LG LMAN120CNS Air Pressure Switch
The primary function of an air pressure type switch is to sense if the primary blower is circulating the air as it should. A lot of switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation. An air pressure switch is one of the critical device to stop injuries or explosions.
How do you Know when your Pressure Switch is About to go Bad
- The expected temperature in the house is hardly ever fully achieved.
- Incorrect volt reading from the switch.
- The blower fan refuses to operate.
