I have a KitchenAid side by side that will not defrost. I've tested the defrost thermostat (W10225581) and it reads closed when cold and open when warm. Also tested the heater element and it was under 100 ohms. I believe it to be the control board (W10366604). Something else to note is the water filter indicator light flashes green and will not reset. When the defrost thermostat is closed it flashes faster that when it is open. Is this an error code or some kind or just the control board shorting out?
ANSWER Hello John,
The Adaptive defrost control board W10366604 will need to be replaced due to the defrost issue. The water filter light flashing is also an indicator that the board has failed. Once new board is in then the light will work as normal.
