Diagnosis 7 Common Heater Issues

You can easily and quickly diagnose common furnace issues based on the “symptoms” your heater system is exhibiting.

Common heater issues you may encounter include:

  1. The thermostat is not working. A clear sign that your thermostat is not working is if your fan is constantly running. This causes the thermostat to run constantly, causing inefficient thermostat function. You can diagnose this by setting your fan to auto and monitoring if it is running at your set heater temperatures.
  2. Dirty or clogged filters. If your filters are clogged and dirty, your furnace intake will be compromised. Airflow may be inadequate, making your furnace work harder to circulate. This can also cause damage to your limit switch, which controls your fans. To help prevent this issue, change or clean your filters every three months to be sure airflow is optimal.
  3. Pilot light issue. If your pilot light is flickering, weak, or yellow in color, it may indicate excessive carbon monoxide in your furnace. A pilot light repair requires an HVAC professional repair team as it may be due to a faulty ignition, thermocouple problem, drafts, or clogs.
  4. Cracked or damaged heat exchanger. Your heat exchanger separates the flame from the air, maintaining the safety of a running furnace. Heat exchanger cracks may be due to air filter clogs or overheating in your home.
  5. Frayed or damaged blower belt. The blower belt is part of your furnace’s motor. A malfunctioning blower belt may be indicated by a high-pitched squealing sound while the furnace is running. Keeping the blower belt well-maintained increases efficiency and performance.
  6. Limit switch malfunction. Limit switch malfunction can be indicated by a furnace continually blowing, regardless of the temperature settings.
  7. Zero airflow. If your furnace is not blowing air, it could be due to a clogged blower. Keeping the blower clear of dust, dirt, and debris will help to keep the air blowing.
