International Comfort Products PGC036K060A Air Pressure Switch
The actual job of the switch is to figure out if the main blower is actually running. Some particular air pressure switches can have a manual reset, which makes you reset it by hand or the whole HVAC system will not continue operation. This switch is part of the safety system in place to keep you safe from any injuries.
What to Look for when your Pressure Switch is About to Fail
- The furnace or AC can not operate.
- The expected indoor temperature is almost never reached.
- Wrong electrical voltage being used by the switch.
