Lennox OF25-120 Air Pressure Switch
The actual job of this type of switch is to determine whether the main blower is running. A good number of pressure switches today are constructed with a manual reset, which means you have to physically reset it in order for the HVAC system to continue running. This is part of a small, but important collection of mechanisms designed to stop injuries or explosions.
Signs that your System Pressure Switch is Starting to Fail
- The correct indoor temperature is almost never achieved.
- Furnace can not operate.
- Incorrect voltage running through the switch.
