Getting rid of debris

An RV furnace is notoriously noisy. This is largely because they have a lot of moving parts, a high-speed fan, and cracks or orifices where dirt and debris can get stuck. Most of the noise comes from this high-speed fan and the enclosure that contains it. If you want to make your RV furnace quieter, follow the steps outlined below. You will need an aerosol can of dust blower, a wire brush, and degreaser.

If you notice that your RV furnace makes a lot of noise, it’s possible that there’s a problem with the air register. Make sure the air register is free of debris, which can cause the fan to rattle. To fix this, you can install soundproofing in the air register. You can also clean the exhaust pipe, which is notorious for being a warm spot for critters. Getting rid of the debris will quiet the venting and help keep your furnace running at its highest efficiency.

Installing soundproofing material

If you’ve ever had a noisy RV, you may be wondering how to make it quieter. Well, there are several ways to do this. One of the easiest ways is to use soundproofing material. Mass Loaded Vinyl is a great option, but you can also use spray adhesive. Green Glue is a common option, because it’s effective at blocking impact noise. Some soundproofing experts even recommend that you use it to create acoustically-deadening wall for your RV. You can also install FatMat, which has a sticky side.

Another effective method is to install insulation to the floor of your RV. RV furnaces are loud, so installing soundproofing material on the floor can help you sleep well. You can also use heat shield material on your windows to reduce noise. To add even more soundproofing to your RV, you can use Soundproof Cow’s Vibra Block(r) Sound-Deadening Material. You can also use fiberglass, a non-combustible material that can be purchased from a building supply distributor or a big box store.

Cleaning clogged vents

If you’ve tried blowing out the vents, but the noise still persists, there may be a leak somewhere. If you see a sooty streak on the exhaust vent, stop using the furnace immediately and call a professional. Continued use could cause a fire or injury in the RV. Other potential problems include a clogged vent, low gas pressure, and a broken fan motor.

Before you start using your RV furnace, make sure you clean the vents regularly. You should vacuum the ducts at least once a season, and ideally before you first use it. This prevents the ducts from becoming clogged with dirt. Regular use of your RV can also contribute to dirt and debris that build up inside them. Be sure to check air outlet vents as well to ensure they aren’t plugged.

Cleaning ignitor

Before you begin cleaning the ignitor, you need to ensure that the probe is not cracked or dirty. You can use a fine steel wool or emery cloth to clean this part. Make sure that the probe is clean before applying oil or cleaning solution to it. If you are cleaning the probe physically, follow these instructions to keep the unit quiet. If you are cleaning the probe of an older model, be careful not to rub too hard because it could damage the ignitor.

If the ignitor is dirty, it will prevent the air from passing through the furnace properly. If this problem persists, consider cleaning the ignitor. It is easy and inexpensive to replace the ignitor, so it is well worth the effort. Once it is cleaned, your furnace should run quietly and efficiently. However, if this still does not solve the problem, you might need to replace it.

Cleaning ducts

Clean out your RV’s ducts to keep your furnace quiet. You can use a shop vac to remove debris from the ductwork. Check ducts for box elder bugs and stink bugs. If they’re still present, they might be wintering in your ductwork. To eliminate stink bugs, clean out ducts regularly. Also, check seals, screens, and caulk around the furnace.

If your RV’s ducts are wall-ducted, you can clean them with a vacuum cleaner to eliminate dust and debris from the vents. Be sure to check air outlet vents, too. If you notice any obstructions, clean them out right away. Next, check ducts for tears and kinks. You should also check for excessive bends and tears. Inspect ducts for debris to prevent noise and poor efficiency.

Changing motor

A loud squealing noise is probably coming from your RV furnace. This noise could be caused by a number of problems. The blower motor or fan motor may be defective or loose. In the case of the fan motor, try tightening the motor wheel to stop it from squealing. If the fan is loose, the wheel can be removed and tightened. In addition, it may be causing the noise by overheating. If you are unable to identify the cause, you may want to replace the blower motor and the fan.

There are many ways to replace the blower motor on an RV furnace. Many are simple to install. Depending on the model, you can change the motor yourself. This option should cost around $50 or more. Purchasing a new blower motor online or at an RV store may save you a lot of time and money. Alternatively, you may want to hire a professional to replace the blower motor.
