Not making ice in KitchenAid refrigerator

Refrigerator & Freezer Repair
1

Brand:KitchenAid
Model Number:KRSC703HPS00
Main Symptom:No ice
What happens & when:

Water dispenser works fine

No error codes in diagnostics

Have defrosted fill tube

Replaced ice maker

Freezer temp is around 0F

Most descriptions of the 2 water valves indicate failure if not getting water at the ice maker OR water dispenser. I am getting water at the dispenser. Just not in the ice maker.

Thank you

Thanks for the detailed information! Since your Whirlpool KRSC703HPS00 has a working water dispenser, the freezer is around 0°F, and you’ve already replaced the ice maker and defrosted the fill tube, I would concentrate on the ice maker water supply circuit before replacing anything else.

One important point: A working water dispenser does not rule out a bad water inlet valve. The refrigerator uses separate water flow paths for dispensing water and filling the ice maker. It’s possible for one to work while the other fails.

Here’s how I would narrow it down.

1. Check whether the ice maker is calling for water

First, we need to determine whether the ice maker is actually requesting a fill.

  • Make sure the ice maker is turned on.
  • Confirm the ice bin is properly installed.
  • Run the ice maker harvest test through diagnostics, if available.
  • Listen for the ice maker cycling and then for the water valve to activate.

If the ice maker completes its harvest but no water enters, the next step is checking the water valve.

2. Test the ice maker water valve

The water inlet valve contains an electrically operated solenoid that opens when the control calls for water.

Live Power Warning: This test involves 120-volt AC electricity. Only perform it if you’re comfortable using a multimeter around live electrical connections.

During an ice maker fill command:

  1. Set your multimeter to AC volts.
  2. Identify the valve solenoid supplying the ice maker using the model’s wiring diagram.
  3. Carefully measure voltage across that solenoid’s two terminals while the ice maker is requesting water.

Here’s what the results mean:
Reading during fill
What it indicates
Approximately 120 VAC
Valve is being energized. Suspect the valve itself, a restriction, or a frozen fill tube.
0 VAC
Valve isn’t receiving a fill command. Check wiring, control, and ice maker communication.
Voltage appears briefly
May be normal because the fill cycle lasts only a few seconds.

The important part is taking the reading during an actual fill command, not while the refrigerator is sitting idle.

3. Use the diagnostic water fill test

Many Whirlpool/KitchenAid refrigerators in this family have Service Test 45, which activates the ice maker fill valve, and Service Test 57, which checks ice maker harvesting. Verify these test numbers against the tech sheet for your specific unit.

If Test 45 is available, this is the test I would run first. It allows you to check whether the valve is receiving power without waiting for a normal ice-making cycle.

4. Check the two water valves separately

Parts information for the KRSC703HPS00 identifies both a primary water inlet valve and a separate valve assembly. Either can affect the ice maker supply, depending on where the restriction or electrical failure occurs.

If the ice maker valve receives the proper voltage but no water flows, the next step is to check for water at the valve outlet. With power and water shut off, the outlet tubing can be disconnected and directed into a container for a controlled fill test after everything is safely positioned.

If water comes out of the valve but never reaches the ice maker, suspect a restriction or refreezing in the tubing.

What I would like to know next

You mentioned there are no diagnostic error codes. That’s helpful, but I’d like to know two more things:

  1. Have you run the ice maker water fill test (Test 45, if available), and did any water enter the ice maker?
  2. When you defrosted the fill tube, was it actually blocked with ice, or were you thawing it as a precaution?

Those answers should help us determine whether we’re dealing with a defective valve, a recurring frozen fill tube, or a problem with the electrical fill command. I wouldn’t purchase either valve until we’ve narrowed that down.
