As a responsible homeowner interested in keeping their appliance in top shape, you might wonder what fails more often so you can keep a close eye on it, right? Well, plenty of things can go wrong with the furnace. Here are some common areas that can fail, as given by furnace service professionals.
The thermostat is responsible for controlling the temperature of your furnace, and it works by measuring the temperature of the air in your house and compares it to the temperature you have set on the thermostat.

Like any appliance in the house, the thermostat is prone to several problems. One of the problems is the wiring problem. The wires can be old and damaged by animals, among many other issues. As you can guess, when your unit has wiring problems, there is no way it will accurately control the temperature in your house.
The thermostat can also have battery issues. Battery problems are often the leading causes of the thermostat not working, and the most common one is the battery dying due to constant use. When you notice your thermostat not working, you should check the batteries as they might be worn out and need replacement.
Other parts of the furnace, such as the display or sensor, might also stop working due to abuse or old age.
