Lennox OF25-105 Air Pressure Switch
The main function of the air pressure switch is to determine whether or not the primary air circulator is actually running. This switch is part of the safety system in place to keep you safe from potential hazards in the house. A good number of pressure switches today have a manual reset feature, which forces the system to be reset physically before the entire HVAC system will continue operating again.
Symptoms that your Switch is Beginning to Fail
- Incorrect voltage being used by the switch.
- Your system doesn't reach desired indoor temp.
- The furnace will not operate.
