Where Is The Reset Button On A RV Furnace? - The RV Blogger (2023)

If you have recently had issues with your RV’s electrical, or your breaker has been tripping, you may need to reset your furnace. However, sometimes it can be hard to identify this button depending on the make and model of your specific furnace. Thankfully, most RV furnaces are very simple and aren’t extremely complicated to use. Most furnaces you will find in your camper will have two blower motors inside, one for combustion and the other for circulation. Usually, you will find your RV furnace’s reset button on the very inside of the blower compartment where these motors are located.

In some cases, completely resetting your furnace may not be needed. Like mentioned before, you may be wanting to reset your furnace because something keeps tripping or because your furnace fan has stopped/is failing to blow. However, resetting may not always be what needs to happen in these cases. You should first try turning off the furnace and turning it on again. It may just be that a minor trip in electricity has caused it to stop working temporarily, and doesn’t need an entire reset.

Another solution may be that your furnace’s blower motors are either damaged or broken. In this case, resetting won’t solve the problem, as the motors will need to be replaced, if not your entire unit. It may also be that something has come loose (such as nuts and bolts or a squirrel cage) or that a bearing has gone dry. These are all things you should try and remember to check routinely so that you don’t encounter emergency situations. Motor bearings need to be greased with oil every once and a while, as they are known to cause problems when they go dry. You should try and regrease them at least once a year, perhaps when you are winterizing.

If your furnace has stopped working altogether, and you have determined it isn’t because of any of the issues discussed above, then you will want to start a series of troubleshooting methods. First, you will want to check and make sure that your batteries are even sending power to your furnace in the first place. It is common to assume immediately there is a problem with your furnace, but batteries often have problems, meaning they could likely be the reason you aren’t getting any heat from your RV’s furnace.

Check your RV’s batteries to see if they are low in battery or haven’t been charging properly in the first place. You may want to try using a completely different battery (that is fully charged) to test and see if your problem is really with your furnace or power source. If you have had a power surge or problems with your electrical, it could be that a surge has damaged your batteries. This could potentially lead to problems with anything that your batteries provide power for. You should be able to tell if your batteries have been damaged from a power surge by using a multimeter to see what kind of power is coming from the battery. A furnace requires 12 volts of power, much like other battery-powered items around your camper.

Obviously, another troubleshooting step that should be taken, is checking your breath box to see if any fuses have blown. This is actually a common problem that can happen from old or damaged electrical, or from a surge of lighting from a storm. If the fuse for either your furnace or batteries has been blown, this is likely your problem. You will need to replace the fuse as well as any damage the surge has caused. When dealing with electrical, you will need to keep in mind that since many things are all connected together, sometimes several components will need to be replaced as an effect of that.

Sometimes the only problem with your RV furnace is that it needs to be cleaned. In residential homes, furnaces have filters to keep the air clean and prevent harmful dust and dirt from building up inside the furnace itself. However, most RV furnaces don’t come with filters, as this is something you will have to install if you want it. If you have not placed a filter in your furnace, there is likely a large build-up of dirt, dust, and debris. This will need to be cleaned out, as it has likely made its way through your fans and has caked many surfaces. If it has been several years since any cleaning was done, the dust has likely made its way to your RV’s exhaust fan as well.

In order to prevent this from happening in the future, you will need to make or purchase a filter for your furnace. You can make your own with felt or cutting an existing one to size. In most cases, you probably won’t be able to just use a residential filter, so making your own will be necessary. You should change out your filter every 3 to 6 months, depending on how much dust builds up, as well as how often you use your RV in the first place.

Why Is My RV Furance Reset Button Tripping?

A common problem that RV owners have encountered with their furnace, is the reset button constantly tripping. This can be very frustrating, especially if you like to travel during the colder months. There are actually many reasons your furnace’s reset button is tripping, as electrical can be tricky to deal with. Let’s take a look at some of the most common reasons your RV’s furnace may be tripping, and you how can prevent this from happening in the future:

  • Blocked valves. Valves are very important for your furnace, as air curculation is how everything functions and keeps working properly. Sometimes valves can get clogged with dirt, dust, or debris. It is very important that your furnace stays clean of any kind of blockage, as clogging can lead to overheating, which will lead to problems such as the one we are discussing in this article. You should make an effort to clean out your furnace’s valves at least once a year, depending on how often your camper gets taken out.
  • Overheating. Overheating can start in a few different ways, but it is not ideal for the condition of your furnace. Overheating can lead to your reset button tripping, as well as many other problems with your furnace. Sometimes blockage in your valves will lead to overheating, or getting any airflow in general. Like mentioned before, keeping your RV furnace clean is very important to keep things from overheating.
  • Low gas or fuel. Sometimes when your reset button keeps tripping, is it becuase you are low on gas or fuel. If possible you should avoid ever letting your gas tank go dry, because it can lead to eletcircal trouble. You should keep a close eye on the elevel of fuel you have and refuel as soon as possible to avoid tripping.
