5 Problems You Can Expect From Furnaces

A faulty furnace can make your home very uncomfortable and even risky if young children or seniors are in the house. Furnaces can develop problems just like any other appliance. However, it is possible to prevent costly and extensive damage with preventative maintenance. Regular diagnosis and testing of different components can reveal emerging problems and fix them before they cause complete failure. So, what are some of the most common problems with furnaces? 

1. Faulty Ignition or Pilot Light: 

A faulty pilot light can cause the furnace to turn on and off frequently and cause the temperature in the house to drop. Pilot lights are either turned on manually or lit automatically with a thermocouple. If there is a problem with the thermocouple, it will need to be replaced. 

A faulty electric igniter can cause the heater to fail. You need professional furnace repair services to repair a faulty ignition or pilot light. 

2. Slipped or Frayed Blower Belt: 

A slipped belt can make the furnace very noisy. You will hear a loud squealing noise when the blower belt is faulty. In this case, you will need to hire furnace repair services to replace the blower belt with a new one. 

3. Worn-Out Ball Bearings: 

You will hear loud scraping sounds from the furnace if the ball bearings are worn out. You need to switch off the furnace to prevent more extensive damage, and you should call residential heating repair services before switching on the furnace again. 

4. Faulty Limit Switch: 

Furnace limit switches are designed to shut down the furnace if there is a problem with the airflow or if there is a fire. If the limit switch fails, it will not shut down the furnace when a problem is detected. This could lead to extensive damage, including cracked heat exchanger pipes. Also, the furnace will blow continuously, which could be a fire hazard. Call furnace repair services immediately to keep your family safe if you notice this occurring. 

5. Faulty Thermostat: 

The thermostat is responsible for bringing the furnace to the desired temperature. If a thermostat fails, the furnace may turn on and off frequently, causing irregular temperatures. 

Frequent cycling makes the furnace consume more power than necessary, raising your power bills. It will also make the house uncomfortably hot or cold. If a thermostat is faulty, it will need testing and replacement by a competent technician.
