When you live in a place with severe winters like Lake County, a furnace that won’t produce heat is more than just an inconvenience. It’s a serious problem that demands immediate attention. Here are some of the most common reasons why a heater stops working and how to resolve them.

Check the Settings

Whether by a bump of the elbow or a spurt of energetic dusting, it’s easy to inadvertently alter the settings on your thermostat or heater without knowing it. Reset the thermostat, and then wait a couple of minutes for the system to start up:

  • Make sure that the switch on the thermostat is set to “Heat.”
  • Turn the fan setting on the thermostat from “Auto” to “On.”
  • Check the power switch located on or near the heater to ensure it’s in the “On” position.
  • Inspect your circuit breaker to verify that your heater is getting electrical power.

More Diagnostic Tips

A simple filter change may get your heater up and running again. Some heating systems are designed to shut down when a dirty filter clogs the airflow. If you have older equipment with a gas pilot, check the ignition to ensure the flame hasn’t blown out.

Repair or Replace?

Depending on the cause of a breakdown, a timely furnace repair can save you from the cost of a replacement. There are times, however, when upgrading to a high efficiency furnace is the best option. The Environmental Protection Agency offers a simple checklist that can help you determine if it’s more cost-effective to repair or replace your system.
