Lennox OF25-120R Air Pressure Switch
The reason for the existence of the switch is to determine whether the primary air circulator is doing what it is supposed to do. Some particular air pressure switches are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset before the entire HVAC system will continue operating again. This is one of the critical mechanisms designed to keep everyone in the house safe.
Signs that your Switch is About to Fail
- Wrong volt reading.
- The expected temperature in the house seldom attained.
- The blower will not run correctly.
