International Comfort Products C9MPT100J16B1 Air Pressure Switch
The actual job of the switch is to figure out if the main blower is blowing air. This switch is part of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions. Various air pressure switches are constructed with a manual reset, which means it would need to be reset in order for the HVAC system to continue running.
Signs that the HVAC Air Pressure Switch is About to Fail
- System does not reach desired temperature.
- Inaccurate electrical voltage being read from the pressure switch.
- The furnace won't ignite the gas.
