Here at Arizona RV Service, we know that a working furnace is what keeps the camping season going when the desert nights get cold. There’s nothing that ruins a trip faster than waking up freezing because the heater decided to quit. To help you avoid that, we want to share some practical heater system check & repair tips—the same advice we give customers who stop by our shop.
Check the Simple Things First
Honestly, most of the time, a “broken” furnace is an easy fix. Before you start worrying about a big repair, run through this quick checklist. First, are you sure you have propane? It sounds silly, but it happens to everyone. Next, check your thermostat. If it uses batteries, pop in a fresh set. Finally, make sure your house batteries are charged up, because the furnace fan and ignitor need that 12-volt power to kick on. These basic steps solve the problem more often than not.
Look and Listen for Clues
Your furnace needs to breathe to work safely and efficiently. Take a walk around your RV and look inside the exterior vents. Wasps and other critters love to build nests in there, and that can completely block the airflow. Inside, just make sure bags or floor mats don’t cover your floor vents. Once you know the air can move, turn the furnace on and just listen. A healthy furnace will start with the whir of the fan, followed by a faint ticking of the ignitor. If you hear loud squealing, grinding, or banging sounds, that’s a clear sign to shut it off and investigate further.
This Safety Check is a Must-Do
Of all the heater system check & repair tips we offer, this one is the most important. Please, take a moment to test your safety detectors. Push the test button on both your carbon monoxide (CO) detector and your propane leak detector to make sure the alarms are loud and clear. These devices also have an expiration date printed on the back. They need to be replaced every few years to be effective. Think of them like the smoke alarms in your home. You have to know they’ll work if you ever need them.
Knowing When to Call for a Hand
If you’ve gone through these steps and the furnace still won’t light, blows cold air, or keeps shutting off, it’s time to call a professional. That’s when the problem is likely a deeper issue, such as a faulty sail switch, a bad circuit board, or an issue with the gas valve. Trying to fix these parts yourself without the proper training and tools can be dangerous and potentially cause more damage.
