International Comfort Products H8MPL100F20B1 Air Pressure Switch
The primary function of the air pressure switch is to sense if the blower is actually running. A lot of switches are issued with a manual reset feature, which means it will have to be manually reset before the HVAC system will continue. This switch is one of the vitally important safety devices that are created to keep everyone in the house safe.
How to Know when the HVAC Air Pressure Switch is About to Fail
- Wrong voltage reading from the switch.
- The desired indoor temperature seldom attained.
