GREE 30138517 Control Board 320720-756 For maritime models with Monel

For maritime models with Monel trim or ammonia-specific valves

allowing for accurate sensing of pressure variations across fans

it should be mounted in the upright and level position

Replacing a fouled or cracked flame rod sensor with this unit is a standard solution for resolving persistent short cycling or furnace ignition failure in the field

Avoid over-tightening the electrode support set screws
