Lennox G40UH-48C-110 Air Pressure Switch
The main function of the pressure switch is to determine whether or not the primary air circulator is doing what it is supposed to do. An air pressure switch is just one of the many indispensable aspects of the whole safety system that is intended to stop injuries or explosions. Some pressure switches may have a reset feature that is manual, which forces the system to be reset physically before you can continue using the system.
Signs that the System Pressure Switch is About to Fail
- Wrong electrical voltage being read.
- HVAC system does not actually get to the right temperature as set by the thermostat.
- The blower fan refuses to run.
