Furnace Not Turning On? Get Professional Troubleshooting

If you've noticed your furnace is no longer running, you're probably wondering what's going on and how to fix it. Many homeowners don't have the know-how to accurately troubleshoot their furnace, and it's best to leave it to the professionals. From electrical or mechanical issues to a simple clogged filter, here is what you need to know about furnace troubleshooting.

Common Reasons Your Furnace May Not Turn On

The most common causes of furnace malfunction include clogged filters, tripped breakers, blocked exhaust vents, faulty thermostats, and electrical malfunctions. To identify the issue, it's important to first assess the system.

When it comes to clogged filters, it’s important to remember that clean filters ensure the circulation of air in the home. Poorly maintained filters create a buildup of grime, dirt, and other particles which can restrict airflow and force the furnace to shut down. A simple change of the filter can usually fix this issue.

If the filter looks fine and the thermostat is working properly, there could be a problem with the wiring or another type of malfunction. In this case, it's best to call a professional furnace repair technician who will assess the problem and determine the best way to repair or replace any faulty components.

Invest in Preventative Maintenance

Many homeowners don't spend the time to properly maintain their furnace, however, this is a crucial step to make sure everything is functioning correctly and to prevent costly repairs down the road. A professional technician will be able to inspect the system, identify small problems before they become large, and make sure all parts are in working order. This also includes cleaning the blower, replacing worn belts, and checking for gas leaks.

The energy efficiency of a furnace also depends on a clean burner and heat exchanger. If these parts aren't properly maintained and chemically cleaned, the furnace won't run as efficiently as it should and can even be hazardous.

If you have noticed your furnace not turning on, it’s best to call a professional immediately. A reliable and experienced furnace repair technician has the knowledge and expertise to assess the problem and find the best solution. They will discuss options for further preventative maintenance that may be beneficial to your system. Plus, regular maintenance can reduce your energy bills, save money in the long run, and help you avoid costly troubleshooting.

Furnace Not Turning On

PLEASE Prior to engaging a local appliance or HVAC technician to diagnose and repair any issue with your furnace, there are a few preventive actions to consider.

1. Check The Electrical Power Source

To ensure that the furnace is receiving power, check the main power switch as well as the fuse box or circuit breaker. The power switch is typically near the furnace and is either a switch or lever that looks like a light switch. If there is no current running to the furnace, ensure the switch is in the on position.

2. Check the Thermostat

Verify the thermostat is set to heat, the temperature is set to a desired level and the system is switched to auto. If the switch is set to off, the furnace will not turn on. If the other settings are correct, check the batteries (if applicable).

3. Check or Replace Any Filters

Filters located either in the return air duct or on the blower cabinet should be inspected and/or replaced at least every three months as dirt and dust buildup may cause restricted airflow, leading to the furnace not turning on.

4. Test The Pilot Light

If the furnace is gas-powered and has a pilot light, try to relight the pilot light. If the pilot light is burning, your furnace should operate as normal.

5. Test The Fan Motor

In electric furnaces, the fan motor is usually the first component to fail. If you can hear the fan running but the furnace is not producing heat, the fan motor may need to be replaced.

6. Check The Blower Start Capacitor

Check the manufacturer’s operational specs as capacitors of different sizes are required for different motors. If the capacitor is damaged, it must be replaced.

PLEASE Following manufacturer recommendations or local technician best practices will help identify and address furnace not turning on issues before they arise.
