Brand: KitchenAid
Model Number: KRFC704FPS03
Main Symptom: ice maker not working and water dispenser working intermittently
What happens & when: no ice being made and water dispenser will turn off mid-stream. You have to open the door once or twice before the water dispenser will work again. Should I replace the control board? How can I test whether the control board is working properly?
Error Code (if any): n/a
Parts or tests already tried: replaced water inlet valve

Voltage tests at the valve can be done to identify if the main control sends 120 Volts AC to the valve when water is being called for. Another indicator of the valves getting voltage is if they hum. However, if there is a wire harness break at the top left door hinge, it can create both of these issues. If you remove the hinge cover, do any wires look like they may be pinched or damaged? If the wires look good, this process can be used to run an ice maker test. Press both temperature down buttons at the same time and hold them. The temperature display should count down, followed by a chime indicating the service mode has been entered successfully. From there, press the upper temperature up button until the display shows 120 then press the drawer button. This will activate an automatic ice maker diagnostic cycle. The display will change as the ice maker status changes ass seen in the attached image. Once the ice maker goes through the diagnostic cycle, press the max cool button to exit the test, then press and hold both temperature down buttons for 3 seconds to exit the diagnostic mode. Let me know what you find and we can go from there.
Hi William - thank you for the detailed response. I checked the wiring in the door joint and didn’t notice any unusual wire issues. I tried the ice maker diagnostic test three times but it timed out each time and never gave me any error codes. I also didn’t hear any noise (if I was supposed to) as the ice maker was cycling during the test. Let me know if you have any other thoughts on the issue here. Thanks again!
The next step would be to use the diagnostic test mode to go to test 97. Once 97 is shown on the display, and the Drawer button is pressed, do you hear a valve hum for about 7 seconds? If not, it may be necessary to repeat this step while using a multimeter to test for 120 Volts AC at the ice maker fill valve. More than likely, there will not be voltage found as I suspect the main control is likely causing the failures. Especially if the water dispenser is shutting off mid stream and there is not a hum from the valves. If the main control does end up being the cause of failure, it is a part of a kit.
