Potential Reasons Why Your Furnace Won’t Ignite
Regardless of how you set the thermostat, your furnace won’t turn on. You may feel quite worried if your furnace suddenly becomes unresponsive during cold weather. Don’t panic; there may be a relatively simple solution to this problem.
Power
First, look at the furnace’s emergency shutoff switch. A family member or visitor might have accidentally turned it off, especially if it’s located near a light switch. Your equipment should generally work as soon as you switch it on.
Check the building’s electrical panel. If the breaker for your heating system was tripped, try resetting it. Don’t reset it repeatedly or force it into position; this is dangerous, and the furnace probably needs repair before it can function safely.
Fuel
Confirm that your equipment still has fuel. If it runs on natural gas from a utility rather than a metal tank, service might have been disconnected. Otherwise, check the gauge on the tank. Be aware that some of these meters aren’t entirely accurate.
If you have a stove, dryer, or other equipment that burns the same fuel as your furnace, it can help you determine when you’ve run out of fuel. Test the appliance to see if it produces heat. When multiple pieces of equipment don’t turn on, you probably need a refill.
Pilot Light
Another possibility is that the furnace’s pilot light requires relighting. Any interruption in the fuel supply may cause it to go dark. However, you might not have to think about this problem; oil, electric, and some newer gas furnaces don’t use pilot lights.
Thermostat
When a furnace doesn’t turn on, a thermostat problem is often responsible. This device could need repair or merely require new batteries. If it has separate heating and cooling modes, verify that the correct mode is selected.
Access Panel
Did you recently open the furnace’s access panel? Your heating system might have a safety feature that shuts it off when the panel isn’t closed correctly. Check the owner’s manual for further details.
Upkeep and Maintenance
Some HVAC systems will eventually stop running if you forgo specific maintenance tasks. Failure can occur when the drain pan fills with condensation, or the air filter becomes clogged. A dirty filter may produce overheating, high energy bills, and or poor air quality.
If these basic troubleshooting steps don’t help, your equipment could need a new blower motor, thermostat, flame sensor, or other components. A knowledgeable HVAC technician can identify the cause of the problem and take steps to revive your furnace.
Let’s Sum Up The Reasons and Solutions Why Your Furnace Won’t Turn On
To sum it up, a central heating system might refuse to run when it lacks fuel, loses electrical power, needs maintenance, or has an unlit pilot light.
