When a furnace is working properly, the indoor temperature remains cozy and comfortable. It will keep operating in the background properly with no issues and no one will even notice. Even though furnaces are designed to have long and useful lives, there always is a slight chance that something might go wrong with them and give you heating trouble. Common furnace issues are minute and easy to fix but some may need special attention and a trained furnace repair technician.
Understanding the most common furnace issues may help prevent furnace issues from occurring. Some issues may be happening more often than others while some may just need a little troubleshooting on your part to get fixed instantly. But sometimes what may seem like a tiny or irrelevant recurring issue may be some major issue that might need a skilled technician. Let’s take a look at the most common furnace issues faced in most households.
1) The Thermostat Isn’t Functioning
One of the most common furnace issues faced in most households is a malfunctioning thermostat. A definitive sign of your thermostat not working as intended is if the fan is always running. This eventually leads to the batteries in the thermostat running out and causing home heating issues. A furnace repair technician will help you figure out how to fix the problem for good.
2) Dirty or Clogged Filters
This is a major issue that can reduce the efficiency of your furnace by reducing the intake that the furnace needs to function. It can also lead to potential damage to the limit switch. Depending on your home (IE: pets, allergies, etc.) filters should be swapped out monthly, every other month, or quarterly to ensure no home heating issues and peak performance.
3) Cracked Heat Exchanger
This is an issue that requires a furnace repair expert and is quite costly. This damage is done if the air filter is not replaced in time or due to the overheating of your home. A furnace repair technician will diagnose the issue correctly and replace the heat exchanger for better functioning.
4) Frayed or Malfunctioning Blower Belt
The blower belt is a part of the motor that assists the furnace fan in running properly. These will occasionally or over time start to break or fray and it can be determined by a squealing high-pitched sound when the furnace is running. This belt needs to be replaced to improve the performance and efficiency of the fan.
5) Malfunction of the Limit Switch
A limit switch malfunction leads to the furnace blowing continuously, even when it shouldn’t. This part should be replaced by a furnace repair technician if the problem occurs.
6) Worn Out Ball Bearings
Ball bearings are a part that helps the motor of the furnace work properly. It is one of the common furnace issues for them to burn out and they can be fixed only through replacement. An issue in the ball bearings can be made out by a scraping sound.
