![]() ![]() Maybe it’s rusted, or there could be an insect nest somewhere inside of it. ![]() However, the sail switch itself can be the cause of this issue. A weak power source won’t trigger the sail switch, and it won’t regulate the air flow. Once again, the low battery voltage can be the issue here, so the best thing to do is to replace the battery. After all, a furnace shouldn’t be blowing cold air, right? People get confused, and sometimes even scared when this happens. Even a small blockage can obstruct the air flow, so doing this properly is important. If this is the case, I clean up all of the heat registers. However, a different problem might be insufficient ventilation. No electricity results in less force to ignite the sail switch. The first thing I suggest be done here is to check for batteries or poor electrical connections to the motor of the blower. There will be times when the furnace fan clearly works but no heat comes from it. ![]() I’ve heard people have this problem plenty of times in the past. If it happens to be low power, I merely replace the battery with a one that has the right voltage. RV Furnace Blower Comes on but Won’t IgniteĪnother common issue is when the blower begins to blow, but the furnace still isn’t igniting. Thermocouples for RVs aren’t expensive, and anyone can replace them. In case it’s broken or damaged, I buy a new one and replace it. However, if that’s not the problem, I take a look at the thermocouple. If not, I refill the tank as soon as I can. First, I check if I have any propane left. The furnace not igniting can happen because of several reasons, so whenever I have an issue like this, I follow a few steps. This is a fairly common problem every RVer faces. Of course, any foul smells usually indicate problems with the furnace as well.Įach of these problems has a suitable solution, some of which even the owner can apply without the aid of an expert. Then there are various noise-related problems, such as clicking, humming or squealing. Other times, the furnace won’t switch off. Some of them relate to the furnace not igniting, even if other elements are working fine (such as the fan). Most of the problems will get addressed here, but I’ll summarize them nonetheless. For maximum effect, a few strategic drops of oil will suffice. Most people make the mistake of pouring too much oil on, “drowning” the bearings in it. However, there’s the question of how to lubricate them. This can be caused by motor bearings, and the quickest solution is lubrication. One of the issues that will pop up in this text deals with noise, specifically squealing. In addition, if the furnace “slides” about, it might be a good idea to harness it with something, like screws. If not, they can cause lots of problems in the future. It’s important to connect the gas line, the wiring, and the vents properly and securely. How to Install an RV FurnaceĬonsidering that the installation of an RV furnace is almost the exact opposite of its removal, I won’t repeat the steps in too much detail. I then unscrew any section of the furnace that’s screwed to the base and I can slide it out with no issues. These wires might even have to be cut and reconnected later. Next, I disconnect the gas line, the vents and any wiring connecting it to the thermostat and other gadgets. First, I must make sure everything related to the furnace is turned off since I don’t want to be shocked by electricity. There are several key steps I should do before I can remove my furnace. However, I shouldn’t have to point out to only do that when the furnace is cold, i.e. With modern RVs, removing the furnace is easy. Airflow is very important, and a thick filter can do more harm than good. It’s important to note here that, should anyone install a filter on their RV furnace, they have to pay attention to how restrictive it is, or rather - isn’t. Usually, they don’t, but filters can be added if an owner feels inclined to do so. In addition, it’s easier to access and perform repairs from its position. Most of the ducts that run from the furnace run from the bottom through the entire RV, heating it up evenly. It’s not a coincidence that the furnace is where it is. I can usually tell what the furnace looks like and where it is based on the outside vents. With most RVs, the furnace is located on the lower side of an RV. The Ins and Outs of an RV Furnace Where Is the RV Furnace Located? Having a functioning one inside the RV is extremely important, and sometimes even the smallest glitches can cause huge issues. Each RV comes with furnaces of different sizes, types, and capabilities. As its name suggests, it’s a propane-powered furnace for the motorhome.
