Lennox G61MPV-36C-090 Air Pressure Switch
The job of the switch is to sense whether the primary air circulator is circulating the air as it should. Some pressure switches may have a reset feature that is manual, which means you have to physically reset it in order for the HVAC system to continue running. This pressure switch is one of many other devices that are created to stop injuries or explosions.
Signs that the Air Pressure Switch is About to go Bad
- Inaccurate voltage range being read from the pressure switch.
- The furnace or AC refuses to operate.
- The desired temp is almost never fully attained.
