Nordyne Q6SD Air Pressure Switch
The main job of the air pressure switch is to determine whether the air blower is actually running. Some pressure switches are designed with a reset that is manual instead of automatic, which makes you reset it by hand before the HVAC system will continue. This is just one of the many indispensable devices designed to keep everyone in the house safe.
Symptoms that your HVAC Air Pressure Switch is Beginning to Go
- Bad volt running through the switch.
- Your furnace refuses ignite.
- Your system doesn't get to the correct temperature as set by the thermostat.
