International Comfort Products PGMD60G1504 Air Pressure Switch
The function of the pressure switch is to sense whether the main blower is doing what it is supposed to do. The vast majority of pressure switches made today are constructed with a manual reset, which makes you reset it by hand before the HVAC system will continue. The air pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from harm.
Symptoms that the HVAC Air Pressure Switch will Soon Fail
- Inaccurate voltage range being used by the switch.
- System does not achieve the desired temp.
- Furnace won't run.
