To display diagnostics depress the ON key three times. The digital display will then display any active fault codes.
Pressing the ON again will scroll through any existing error codes.

Additional Troubleshooting:
No Display
• Turn on Control Panel with the ON key.
• Check to see if the display illuminates.
• Verify that the Control Panel is plugged into the wire harness.
• Check to see if wire harness is wired into vehicle properly.
Problem: Control Panel Not Working or Nothing Works
Control Panel
1. If the control panel shows a display when turned on, the control panel is getting power. 2. Disconnect one of the
sensors (Cab temperature or evaporator probe) or unplug the water valve. Press the ON key three times to enter
the error checking mode. The appropriate error code should be displayed. If error code is displayed, control to
ECU is making connection. If not, check wire harness connections, power to the ECU module, or replace the
control panel.
3. If only certain functions do not seem to work on the control panel, inspect the keypad tail for being pinched. If
connector tail is pinched and/or keys do not work, replace control panel key pad. SEE PHOTOS (Arrow pointing
to connector tail)
Problem: Setpoint Temperature Not Maintained Properly
Cab Temperature Sensor (4-pin white connector)
1. Verify that the fan is spinning. Check for dust or debris and clean with “dust off” if necessary. Clean connector
plug.
2. Voltage between Red and Black wires should be close to the vehicle voltage (12V or 24V).
3. Voltage between the two yellow wires should be between 0 and 5 volts (5V when the sensor is not connected).
4. Resistance across gray wires (Sensor unplugged). SEE CHART
