International Comfort Products C9MPT075F14A2 Air Pressure Switch
The main job of the air pressure switch is to determine whether the blower fan is doing what it is supposed to do. This is one of the vitally important safety mechanisms designed to keep you safe. The majority of pressure switches are equipped with a manual reset feature, which makes you reset it by hand before the system will continue its normal operation.
Signs that your Pressure Switch will Soon Fail
- The set temperature is never fully achieved.
- Incorrect electrical voltage being used by the switch.
- Furnace is unable to ignite the gas.
