Identifying Problems with Your Furnace’s Electronic Ignition

There aren’t many things worse than turning on your furnace and discovering that it doesn’t work. If you hear clicking noises but nothing happens, the electronic ignition was unable to ignite. Before you schedule furnace repair in Greensboro, NC, troubleshoot the problem using the steps below.

Thermostat Malfunction

Check the thermostat display. Some electronic thermostats show an error code if there’s a problem. The display might also tell you what the problem is.

Gas Line Issues

Make sure the gas is turned on by checking the shut-off valve outside. Check the gas supply line to ensure that it’s clear. If you smell gas, leave the house, and call for help immediately.

Clogged Air Filter

A dirty furnace filter or clogged vents and registers can greatly reduce airflow. That can cause the furnace to stop working. If airflow obstruction is severe, the heat exchanger can overheat and shut off before it heats your home.

Faulty Ignition Sensor

A malfunctioning ignition sensor or pilot light is a common reason why furnaces won’t ignite. The pilot or sensor may be dirty or broken. Replacing it is an easy fix for a professional technician.

Furnace Is Tripping the Breaker

Ensure that the furnace power switch is turned on. Check to see if the breaker has been tripped. If it has and continues to trip, call for expert furnace services at once.

Pilot Light Needs Time to Warm Up

Is it the first time this year that you’ve tried to ignite the pilot? If so, it may take longer to power up. The length of the gas line will determine how long it takes for the furnace to start delivering heat.

Most furnace problems can be solved proactively with fall tune-ups. Call Total Heating & Cooling, Inc., to schedule heating maintenance and other expert furnace services.
