Just like any system, a furnace can experience failures during its lifetime. The cause of failure could be for a plethora of reasons, many being out of your control. But sometimes issues occur due to poor care such as lack of maintenance, system neglect, and ignoring any warning signs. Here are the top four causes of furnace failure.

Clogged Filters
Clogged filters are one of the most common issues when it comes to furnace failure. When homeowners forget to change their air filter or underestimate the replacement time, dust and dirt can build up which results in a clogged filter. A clogged filter can lead to a furnace that overworks itself. Set yourself a consistent reminder to change your air filter every 30-90 days. Factors such as allergies, asthma, and pets require a filter to be changed more frequently.

Dirty Flame Sensor
Your furnace has a certain safety component that helps the system determine the consistency of the furnace flame as well as any potential issues. This component is known as a flame sensor. If the flame sensor gets dirty it can cause the furnace to malfunction. Since this component is quite delicate, it is best to have a certified HVAC specialist repair the issue.

Failed Circuit Board
The circuit board is in charge of communicating to the furnace how to function. A circuit board that is damaged may result is a furnace that fails. Some common issues that can occur with a circuit board include dirt build up, water damage, and surges. Have a professional inspect your circuit board if you suspect any damage.

Broken Blower Motor
The blower motor is responsible for moving heat throughout the home. If your furnace is running but not providing any heat through your home, this may be a sign that the blower motor is broken. Schedule a furnace repair appointment with a certified technician in the Greater Toronto Area.
