Your RV’s water heater or furnace is essential for keeping you warm during those winter adventures. But like any other appliance, it can also face issues and leave you shivering.
The system may face a power issue, or there could be an empty propane tank to disrupt the gas supply. It is important to detect the culprit and then call an RV Repair Cedar Park TX service to make the required fixes.
Most RV water heaters operate on propane or 120V AC power. Any issue relevant to the power source may cause your heater to stop heating your water or completely fail to work.
If you are getting lukewarm water instead of hot, your water heater may not be the main problem. The issue might be in the bypass valve that you may have failed to reset properly.
You need to look at two different bypass valves. If you fail to close the valve at the back of the furnace, cold and hot water may mix, resulting in a reduced temperature.
The same happens when the internal shower bypasses remain open. Make sure that all valves are properly closed to prevent these things from happening.
Are you trying to turn on your water heater on gas but getting nothing? Can you hear the sound but don’t get any ignition? In that case, propane may be a culprit.
Check your tank and make sure that it is full. You should also open the valve properly and ensure that the propane is reaching the appliance.
Some RVs have Suburban water heaters. These ones have a hidden electric switch on their exterior faces. Your heater won’t work if that switch is off. This is a manual switch, so you will have to locate it properly and then flip it on to check the outcome.
Thermal cutoff is a small but impactful safety feature on most water heaters. If this blows up for some reason, the water heater fails to work.
To test its performance, you can check the thermal cutoff for continuity. If it fails the test, simply swap it out with a replacement part.
Replacing a thermal cutoff is fast, easy, and could be the difference between cold showers and comfort. However, if you want an expert to handle it, call an RV repair Cedar Park TX company like Overland to help you out.
If you have a furnace in your RV, you need to make sure that it is working properly to keep you warm on a winter night.
But sometimes the unexpected can happen. Here’s what may likely cause your RV furnace to stop working:
There could be multiple power issues with your furnace that you shouldn’t ignore.
For instance, the blower of your furnace requires 12V DC power to run. However, if your battery voltage is low, the fan may not spin fast enough and will fail to produce enough heat.
A bad thermostat could also be a reason. You need to ensure that your thermostat is set to ‘heat’ and the temperature is higher than the room temperature.
If your old digital thermostat isn’t working, replace its batteries if required.
If your furnace’s power source is propane, check the status of the tank. If it's empty, your furnace will not work. Make sure that the valves are fully open.
Sometimes if you get a new tank, you may find air in the lines. To remove that air, light your stove burners first to bleed the air out of the propane lines.
Blocked vents are a major issue. Mud daubers, wasps, or debris in the exterior exhaust or intake vent can stop the furnace from igniting. Make sure you clean them at least once a week so that they work seamlessly.
At times, your sail switch may also get blocked. If dust blocks it, the furnace will only blow air for 30 seconds before shutting down without any ignition. A sail switch is located in the duct where it overrides the gas valve of the burner.
Extreme carbon buildup can also prevent the sensor from detecting the flame. This leads to the system locking out after three ignition tries.
Your water heater or furnace is one of the most important parts of your RV adventures. You may want to manage its performance yourself if it doesn’t work properly. But in some instances, you should call an RV service in Cedar Park immediately.

Possible causes include low 12-volt power, insufficient propane, a blocked intake or exhaust, or a problem with the sail switch, igniter, or flame-sensing electrode. If the furnace cannot ignite or confirm a flame, it closes the propane valve and enters lockout.
Blocked return air or covered heat outlets can cause overheating and trip the high-limit switch. Repeated lockouts can also indicate low voltage, propane, sail-switch, or flame-sensing problems, so avoid continually resetting the furnace.
This code means the sail switch did not confirm adequate airflow or the high-limit switch opened because of overheating. Check for covered registers and blocked return, intake, or exhaust openings; have the furnace serviced if the fault continues.
Set the bypass valves to normal, fill the tank completely, connect the RV to 120-volt power, and turn on the water-heater breaker and electric switch. Never energize an empty tank, and reset the high-limit switch only as directed by your model’s manual.
Turning off the heater stops heating but does not stop water flow. If the tank is empty, the winterization bypass may be routing cold water directly into the hot-water lines; return the valves to normal and fill the tank before heating.
