Samsung UPC3240C Air Pressure Switch
The reason for the existence of this type of switch is to see if the primary air circulator is circulating the air as it should. This is one of many other mechanisms designed to stop injuries or explosions. The majority of pressure switches are programmed with a manual reset, by which you must manually reset it before the HVAC system will continue.
What to Look for when the Switch is About to Fail
- The proper temperature in the house is hardly ever fully achieved.
- The furnace can not run.
- Inaccurate volt being read.
