MYSON 402A3410 ASSEMBLY PRESSURE SWITCH E.A.

The Air Pressure Switch, also known as the APS is used as a safety device to ensure the fan is fully operational. The fan prevents a build-up of noxious fumes within the appliance, venting the fumes out of the property safely. The air pressure switch is tracked by the princted circuit board (PCB), ensuring that it is in service; if the air pressure switch is not working correctly the PCB will restrict the appliance from firing up .
