RV Furnace Repair Basics

RV furnace repair is not difficult. Having a furnace is a very beneficial feature to have in an RV. Even a small camera can also have this feature. This is not a luxury and not used for heating. These machines are commonly installed for its heating purposes, and are used during cold seasons or winters. Just like your furnaces at home, RV furnaces can also encounter some mechanical issues that may need troubleshooting. As impossible as it may sound, you do not need a pro to fix this problem for you. Listed below are some repair basics that can be helpful to you.

Pilot Light

Sometimes you may notice that the pilot lights do not light up. Take a look at the propane tank and make sure that it is turned on and not unfilled. If by any chance that this is not the issue, turn on the stove burner and observe the color of the fire. The color of the flame should be in blue with a little bit of yellow. It should not be completely yellow. If the flame color is consistent, this means that your device is working just fine. If your regulator is not functioning right, this can affect your hot water heater. Check the thermocouple and it should be 1/8 far from the pilot lights. Make sure that there is no spider nest in the vent as this can obstruct the ventilation of the machine.

Fan Does Not Run but Have Heat

If you notice that your machine is producing heat but the fan is not running, this means that you have gas or this issue started due to several factors. First, check the batteries. Make sure that the batteries are correctly charged. If it is, then take a look at the circuit breaker. Ensure that the breakers are not blown or flipped off. If not, check the settings of the thermostat. If it is set correctly, you will need to replace it with a new one.

Fan Does Not Work and Produces No Heat

In this case, you need to make sure that the batteries are still full and you have twelve volts at the heater. The machine may have a blown fuse or a loosen circuit breaker. Next, take a look at the thermostat if there is electricity to the RV’s heater and the battery is good. Take off the cover and locate the anticipator regulators. Some thermostat does not have this feature. It looks like a regulator with a sliding contact over a straight plain cable or a plain wire wound about a protecting material. If by any chance that the vent is still not working, regulate the temperature to maximum. Interchange the anticipator slide while waiting for the fan to function. It may not start instantly. It usually takes thirty second for the thermostat to send signal in order for the fan to start running.

If the fan begins to run after interchanging the slide, then you have discovered the problem. For this situation, you may need to look for a slider located close to the original position that will function consistently. If the regulators has the straight cable and the cable lies straight to the plastic housing, this means that the wire is producing heat which can melt the plastic which causes the cable to sink into the plastic which obstructs the slider. In this case, you need to replace the thermostat.

Fan Is Running but Produces No Heat

This machine has an interior navigator switch that senses the flow of the air. If by any chance the air that flows to the furnace is not enough, it will obstruct the furnace from heating and the vent will work but will not produce heat. A sluggish motor speed can be caused by a bad battery of other low voltage caused by bad cabling connection.

Insufficient air flow can also be triggered by a poor airing system. It is essential to check if the heat registers are closed or obstructed. Some furnaces can experience problems even with a small blockage of a heat register.

If you are using furnaces with electronic heating system, you must check if the two contacts are connecting. These contacts should be about 1/8 apart.
