International Comfort Products HAC242AKA1 Air Pressure Switch
The primary function of the switch is to sense if the air blower is circulating the air as it should. This is just one of many mechanisms designed to stop injuries or explosions. Some different switches may have a manual reset, which means it would need to be reset or the whole HVAC system will not continue operation.
Symptoms that the Switch is in Need of Replacement
- Your furnace won't ignite.
- Incorrect electrical voltage reading.
- The correct indoor temperature is almost never reached.
