4. At this point, you will need to unplug the following wires on the control board (starting in the upper left corner and moving clockwise).

• Compressor (Red with Blue Cover) • Power (Black) • Fan (Blue Wires & White Connector) • Compressor (White) • HGB (Black Wires) • Pump (Black & White Wires) • Display (White) • RH Sensor (Blue with Red)




• Coil Temp. Sensor (Red with Blue) • Coil Temp. Sensor (Red/Blue with White) • Pump (Red With Blue) • Pump (Red/Black with White) • Power Cord (Black Wire)

5. Once the wires are unplugged, you can lift the the control board out of the machine. To do this, you will need to use the needle nose pliers. Use the pliers to push in the 4 “arrowhead” tabs (one in each corner). Simply squeeze each tab with the pliers so the control board can be lifted over the tab.

6. Now you’re ready to set the old control board aside and insert the new one. Carefully set the replacement control board in place, ensuring the tabs secure into place.




7. Next, reinsert the wires into the control board. It’s helpful to go in the reverse order removal: (starting at the bottom left corner and moving counterclockwise).

8. Once the wires are plugged in, screw in the control board cover, and close the machine.
