Common RV Service FAQ
Before you call for service, check these common "quick-fix" solutions for your RV systems.
My furnace blower runs, but there is no heat.
If the blower is blowing cold air, your furnace isn't "igniting."
-
The Fix: Check your propane levels and ensure your tank valves are fully open. If you have gas and it still won't ignite, it may be a faulty sail switch or igniter.
-
If the blower doesn't come on at all: Check your 12V fuse panel for a blown furnace fuse. If the fuse is good and it still won't run, Contact us to schedule a diagnostic.
I have no hot water, but the heater is "on."
If you can hear the heater working but the water is cold at the faucet, your bypass valves might be the culprit.
-
The Fix: Check your water heater's bypass valves (usually located behind the unit). If they are still in the "Winterized" position, the hot water is being blocked from entering your plumbing lines.
Why won't my RV refrigerator get cold?
RV fridges rely on a tight seal and consistent airflow to stay cool.
-
The Fix: Inspect your door seals (gaskets) for dirt, food debris, or tears. Ensure the door is closing fully and latching. Even a tiny gap allows heavy cold air to "pour" out, preventing the unit from reaching temperature.
My Air Conditioner isn't keeping up with the heat.
It is important to remember that RV A/C units are not as powerful as residential home systems.
-
The Fix: Start early. In the Tennessee heat, set your thermostat to your desired temperature early in the morning. If you wait until the RV is already 90°F inside, the unit will struggle to "catch up." Keeping your blinds closed and using an awning can also help the unit maintain comfort.
