You rely on your furnace to keep your home warm and comfortable as winter approaches. When your unit keeps shutting off, it leaves you and the members of your household feeling frustrated and chilly! Let’s take a look at five reasons why this might be happening.
1. Faulty Thermostat
Your thermostat sends signals to the furnace based on your interior temperature. If your thermostat isn’t reading the temperature accurately, the furnace may shut down. If you suspect a faulty thermostat, check whether the batteries need to be charged or replaced. In addition, remember that if your thermostat is near a heat source, it will assume the entire building is warm.
2. Dirty Air Vents and Filters
Accumulation of dirt and debris in the filters and vents restricts airflow throughout your home. As a result, your furnace will strain to pass air and might overheat. When this occurs, the furnace may shut down as a safety mechanism. Experts recommend that most homeowners change their furnace filters every three months.
3. Low Gas Supply
The furnace will automatically turn off when it does not receive adequate fuel. Reduced gas supply may be due to low gas pressure or gas leakage. For safety reasons, contact an HVAC professional if you suspect gas supply issues with your furnace.
4. Ductwork Problems
Incorrect ductwork sizing leads to uneven heat distribution. Some rooms will reach the thermostat’s set temperature, while others won’t receive adequate heat. Ductwork leaks also result in warm air loss, causing some rooms to warm up before others.
5. Faulty Flame Sensor
The flame sensor is a safety feature that detects the presence of a pilot light when the furnace is running and signals the gas valve to open. If it is dirty or faulty, the gas valve may close and shut down the furnace.
