How to Fix a Whirlpool Ice Maker That Stopped Making Ice

Most dead ice makers trace to a raised feeler arm, a frozen fill tube, a closed water valve, or a clogged filter.

Low risk — no live power or gas involved once unplugged.

Tools

Step 01
Check the feeler arm or switch
Lower the wire feeler arm or set the ice maker switch to On. A raised arm tells the module the bin is full and stops production.
Step 02
Verify freezer temperature
Confirm the freezer holds 0F to 5F. Above about 10F, the mold never chills enough to trigger a harvest cycle.
Step 03
Replace the water filter
Swap a filter older than six months. A clogged filter drops line pressure below what the fill valve needs to admit water.
Step 04
Thaw the fill tube
Aim a hair dryer on low at the small fill tube entering the back of the ice maker until the ice plug melts, catching drips with a towel.
Step 05
Force a harvest cycle
Press the ice maker test button, or cycle power. Water should fill the mold within about a minute and drop cubes within a few hours.

Expect the first harvest within about 90 minutes and a full bin in roughly 24 hours.
