What does it mean when your furnace makes a clicking noise?
Clicking furnaces are more than a nuisance. Gas furnaces, especially, should be checked out by an HVAC professional for any clicking sound or other strange noise. Clicking from gas furnaces often indicates a problem with the gas valve or ignitor—and you certainly don’t want a gas leak.
What does it mean when thermostat keeps clicking?
It is normal for the thermostat to make clicking noises. The clicking noises are the relay opening and closing to let the power through to the heating system.

What does a clicking thermostat mean?
The click you hear from your thermostat is probably the electrical relay triggering the power to the furnace, air conditioner or heat pump. It is a normal sound.

Why does the thermostat click but there is no air?
The thermostat clicks but nothing happens. This might be because your thermostat is actually on the wrong setting. In order for the furnace to start running, you need to set the thermostat for a temperature that requires the air to be warmed up. You can try to turn up the set temperature significantly, just to test the system.
Why does my AC keep clicking on and off?
If you hear one loud click as the AC tries to turn on, there’s a problem with the controls. The culprit could be the capacitor, control board or thermostat. If the clicking happens repeatedly until you manually turn off the AC at the thermostat, the controls might be fine but some other part is refusing to do its job.
Do you need to set the thermostat for the furnace?
In order for the furnace to start running, you need to set the thermostat for a temperature that requires the air to be warmed up. You can try to turn up the set temperature significantly, just to test the system. The other settings on your thermostat matter too. Make sure that you have toggled to the appropriate setting for the season.
What should I do if my thermostat is not sending a signal?
The thermostat should emit a clicking sound and the furnace should also make a sound. If the furnace does not make a sound, the thermostat is not sending a signal and needs to be replaced. Turn off the breaker to your furnace. Remove the cover from the thermostat to expose the wiring.
