Dealing with Common Furnace Issues: A Troubleshooting Guide

Dealing with Common Furnace Issues: A Troubleshooting GuideWhen you turn on your furnace for the first time during a new heating season, you may encounter some problems that keep it from working properly. Here are some troubleshooting tips for several common furnace problems that you may be able to take care of without needing to call for professional assistance.

Power Problems

  • Check the furnace’s electrical connections to make sure it is properly hooked up to a power source and is receiving electricity.
  • Ensure the power switch on the furnace itself is switched to the “on” position.
  • Make sure the circuit breaker controlling the furnace hasn’t tripped. Reset the breaker if necessary. If the breaker keeps tripping, call for professional assistance as there might be a serious electrical problem.

Furnace Not Starting

  • Check programmable thermostats to ensure they are working properly and that they are receiving power. Put in new batteries if needed.
  • Look for the pilot light and make sure it is lit. If it’s out and as long as you’re comfortable doing so, re-light the pilot light, or get an HVAC professional to help you with this.
  • Make sure electronic ignition systems are working properly.

Heat Problems

  • Check the thermostat make sure it has been set to the “heating” function.
  • Ensure the thermostat settings are at a level appropriate to the outdoor temperatures. Shift settings up a few degrees to see if that causes the furnace to start.

Airflow Problems

  • Make sure the furnace’s air filters are not clogged or dirty. Put in new filters to ensure proper airflow. This will also improve overall indoor air quality throughout your living spaces. Dirty air filters are one of the most common causes of furnace malfunctions and can even cause damage to the system.
  • Check supply vents and air return registers to make sure they aren’t blocked by furniture, boxes, or other objects. Make sure any dampers at vents haven’t been closed and that duct pipes are tightly connected to supply vents.
