IG
Whirlpool Refrigerator
Severity: MinorWhat Does This Error Mean?
The IG error on a Whirlpool refrigerator indicates an ice maker problem — the ice maker is not producing ice or has detected an issue with the ice-making cycle. This could be as simple as the ice maker being turned off or the water supply being interrupted. Start with the basics before assuming a part has failed.
Affected Models
- WRS325SDHZ
- WRF535SWHZ
- WRS571CIHZ
- WRB322DMBM
- Most Whirlpool side-by-side and French door models with ice maker
Common Causes
- Ice maker is switched off via the on/off switch or arm
- Water supply line to the refrigerator is kinked or turned off
- Water inlet valve is clogged with sediment and not letting water through
- Freezer temperature is too warm (above 10°F) for ice production
- Ice maker module or thermostat has failed
How to Fix It
-
Check that the ice maker is turned on.
Many Whirlpool models have a power switch or wire arm on the ice maker itself. Make sure the arm is in the down position (on) and any power switch is set to On.
-
Check the water supply line at the back of the refrigerator.
Make sure the shutoff valve on the water line is fully open and the line is not kinked or pinched behind the fridge.
-
Verify the freezer temperature is set correctly.
Ice makers require a freezer temperature of 0°F to 5°F (-18°C to -15°C) to make ice. If the freezer is set too warm, ice production stops.
-
Reset the ice maker.
Locate the reset button on the ice maker module (often on the underside or back). Press and hold it for 10 seconds. This forces the ice maker to run a test cycle.
-
Allow 24 hours after reset before expecting ice.
Even after a successful fix, the ice maker needs time to produce and fill the first batch of ice. Give it a full day before judging results.
When to Call a Professional
If water supply is fine and the ice maker is turned on but IG persists, the ice maker module or inlet valve needs testing. Expect repair costs of $100–$200 depending on which component is faulty.
Frequently Asked Questions
Why did my Whirlpool ice maker suddenly stop working?
The most common reasons are the ice maker being accidentally turned off, a kinked water line, or a clogged water filter. Check these simple things first before assuming a part has broken. A clogged water filter is very common — filters should be replaced every 6 months.
How long does it take a Whirlpool ice maker to make ice?
After the ice maker is first installed, connected to water, and the freezer is cold, expect 24 hours before the first ice is produced. After that, most Whirlpool ice makers produce about 120 cubes per day under normal conditions.
Can a dirty water filter stop my ice maker?
Yes — a clogged filter reduces water pressure to the ice maker so much that it cannot fill properly. Whirlpool recommends replacing the water filter every 6 months. A new filter often restores ice production immediately.
