  If your KitchenAid Ice Maker won't run, several factors could be at play. First, check your circuit breaker and fuses to ensure there's power at the wall outlet. Also, inspect the auxiliary drain pump power outlet for any issues like a kinked drain hose, blocked screen, or obstructed vent. A disconnected selector switch or loose connections at the switch or control board can also be culprits; reconnect or repair these as needed. Verify the power cord's continuity and replace it if it's open. Lastly, if the room temperature is below 55°F (13°C), the bin thermistor might be shutting the unit off, or ice might be touching the thermistor, which is normal operation.

Why is my KitchenAid Ice Maker's ice production so poor?

  If your KitchenAid Ice Maker is producing ice poorly, it could be due to several reasons. If the room temperature is below 55°F (13°C), the bin thermistor might be shutting off the unit. A seeping water valve with a hot condenser can also cause this issue, requiring the water valve to be replaced. Additionally, a slow or defective drain or drain pump that causes water to back up into the bin can be the problem; in this case, you should repair or replace the drain or drain pump.

What to do if my KitchenAid KUIA15NRH*11 Ice Maker won't make ice, the reservoir is full, and the evaporator is warm?

  ballardreginaldAug 20, 2025
  If your KitchenAid Ice Maker will not make ice, and the water reservoir is full, but the evaporator is warm, there are a few potential causes. First, test the compressor, relay, and overload, as the compressor might not be running. Another possibility is a blocked condenser or a stalled fan motor, which would require cleaning the condenser or repairing/replacing the motor. Finally, the unit might simply be in startup mode; wait 5 minutes and check again.

Why is there too much ice in the bin of my KitchenAid KUIA15NRH*11 Ice Maker?
- R
  Robert NewmanAug 25, 2025
  If there's too much ice in the bin of your KitchenAid Ice Maker, it's likely due to a defective bin thermistor, which will need to be replaced.

What to do if my KitchenAid KUIA15NRH*11 Ice Maker won't make ice, the water reservoir is empty, and the evaporator is cold?

  If your KitchenAid Ice Maker won't make ice, and the water reservoir is empty while the evaporator is cold with a thin or no ice slab, several issues could be the cause. Make sure the water supply is turned on. Check for a loose or missing reservoir cap and tighten or replace it if necessary. Ensure the water slide return tube and inlet tube are correctly positioned within the reservoir; reposition them if they are out of place. If the water inlet tube is frozen near the evaporator, thaw and reposition it. A defective inlet water valve may also be the problem, requiring testing, repair, or replacement. Lastly, if an ice slab only partially released and water bridged down into the bin, look for interference with the cutter grid and clean the evaporator plate.

Why is my KitchenAid KUIA15NRH*11 so noisy?
- J
  Jose SchwartzSep 3, 2025
  If your KitchenAid Ice Maker is noisy, the cause could vary. A banging sound is usually normal, as it's the slab dropping off the plate and ice dropping from the cutter grid into an empty bin. A grinding, cavitating sound might indicate that the reservoir is empty. Check for a partially released slab or interference with the cutter grid, and clean the evaporator plate. If the reservoir is full and the grinding, cavitating sound comes from the recirculation pump, replace the pump. A noisy drain pump may need repair or replacement.

What does it mean if the service LED is on for my KitchenAid Ice Maker?
- J
  Jordan HoustonSep 6, 2025
  If the service LED is on (or the Off LED on some models) on your KitchenAid Ice Maker, it could be due to an open or disconnected bin thermistor or thermistor wiring, which requires testing the thermistor and wiring harness or reconnecting them. Another possible cause is a defective, loose, or mispositioned evaporator thermistor, which also requires testing the thermistor and wiring harness or reconnecting them.

  Tyler CarterSep 10, 2025
  If your KitchenAid Ice Maker is producing cloudy, soft, thin, or poor-tasting ice, it could be due to poor water quality.

What to do if my KitchenAid Ice Maker won't make ice, the water reservoir is full, and the evaporator is cold with a thin/partial/irregular ice slab?

  Shirley TannerNov 26, 2025
  If your KitchenAid Ice Maker will not make ice, the water reservoir is full, and the evaporator is cold but producing only a thin, partial, irregular, or no ice slab, several issues could be at play. A seeping water valve with a hot condenser may be the cause, necessitating replacement of the water valve. A partial refrigerant leak or restriction (indicated by a U-shaped slab) may require checking for leaks/restrictions and repairing or replacing the defective component. Other potential causes include a blocked condenser or stalled fan motor (clean the condenser or repair/replace the motor), a tube not attached to the outlet of the recirculation pump (reattach the tube), a defective recirculating pump (repair or replace the pump motor assembly), or a partially blocked water distributor (cl...
