Lennox G40DF-48C-090X Air Pressure Switch
The primary function of an air pressure type switch is to determine whether the primary air circulator is running properly. This is one of the critical safety creations designed to keep your family safe and sound. The vast majority of pressure switches made today are designed with a reset that is manual instead of automatic, which means you have to physically reset it or else the system will cease to function.
Signs to Look Out for when the HVAC Air Pressure Switch is Starting to Fail
- Bad electrical voltage running through the pressure switch.
- The right indoor temperature is almost never attained.
- Furnace will not ignite the gas.
