Carrier EK Air Pressure Switch
The actual job of the switch is to determine whether or not the main blower is running properly. This switch is just one of many aspects of the whole safety system that is intended to keep you safe. Some different switches are equipped with a manual reset feature, which means you have to physically reset it in order for the HVAC system to continue running.
Clues that your Air Pressure Switch is Needing to be Replaced
- The expected temp is almost never attained.
- Furnace can't ignite the gas.
- Incorrect volt range reading from the switch.
