Nordyne M1M Air Pressure Switch
The main job of the pressure switch is to see if the primary blower is doing what it is supposed to do. Some particular air pressure switches are equipped with a manual reset feature, which means you have to physically reset it before the HVAC system will continue. The air pressure switch is a very critical piece of the safety system that is in place to keep you safe from potential hazards in the house.
How to Know when your Air Pressure Switch is Beginning to Fail
- Bad voltage being used by the switch.
- The blower fan is unable to function properly.
- The proper indoor temperature is never fully achieved.
