You got a defective inverter it seems like, look here:
I am a local appliance repair man I have recently gotten a kitchen aid 5 door model number KRFF707ESS01and I've been having some head scratchers with it I plug it in and it turns on and off and you hear a clicking.the first thing I did was replace the power supply control bored on the top. After...
Where did you buy it from?
Also look here:
We have a 2 year old KitchenAid KRMF706ESS01. Every few of days the fridge will stop cooling. After unplugging it, it will recover and seem to be humming along. Below are the symptoms after it fails: Cycles through this sequence: 1. Refrigerator valve clicks every second for a couple of...
Or the main control board is the cause:
Refrigerator Control Board WPW10675033
The board mounted to the compressor is blinking a green light twice with a pause in between. As you earlier post noted that is the absence of the 3-6 VDC from the control board.
My data sheet shows that as coming from the control board P8-7 and P8-8 and the schematic shows that as a red and a black wire going to the compressor inverter. Testing the pins on the main board with the cable not connected shows no VDC in the powered up not working state.
I then put the fridge in self diag number 4 waited till sub test 3 when the board would be commanding the compressor on. The pins still had no VDC
So please correct me if i am wrong the 3-6 VDC is the control side of a relay to put the compressor in and out of load as the control board detects the need for cooling.
You can check the voltage at the inverter:
Inverter--->black and white wires = 120 VAC,
red and black wires = 0-15 VDC
