International Comfort Products H8MPT050B12A1 Air Pressure Switch
The primary function of this type of switch is to determine whether or not the air blower is doing what it is supposed to do. Various air pressure switches are constructed with a manual reset, which means you have to physically reset it before the HVAC system will continue. This pressure switch is one of the critical aspects of the whole safety system that is intended to keep you from harm.
Warning Signs that the Switch is Beginning to Fail
- The blower fan will not function.
- The desired temp is hardly ever fully attained.
- Wrong voltage being used by the switch.
