Amcor AWS090HR Air Pressure Switch
The primary function of the air pressure switch is to see if the blower is running. A lot of switches may have a manual reset, which means you have to physically reset it before the system will continue its normal operation. This pressure switch is part of the safety system that is in place to keep you safe from injury or explosions.
Evidence of a Nearly Failed Pressure Switch
- The correct indoor temperature is rarely fully achieved.
- The furnace is unable to ignite the gas.
- Wrong electrical voltage reading from the switch.
