Lennox Furnace Not Turning On: Troubleshooting Guide
If your Lennox furnace has stopped working and you’re not sure why, you’ve come to the right place! A Lennox Furnace is designed to provide years of reliable, energy efficient heating and cooling, but sometimes they can run into issues that need to be addressed before they will turn on again. This guide will help you troubleshoot a Lennox furnace that won’t turn on, so that you can get your home heated up again and stop worrying about the cold.
Assess the Situation
The first step in diagnosing your Lennox furnace is to assess the situation. Here are a few things to consider:
- Is your furnace currently making any noise or emitting any type of smell?
- Are there any lights on the unit that are illuminated or blinking?
- Have you checked your home’s circuit and/or breaker box to make sure that the power is still on?
Once you’ve considered these questions, you should have a clearer idea of what might be causing your Lennox furnace to not turn on.
Common Issues
1. Poor Thermostat Settings
If your Lennox furnace isn’t responding, it may be because the thermostat settings are incorrect. Check the thermostat and make sure that it’s set to the correct temperature, and that the mode is set to “heat.”
2. Obstructed Air Filters
A clogged air filter can cause all sorts of issues with the function of your furnace. Make sure that the filter is free of dirt and debris, and if it is clogged, replace it with a new filter.
3. Broken Blower Motor
If your Lennox furnace won’t turn on, the blower motor may be to blame. Unfortunately, if the blower motor is malfunctioning, it needs to be replaced and should be done by a professional HVAC technician.
4. Faulty Igniter
The igniter can sometimes become faulty and needs to be checked for proper operation. A qualified technician should be able to diagnose and repair the issue.
The good news is that most of these common issues can be resolved without having to replace the entire furnace. With the help of a reliable technician, you can have your Lennox Furnace up and running again in no time.
Have a Professional Inspect Your Furnace

Solution Steps for Lennox Furnace Not Turning On in San Diego
H3. Preventative Action to Avoid Lennox Furnace Not Turning On Issues
Over time, even the best-maintained furnaces can wear out and may experience a variety of issues, including not turning on. To help prevent such issues, San Diego residents should take the following steps when it comes to caring for their Lennox furnaces:
H4. Scheduling Yearly Service Appointments
Much like cars require regular oil changes in order to continue functioning optimally, furnaces should receive yearly service appointments. During these appointments, a technician can identify any minor issues that could be addressed before they become major problems. This can help prevent a sudden breakdown and protect against any prolonged Lennox furnace not turning on issues.
H4. Changing the Furnace Filter
The furnace filter should be changed once every three months to keep the airflow unrestricted and the system running properly. This can help prevent dirt and other particles from clogging the system, which can lead to a Lennox furnace not turning on.
H4. Cleaning the Furnace
Homeowners should make sure to periodically inspect and clean their Lennox furnaces. Any dust or debris near the blower can restrict the flow of air or clog the system and lead to a Lennox furnace not turning on.
H4. Keeping the Air Vents Clear
Make sure to check the air vents often and keep them free of obstructions. Any buildup of dirt, dust, or debris could restrict the airflow and lead to the Lennox furnace not turning on.
H4. Closing Windows and Doors
If the Lennox furnace doesn't seem to be turning on, San Diego residents should make sure their windows and doors are closed and the thermostat is set to ‘heat’. Closing the windows and doors can help prevent conditioned air from escaping and can keep the thermostat registering correctly.
By following these preventative steps, San Diego residents can help ensure that their Lennox furnaces remain in top condition and reduce their chances of experiencing a Lennox furnace not turning on issue. If a problem does occur, or if the furnace fails to turn on, it's best to contact a local appliance or HVAC technician for assistance.
