Lennox G43UF Air Pressure Switch
The actual job of the air pressure switch is to determine whether the main blower is running properly. This pressure switch is one of the vitally important safety facets of the HVAC safety checks that are dedicated to stop injuries or explosions. The vast majority of pressure switches made today are programmed with a manual reset, which makes you reset it by hand in order for the HVAC system to continue running.
Signals that the System Pressure Switch is in Need of Replacement
- The desired temperature is hardly ever fully attained.
- Inaccurate volt range being used by the switch.
- Your furnace won't ignite.
