International Comfort Products PAF042K000A Air Pressure Switch
The primary function of the switch is to see if the air blower is running properly. A good number of pressure switches today are constructed with a manual reset, which means it will have to be manually reset or the entire system will not run. This switch is just one of many aspects of the whole safety system that is intended to stop injuries or explosions.
Signs to Look for when your Air Pressure Switch is Beginning to Fail
- The furnace or AC can not function properly.
- Inaccurate voltage range being read.
- Your system doesn't achieve the desired temperature as set by the thermostat.
