How can I check the ribbon cable connection on my Kodlfront WAC or WTC Series air conditioner?

While rare, excessive vibration during shipment may cause the ribbon cable that connects the front control panel to the control board to become disconnected. This can result in a unit that will not power on and/or may appear to power on but will not perform all functions correctly. To remedy this issue, the ribbon cable connection must be checked and re-connected if loose or disconnected.

Please refer to the below instructions:
