Nordyne M1BC066 Air Pressure Switch
The main function of the air pressure switch is to sense whether the blower fan is actually running. This is just one of the many indispensable mechanisms designed to keep everyone in the house safe. Some pressure switches are equipped with a manual reset feature, by which you must manually reset it or the entire system will not run.
What to Look for when your Pressure Switch is Starting to Go Bad
- Your furnace will not run.
- The desired temp seldom achieved.
- Incorrect volt reading from the switch.
