Furnace Not Turning On

A damaged furnace is one of the most common problems that homeowners face throughout the winter. Furnace failure can be triggered by a couple of different reasons. Some of these problems can be resolved easily with testing, while others need professional assistance. Here are the most common causes why your furnace won’t turn on, as well as what you can do about it. Furnace Not Turning On

Furnace Power Switch

The furnace switch is the source of energy and is commonly found next to or on the side of the furnace. It looks a lot like a power bulb. Ensure that the switch is in the “On” mode and also that your furnace turns on. If the switch is set to the “Off “mode it will not turn on

Check Your Circuit Breaker

The furnace would not turn on if there is no power. It is important to reset the circuit breaker that controls your furnace if it breaks. Check your breaker box to see whether your HVAC circuit breaker has tripped or not. If your circuit breaker has tripped, turn the tab to restore power to your furnace.

Check If The Gas Valve Is Turned Off (For Gas Furnace)

Check to see if the gas valve on the furnace’s gas line is turned on. If it’s turned on, the lever will be parallel to the gas line. However, if it is perpendicular, this means that the gas is turned off. If the gas is turned off, turn the gas valve handle parallel to the gas line to see if the furnace starts to work.

Thermostat Issues

Don’t forget that your thermostat is an important component for maintaining a constant temperature in your home. Everything can get cold if something goes wrong with this device! You’ll also need batteries for replacement if the old ones run out. So make sure to check the thermostat and its batteries once in a while.

Broken or Loose Thermostat Wiring

Your thermostat is unable to connect with your furnace if any of the thermostat wires are loose or broken. As a result, if the link inside your thermostat is interrupted, your furnace is likely to stop working. You can remove your thermostat and check the wires to ensure they are safe and free of visible damage.

Check Thermostat Settings

When your HVAC system fails, we recommend that you check the settings of your thermostat. First, double-check that it’s set to heat. If your thermostat is set to ‘Cool,’ your heating system would not work.  It’s also possible that the thermostat is set to ‘fan only’. Check and make sure that the fan is set to ‘Auto’.

The heating system will not turn on if it cannot identify that the room has reached the desired temperature. Check to make sure your thermostat isn’t set too low. You might also want to invest in a programmable thermostat to gain more control over your home’s temperature.

Check Your Air Filter

If the air filter is blocked, airflow will be blocked, and your HVAC system will be unable to perform efficiently. Your furnace may struggle to keep up with household needs if there isn’t enough ventilation, and it will overheat. It’s easy to ignore your air filters; however, if they’re blocked with dust and dirt, your HVAC system won’t be able to function properly. Therefore, make sure that you check and replace dirty air filters routinely.
