Mitsubishi PKA-A12HA Air Pressure Switch
The actual job of this type of switch is to sense whether the main blower is doing what it is supposed to do. This switch is one of many other devices designed to keep your family safe and sound. The vast majority of pressure switches made today may have a manual reset, which means it will have to be manually reset before the system will continue its normal operation.
Precursors that the Switch is Going Bad
- The desired temperature in the house is rarely fully achieved.
- Furnace refuses operate at all.
- Incorrect electrical voltage being read from the pressure switch.
