Questions & Answers

For Whirlpool Ice Machine Electronic Control Board (Part Number: OEM18047088)

1 Answer

Dale, it is possible that the water level sensor WPW10548509 has shorted and causing this problem. To verify if this is the problem, with the unit unplugged, disconnect the water level sensor from the wire connector and turn the unit on. If the ice machine starts to operate, this indicates the sensor has failed and would need to be replaced. If the unit does not start to operate after doing this, then the main control WPW10141364 would be the most likely cause.

Henry for Model Number KUIS15NRTB0

Hello. Ice machine is not working normally. the ice maker turns on, picks up water (the water sensor works, I checked), and turns on the compressor. runs for 20 seconds and turns off the compressor. water continues to be supplied to the evaporator. Temperature sensors I checked they are good. I replaced the main board working in the same way as with my board. I turned off the control buttons - it did not help. I turned on the compressor forcibly - the compressor works well. help please solve this problem. Henry for Model Number KUIS15NRTB0 ANSWER Hello Henry, check the water reservoir is filling completely, if not then you will need the water valve WPW10217917 if it is fully filling then disconnect the low water level sensor, it is next to the recirculation pump and has a 3 wire connector, run a cycle to check operation ,if needed the sensor is part WPW10548509. Thanks for the answer.   The water is completely filled, the sensor is in good condition, I measured the voltage at the output of the sensor, depending on the filling of the tank -good

Henry,

With the compressor only coming on for 20 seconds then shutting off then this would most likely be caused by a faulty start device for the compressor.

Terry for Model Number KUIA18NNJS11

I have a KUIA18NNJS11 under counter icemaker that was working fine and now the circulation pump AND the drain pump stopped working at the same time. I have entered diagnostic mode and when I get to the step for the circulation pump to kick on it does not. Also, in the next step the drain pump does not come on. All other steps check out fine I have checked voltage on each plug for the pumps and they each show around 12-13 volts when they are supposed to be energized during the diagnostic mode. I have a 2nd kitchenaid ice maker and I tried switching the pumps with the same results so it is not the pumps that are the issue. I also switched control boards and the control board worked when I installed it into my other working icemaker so the control board does not appear to be the issue either. What I am confused about is how there is voltage to the pumps but they do not come on. As I said, I know the pumps work because I installed them into another machine and they work fine. Is there something I am missing? Is there a common wire that feeds both pumps? Not sure where to check the harness besides in the control housing and it looks fine. Any help is greatly appreciated! Thank you, Terry

Terry,

The common wire between the 2 pumps would be the red black wire, look for corrosion on the connectors or for an issue with the connection points since there is voltage but not coming on. Check for breaks in the wiring.

Ron,

Double check to make sure that the hoses are connected properly to the circulation pump. If this checks ok then test to see if there is voltage to the pump. If there is not power then this will be a faulty main control board.

Mike,

You will want to check the transformer on the unit to ensure that it is good and if it checks ok then this will most likely be a faulty control board.

Tommy,

If there is water running across the grid but not forming ice then this will most likely be a issue with the compressor not turning on and will want to check for the overload and relay to be faulty.

Chris for Model Number GI15NDXXB1

My machine's water reservoir isn't filling up with enough water to circulate. I've recently replaced the pump at the bottom of the reservoir and a sensor (AP6022829) due to pump making a lot of noise and the black wire leading out of it sensor breaking. The circulating pump was replaced about a year ago. The machine is about 5 years old. 1) What tests/diagnostics can I perform on the machine (server mode) to see what could be the problem? 2) I am concerned the amount of time I've disassembled and reassembled the interior as irreparably broke the machine. At what point should I consider replacement?

1 Answer

Hello Chris. If the pump and sensor is new, then the next step is replacing the valve W10585391. It may not be opening enough to let the correct amount of water into the unit. The last part is the board. Thank you.

JetSkier,

You will want to check the water valve to make sure that there is 120 vac getting to it. If there is then the water valve would be bad and if not then the issue will most likely be a faulty control board.
