LG LMU360CE Air Pressure Switch
The main job of the air pressure switch is to sense whether the main blower is circulating the air as it should. This switch is one of the critical safety creations designed to keep you safe. A good number of pressure switches today have a manual reset feature, which makes you reset it by hand or the whole HVAC system will not continue operation.
How do you Know when the Switch is Starting to Go Bad
- The furnace can not run.
- Inaccurate volt being used by the switch.
- The set temperature in the house seldom achieved.
