Your RV furnace might be making a lot of noise. To help quiet it down, make sure the air register is clean and free from debris. Also, make sure the fan is clean and free of loose parts. If that doesn’t solve the problem, you can install soundproofing in the air register to reduce the noise.
Older furnaces tend to be louder
Older RV furnaces tend to be loud, and there are several causes for this. First, the metal housing plate may be loose. This causes the fan to scrape against the housing and produce a squealing noise. Another potential cause is a loose metal retaining clip. The loose clip may cause the exhaust wheel to move inwards, causing it to come into contact with the housing.
A dirty filter can also cause an RV furnace to be noisy. A clogged filter will block the airflow and make it difficult to run efficiently. You should also clean the vents and ducts on your RV furnace to eliminate dust and dirt. In addition, you should wipe down the fan blades. If they are dirty, they will become heavier and make a noise.
Lastly, the exhaust pipe is another potential cause of noise. An older RV furnace is likely to be louder than a new one. Its exhaust pipe may be clogged, resulting in black smoke. Additionally, the exhaust hole may be blocked, resulting in a foul odor. This odor doesn’t smell good at all and should set off alarms for you.
Metal air ducts
RV furnaces are notoriously noisy because of the many moving parts. There are often cracks and loose components. The metal in the air ducts can also expand and contract, resulting in loud noises. A loud noise usually means a metal air duct is either undersized or flimsy. You should check the vents and air filter to determine if these factors are the culprits.
To reduce the noise produced by your furnace, clean the ducts. Do this at least once a season or before first use. During the normal use of your RV, dust and dirt will accumulate in the ducts. By vacuuming the ducts, you will remove any extra weight and help the fan run more efficiently. You should also check air outlet vents for any dirt and debris.
If you can’t solve the problem yourself, consult a duct specialist. They will recommend an alternative solution based on your specific circumstances. A good way to find out if your RV furnace is too loud is to check the metal air ducts. If they are not properly secured, hot air can leak through the air ducts and cause the noise.
Heat exchanger
If your RV furnace is making a lot of noise, you may want to try troubleshooting. The noise could be coming from the pilot light or the fan. If you hear any strange noises, you should contact a professional to come check it out. You may find more issues than you think.
One cause of the noise could be a clogged vent. This can restrict airflow to the furnace and reduce its efficiency. The furnace vent should be clean and free of debris. Make sure the outlet is clear as well. Often times, an RV furnace does not come with a filter, but you can purchase a new one from an RV parts store.
The noise could also be coming from the blower motor. Sometimes, the blower motor may have a bad bearing and needs to be replaced. If this is the case, try applying oil or grease to the bearings. A new blower motor is fairly inexpensive to replace and should not cost much.
Gas problem
If your RV furnace isn’t producing hot air, you might have a gas problem. While you can try to troubleshoot it yourself, it can be time-consuming and frustrating. If you can’t solve the problem yourself, you might need to replace the unit. However, before you throw in the towel, you can try these tips.
First, check the voltage. Make sure you are getting at least 10 volts. You may be able to test the voltage with a digital multimeter. Make sure the test leads are plugged into the corresponding wire connectors. If you’re confident with electronics, you can move on to troubleshooting the control module board.
If the vents are blocked, this could also cause the furnace to shut off suddenly. Another common cause is a faulty thermostat. If the thermostat is malfunctioning, you may need to replace the unit.
