Frigidaire CPA12EDU111 Air Pressure Switch
The actual job of this type of switch is to see if the blower fan is running. A good number of pressure switches today are issued with a manual reset feature, which means it would need to be reset before the system will continue its normal operation. This pressure switch is one of many other devices designed to keep everyone in the house safe.
Important Signs that the Pressure Switch will go Bad
- Bad volt range being read from the pressure switch.
- The desired temperature in the house seldom attained.
- The blower fan refuses to run.
