What to do if liquid line solenoid is not opening in Parker Controller?
If the liquid line solenoid is not opening, check the wiring from the controller to the valve, ensuring it is correct and that the proper voltage is feeding the valve. Also, verify that the fuse inside the controller is not blown. Refer to the Service section for the fuse replacement procedure.
How to fix Parker Controller if evaporator fans are not working?
If the evaporator fans are not working, check the wiring from the controller to the valve, ensuring it is correct and that the proper voltage is feeding the fans. Also, verify that the fuse inside the controller is not blown; see the Service section for the replacement procedure.
What to do if case lights are not working on Parker Controller?
If the case lights are not working, ensure the wiring from the controller to the valve is correct and that the proper voltage is feeding the lighting power supply/driver. Also, check the fuse inside of the controller to make sure it is not blown; see the Service section for the replacement procedure.
What to do if defrost heaters are not working on Parker Controller?
If the defrost heaters are not working, make sure the wiring from the controller to the valve is correct and that the proper voltage is feeding the heaters or hot gas solenoid. Also, check the fuse inside of the controller to ensure it is not blown; see the Service section for the replacement procedure.
What to do if Parker Controller is not powering up?
If the Case Controller is not powering up (and the power LED indicator is not lit), check the voltage at the Case Controller (Gnd and 24VDC). If the voltage is not 24VDC, replace the power supply. Also, make sure the wiring between the power supply and Case Controller is correct and retighten if necessary.
How to troubleshoot a Parker Controller display that is not powering up?
To troubleshoot a display that is not powering up, ensure the wiring at the Display Module (Gnd and 24VDC) is correct and retighten it.
Why is my Parker Controller display showing dashes?
If your Parker Controller display is showing dashes, the issue might be with the communications from the Case Controller (D+ and D-). Ensure the wiring is correct and retighten it.
What causes a Parker Controller display to be intermittent?
An intermittent display on your Parker Controller can be caused by the wiring between the Case Controller and the Display. Make sure the wiring is correct and retighten it.
