How to Fix Your Furnace's Blower That Won't Turn Off
Every winter brings with it some extra maintenance work for homeowners—and a furnace blower that won't turn off is an especially frustrating problem. It's uncomfortable, it wastes energy, and it may even be dangerous if it runs too long or too hot.
Fortunately, there is usually a straightforward solution to this issue. By understanding some basic principles of furnace repair, you can save money, reduce potential fire risks, and live in comfort once more.
Furnace Blower Constantly Running: Understanding the Basics
A furnace operates by cycling heat through a system of ducts and vents, using a blower motor to pull in and out of the space. This cycle is controlled by a thermostat, with the goal of maintaining a steady temperature.
The blower motor runs in both heating and cooling modes. If the motor starts to stay on even when the system is turned off, it could mean a few different things.
First, it could be that the blower motor itself has a malfunction and needs to be replaced. It could also be due to the limit switch, which is the part of the furnace that shuts off the blower once a certain temperature is reached. This limits the amount of heat that is in the home and also prevents the motor from running too long and burning itself out.
Another possibility is a faulty thermostat. The thermostat sends signals to the furnace when to kick on and off, depending on the temperature of the room. If the thermostat is inaccurate or malfunctioning, then it could keep the motor running even when the space has reached the desired temperature.
Troubleshooting the Problem
The first step to troubleshooting a furnace blower that isn't shutting off is checking the limit switch. This unit is normally located near the lower portion of the furnace and should have an accompanying label that tells you when it should turn off the blower.
If the readings match what's written on the label, then the issue likely isn't with the limit switch. If they don't match, you can try adjusting the switch to the specified shut-off point.
If that doesn't resolve the issue, then try inspecting the thermostat. Take it off the wall and check the batteries, as well as the wiring in the unit. The wiring should be snugly connected, and the batteries should have a full charge.
You can also try resetting the thermostat, as this can sometimes throw off the accuracy.
Seeking Professional Assistance
If these steps don't result in the blower motor turning off, then it's likely a more serious repair job. In these cases, it's best to seek professional help. Faulty wiring or a damaged motor can be a potential fire hazard and should only be replaced by a qualified technician.
When looking for a reliable furnace repair specialist, make sure to choose one with a good credible background. Ask for references and see if they include customers from your area. Also, ask whether they guarantee their services and what sort of parts they use. The last thing you want is to have your repair fail after a month or so.
Finally, make sure to use only certified technicians and licensed contractors to ensure that your furnace is being serviced correctly and using quality parts.
Conclusion
When your furnace's blower won't turn off, it can be both an uncomfortable and dangerous situation. Fortunately, most of the time the issue can be fairly easily fixed by a few simple troubleshooting steps and minor repairs.
If the issue is more serious and requires the services of a professional, make sure to research the technician and make sure they are certified. This will guarantee that the repair is correct and completed safely.
