Lennox HPXB15-036 Air Pressure Switch
The main function of an air pressure type switch is to sense whether the main blower is on and running. This is just one of the many indispensable mechanisms designed to keep you safe. The vast majority of pressure switches made today are equipped with 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 About to go Bad
- The correct indoor temperature seldom achieved.
- Your heating and cooling system can not function properly.
- Bad voltage reading.
