International Comfort Products HAC036AKA1 Air Pressure Switch
The actual job of the switch is to see if the primary blower is on and running. An air pressure switch is just one of many safety creations designed to stop injuries or explosions. Some different switches are issued with a manual reset feature, which makes you reset it by hand in order for the HVAC system to continue running.
Symptoms that the Switch is Starting to Go
- The furnace or AC will not run correctly.
- Wrong electrical voltage being read from the pressure switch.
- The expected temperature is hardly ever fully attained.
