DIAGRAM).

F. Inoperative control board. No output from board to solenoids.

Remedy

E.Check that expansion valve is operating by touch (should be able to feel valve pulse).Check for loose or disconnected wire to solenoid coil. If necessary, troubleshoot expansion valve with a gage set to see if it is opening. If expansion valve is not opening, suction pressure will be in a vacuum.

F.Check LED’s on control board to see if they are modulating. Check for 24V output to pulse modulating expansion valve (see WIRING DIAGRAM). If control board green LED is on and yellow LED Is flashing; but no 24V output, replace board.

NOTE: If overload protector cuts out compressor, condenser fan motor will continue to operate otherwise; troubleshooting condenser fan motor problem is same as for ‘‘COMPRESSOR DOES NOT OPERATE’’paragraph plus the following:
