Mitsubishi MUZ-GE18NA Air Pressure Switch
The function of the switch is to determine whether or not the air blower is doing what it is supposed to do. Some pressure switches may have a manual reset, which means you have to physically reset it or the whole HVAC system will not continue operation. This pressure switch is part of the safety system in place to keep you safe from injury or explosions.
Evidence of a Rapidly Declining Pressure Switch
- Bad volt being read.
- Your system doesn't get to the correct temp.
- The blower fan can not operate.
