Call A Residential Heater Repair Company For Help When Your Furnace Starts Making Scraping Noises
If your furnace suddenly starts making a scraping noise, you should call a residential heater repair company and let them know. They may say to shut your furnace down until a repair technician can assess the problem.
Since the blower in your furnace is a part that turns when your furnace kicks on, it's a likely part to consider when you hear scraping. Here's why your blower might make the odd noise and what a residential heater repair technician might need to do to fix the problem.
Why A Blower Can Make Odd Noises
When your furnace kicks on, the blower starts spinning. That creates vibrations that might cause the screws to back out or the blower to work loose over time. If the blower isn't held in place securely, it might scrape against the metal part of the furnace housing when it spins. This creates a scraping noise.
It's also possible a part that holds the blower or motor in place has broken. The blower itself might even be broken or have something stuck in the fins that is scraping against the furnace as the wheel spins.
How The Problem Can Be Identified
A heater repair technician can remove the furnace cover and pull the blower out to be examined closely. Once the blower is out, the technician can clean the fins to get rid of dust and debris. The fins should be cleaned when you have a furnace check-up, but if they are dusty or have something stuck in them, the technician may take time to clean them again.
When the blower is out and cleaned, the technician can check for broken parts. If everything is okay, the technician can put the blower back in its place and tighten all the screws, brackets, and other parts to make sure nothing is loose enough to allow the blower to move out of alignment or scrape against metal inside the furnace.
While this may not seem like a very serious furnace problem, a blower that is out of alignment can cause a lot of problems. If the blower makes the motor strain, the motor could burn out. Plus, if the blower is out of alignment, parts might be damaged. These problems could lead to more expensive repairs.
That's why it's a good idea to shut off your furnace and call a residential heater repair company when your furnace makes unusual noises. Scraping sounds are just one type of noise you could hear, and when you hear a new sound, you may not have any idea what it means. That's why getting professional help is such a good idea. The technician will identify the cause of the sound and find a way to stop it before harm comes to your furnace.
