Carrier 38QRR024 Air Pressure Switch
The reason for the existence of the pressure switch is to see if the blower fan is blowing air. This switch is one of the critical facets of the HVAC safety checks that are dedicated to keep everyone in the house safe. Some pressure switches are issued with a manual reset feature, from which it would have to be reset manually before the system will continue its normal operation.
How do you Know when your Pressure Switch is in Need of Replacement
- Incorrect electrical voltage reading from the switch.
- The furnace won't ignite the gas.
- Your system doesn't actually get to the right temperature.
