2 Problems That Can Cause Your Furnace To Stop Working

As temperatures cool down, you'll be getting ready to start turning on your furnace to heat up your home. Unfortunately, your furnace that was working great last winter may start to malfunction when you are ready to use it again. Here are a few common reasons that could cause your home's furnace to stop working.

Broken Thermostat

The thermostat is often to blame for a malfunctioning furnace. The problem could be as simple as not having working batteries in the thermostat, causing it to appear as if the digital panel will not turn on. Try swapping out the batteries and see if that does the trick.

If the batteries are working, the issue could be caused by the wire that travels from your thermostat to the furnace. All it takes is a pest, such as a small mouse, to chew through this wire during the fall to cause the thermostat to stop working in the winter. You may need the help of an HVAC professional to test and run a new wire from your thermostat to the HVAC system.

Broken Blower Fan

The furnace itself can be producing all the heat you need, but it won't make its way through your home if your blower motor isn't operating properly. This is what pushes the air through the vents, and it is a crucial part to the system's operation, even though it is not producing any heat.

There are a couple common issues with the blower motor. For starters, the motor itself may be broken. This is going to be a more costly repair, since you will most likely need to have the entire motor replaced with a new one. The problem could also be as simple as a broken belt, which is what turns the fan blades that push the air through your home.

Diagnosing a broken blower motor will be the hardest part of solving this problem, but a broken belt is easy to repair on your own.

These are just a few reasons that your furnace can stop working. Other problems, such as a broken heat exchanger or heating element, will often require the help of a professional to repair. Consider calling a technician for heating repair services and getting an annual inspection of your HVAC system done to prevent problems before they occur. Making sure your furnace is up to snuff will help keep the heat running during the winter.

cool and hot areas of the home

I live in an older home that we are working to renovate. There are three areas of the house that just don't seem to get cool in the summer or get warm in the winter. I have done all that I can to try to keep these areas comfortable, but I wasn't able to do much until I hired an HVAC technician to come out and figure out why those areas were so uncomfortable. This blog will show you what can be causing areas of your home to be less comfortable than other areas when it comes to temperature during both winter and summer.
