Lennox XP16-060 Air Pressure Switch
The reason for the existence of the switch is to sense whether the blower fan is on and running. This switch is one of many other aspects of the whole safety system that is intended to keep everyone in the house safe. The vast majority of pressure switches made today have a manual reset feature, which makes you reset it by hand before the entire HVAC system will continue operating again.
Clues that your System Pressure Switch is Starting to Go
- The blower fan can not function.
- Wrong voltage reading.
- The desired temperature indoors seldom fully achieved.
