Troubleshooting Problem Cause Solution Power Source Using a Phillips Head screwdriver, remove the eight screws holding the pressure control assembly. Locate the red light on the board indicating there is power. If the light is ON, see Pressure Control Assembly (Board). If the light is OFF, locate the L1 and L2 termi- nals on the board.
Troubleshooting Problem Cause Solution Sensor Plug another sensor board into the board and perform the zero calibration procedure. If the machine starts to run, the sensor is bad. If there is no replacement sensor available, use a multi-meter to test the resistance across the red and black wires of the sensor (be sure to test the plug).
