Understanding the Problem
If the ice maker in your Whirlpool WRF535SMDM00 has stopped making ice, the root cause can be mechanical, electrical, or related to the water supply. The ice maker may receive power but not cycle, or it may not fill because the water inlet valve is blocked, failed, or the water line is frozen. Temperature problems in the freezer (too warm) or a clogged/old water filter can also prevent ice production. Diagnosing this problem starts with confirming freezer temperature and whether the ice maker is getting the correct signals. Some failures are simple — a tripped arm, a frozen fill tube, or a clogged filter — while others require replacing the ice maker assembly, inlet valve, or control components. Follow safe troubleshooting steps and verify parts by your refrigerator's exact model before ordering replacements.
Common Symptoms
No ice made over 24–48 hours, ice maker not cycling, water not entering the ice maker, small or hollow ice cubes, freezer temperature higher than 0°F (-18°C), audible buzzing/clicking from the inlet valve.
Common Causes
- Faulty ice maker assembly/module (motor, switch, or harvest heater failure)
- Defective or clogged water inlet valve preventing water fill
- Frozen or blocked water fill tube or kinked water line
- Clogged/old water filter restricting flow
- Freezer too warm (thermostat/evaporator issue) or faulty thermistor/temperature sensor
- Ice maker shut off arm in the up/off position or jammed with ice

Helpful Repair Tip
Temporarily remove the ice maker and reach the fill tube; try to blow water through it or run a short manual harvest cycle (if model supports it). Measure 120VAC at the ice maker harness during a fill/cycle to confirm whether the inlet valve or the ice maker module is at fault.
Frequently Asked Questions
How do I test if the ice maker itself is bad?
Check that the freezer is cold enough (0°F / -18°C). Manually cycle the ice maker (if it has a test pin/button) or watch for a harvest cycle; listen for motor or heater activity. Use a multimeter to check for 120VAC at the ice maker harness during a fill/cycle. If the ice maker receives power but doesn't run, the ice maker assembly is likely defective and should be replaced.
Could a clogged water filter cause no ice?
Yes. A clogged or overdue water filter reduces water flow to the inlet valve and can prevent the ice maker from filling. Replace the filter (or bypass it briefly for testing) to see if ice production resumes. Always replace with a compatible filter and follow the manufacturer's instructions when reinstalling.
