If your heater suddenly breaks down on a cold night and you’re clueless as to what caused the problem, it’s not a pleasant experience. Though you could make an emergency call to a heating contractor, they could be busy helping other customers with similar heating issues, leaving you to wait in the cold. Knowing the common causes of a furnace breakdown can help you solve the problem or avoid it altogether with a proactive tuneup.

Reasons Why Heaters Stop Working

1. Power Supply Issues

Heating systems often stop working when there’s a problem with the power source. If your furnace stalls, check the power supply before calling your heating contractor. Make sure the unit’s properly plugged in, then check the switch and fuse for any issues and reset or replace them if necessary.

2. Deficient Maintenance

To keep your furnace running smoothly, it’s best to schedule an inspection and maintenance check every fall. Skipping this task can cause dirt to build up inside your heater, which may compromise its efficiency.

For instance, grimy filters restrict airflow or carry contaminants throughout your system. Dirt can also accumulate and interfere with your flame sensor until it fails to register the heat and starts turning off right after it turns on.

3. Incorrect Calibration

Proper calibration will keep your unit from working harder than it should, which can increase your gas consumption. This is also important to prevent overheating.

To verify if your unit is calibrated correctly, turn off the heater for at least 30 minutes. Reset it before turning it on again. If you feel hesitant to recalibrate the device, ask a heating contractor to walk you through this process.
