Is Your Furnace Not Blowing Air?

OMG, the blower is not blowing air! But the furnace motor is on! What has gone wrong with the blower? Was this your reaction after you noticed the problem? We advise you to calm down because the problem is not as big as it seems, and you can easily fix it. The blower has failed to work because the belt connecting the two has probably broken. Turn off the power and gas supply. Now, remove the front door of your furnace cabinet to get access to the blower. See the number mentioned on the belt, go to your favorite hardware store and buy the belt with the same number for your furnace.

Now the real challenge is before you – how to remove the broken belt and attach the new one correctly. Let’s first talk about how you will remove the broken belt.

Loosen the bolts carefully with your wrench to move motor slightly in the direction of the blower. Now, move it gently towards the blower so that the belt slacks a bit. Now, pull the broken belt off.

When it comes to attaching the new belt, first, check for any debris in the area for the belt and remove it properly. Next, place the new belt on the pulleys of the motor, then on the blower. Now, place the motor back in its proper place and bolt it down safely. You should oil the motor as well as the fans. Also, oil the sealed bearings if mentioned in the manual. You are done.

An important point to consider here is that your blower may run continuously for two reasons – one, the room thermostat or the limit switch given below the plenum on your furnace. The limit switch gets automatically switched off after the air in the plenum becomes too hot. You should check the thermostat to see whether the fan switch is switched off or on. If it is on, turn it to off or auto.

However, the limit switch will  need to be adjusted that is something you cannot do yourself. You will need help from an expert in furnace repair in Coquitlam.
