Whirlpool ATR0742BPP0 Air Pressure Switch
The actual job of the air pressure switch is to see if the primary blower is on and running. An air pressure switch is part of a small, but important collection of mechanisms designed to keep everyone in the house safe. Most air pressure switches are constructed with a manual reset, which means it would need to be reset or the whole HVAC system will not continue operation.
Warning Signs of a Rapidly Declining Pressure Switch
- Incorrect volt running through the switch.
- The expected temperature in the house is rarely fully achieved.
- The blower fan will not function.
