Friedrich MR09C1H Air Pressure Switch
The job of an air pressure type switch is to determine whether or not the primary air circulator is on and running. A lot of switches may have a reset feature that is manual, from which the switch will have to be manually reset before you can continue using the system. An air pressure switch is one of many other mechanisms designed to stop injuries or explosions.
What to Look Out for when the HVAC Air Pressure Switch is Starting to Go Bad
- Wrong volt range reading from the switch.
- The blower fan is unable to run.
- The set temperature is never fully achieved.
