adjust, or replace these parts as needed, but if the circuit board or igniter is malfunctioning, we replace it with factory-approved parts to restore consistent ignition.

If your furnace has entered safety lockout mode after repeated failed ignition attempts, our professionals safely reset the system after diagnosing and fixing the root cause. We also clean and test the flame sensor, electrodes, and sail switch using manufacturer-specific methods.

Local travellers from Vancouver to Portland trust us for professional RV furnace repairs and replacement services. From basic checks to complex electrical or ignition problems, we fix the issue quickly at affordable prices, ensuring the heater lights fully, runs safely, and keeps your camp van heated in cold weather.

Intermittent Cycling or Overheating

If your furnace starts and stops unpredictably, it could be due to overheating, a faulty high-limit switch, or low gas pressure. These issues only appear after long-term use or moisture exposure that damages the control board. In some cases, it results from faulty wiring or connections, which interrupt consistent heating and cause short cycling.

We perform full diagnostic tests to locate short circuits, clean vents, check temperature sensors, recalibrate or replace worn-out limit switches, and test propane pressure. For units that are exposed to moisture, we inspect and dry out the control board to prevent short-cycling or shutting down too soon in the future.

Many travellers have restored smooth and steady heating through our expert repairs and now enjoy consistent warmth without sudden temperature drops. Book our RV HVAC repair service near you to ensure your furnace runs safely and efficiently through every season.

Gas Pressure and Regulator Repairs

If your heater keeps shutting down or burns with a weak flame, it’s often due to low gas pressure or a worn-out propane regulator. Low pressure prevents consistent ignition and causes the burner to go out shortly after lighting.

Our experienced repairman performs detailed testing as outlined in the Suburban RV furnace repair manual. We inspect the propane line, regulator, and gas valve for leaks, corrosion, or blockages, ensuring it is getting constant gas pressure.

During every gas pressure or propane system inspection, we also check the heating system’s combustion chamber for cracks or corrosion. This is one of the most critical safety repairs, as a cracked heat exchanger can leak carbon monoxide into your RV. Our technicians replace outdated or damaged parts with manufacturer-approved components, ensuring safety, reliability, and consistent warmth wherever you travel.
