International Comfort Products PGMD36G0606 Air Pressure Switch
The main job of the pressure switch is to see if the blower is circulating the air as it should. This is one of the key safety creations designed to keep you safe. A lot of switches are designed with a reset that is manual instead of automatic, which means it would need to be reset or else the system will cease to function.
Signals that the HVAC Air Pressure Switch is Starting to Go Bad
- Wrong electrical voltage being read.
- Your furnace won't ignite the gas.
