To tell if the gas valve to your furnace is bad, you can do the following:
Turn off your furnace’s gas supply, turn the thermostat up and check to see if there is no flame.
Check the pilot light to see if there is gas flowing to it, set the thermostat to below room temperature and wait a minute to see if there is a flame.
Set the gas knob to “ON” if the burner doesn’t turn on, set the thermostat above room temperature and perform a voltage test.
If you do not have the correct furnace knowledge or tools, you may want to have an HVAC technician perform these tests for you to determine if the gas valve on your furnace is bad and needs to be replaced. To get your furnace repaired, call us today.
