Whirlpool Ice Maker: not shutting off

Professional Repair Guide

What is this symptom?

Is your Whirlpool ice maker continuously producing ice, even when the bin is full? This issue may be caused by a stuck shut-off arm, faulty sensors, or a defective control module. Without proper intervention, your ice maker might overflow, creating a mess in your freezer.

Urgency: Medium

Important Tips for Whirlpool Models

Whirlpool refrigerators often use a mechanical feeler arm or control arm that must be correctly positioned and free to pivot to signal shut‑off.

Possible Causes

Stuck or misaligned shut‑off (feeler) arm

How to Identify: Ice maker continues producing even when bin is full; the shut‑off arm stays in the down position or doesn’t move freely when nudged. Inspect for ice obstruction or freezing around the arm.

Part: Mechanical shut‑off arm / feeler arm

Faulty ice level sensors (optical or electronic)

How to Identify: No mechanical feeler arm but ice maker never stops even with a full bin; sensors or ‘eyes’ coated with frost or misaligned. Cleaning or reseating bin may help diagnose.

Part: Optical sensors / ice level detection sensor

Failed shut‑off switch / control module

How to Identify: Ice maker doesn’t respond to shut‑off arm or sensor movement; reset doesn’t stop cycles. Requires testing of control module for completion of sensor signals.

Part: Ice maker control module / shut‑off switch

Stuck‑open water inlet valve

How to Identify: Continuous feed of water into ice maker, potential water overflow, and signs of water dripping. Ice maker doesn’t stop cycling even when full.

Part: Water inlet valve

DIY Solutions

Inspect and Free Shut‑Off Arm

Easy 10–20 minutes

Tools Needed: Warm cloth, Hairdryer (low)

Remove the ice bin to access the ice maker area.
Locate the shut‑off arm (metal or plastic wire) and gently move it up and down to see if it’s stuck.
If frozen or stuck, use a warm cloth or gentle warm air to melt ice around pivot points.
Ensure the arm pivots freely without obstruction, re‑seat arm if misaligned, then replace ice bin and monitor operation.

⚠️ Safety First: Do NOT use high heat or direct flame on plastic parts.

Clean Optical Sensors

Moderate 15–30 minutes

Tools Needed: Soft cloth, Cotton swabs

Remove the ice bin.
Locate sensor ‘eyes’ at bin area if your model uses optical sensors.
Gently clean the sensor lenses with a soft cloth or cotton swab to remove frost, dirt, or debris.
Make sure the ice bin is properly seated and aligned, then test operation.

⚠️ Safety First: Be gentle to avoid scratching sensor lenses.

Reset Ice Maker Module

Easy 5–10 minutes

Locate the ice maker reset button (if present) and press and hold for a few seconds.
If there’s no reset button, unplug the refrigerator for 1–3 minutes and plug it back in.
Allow the ice maker a full cycle and observe if it now shuts off appropriately.
