Understanding the Problem
Brief explanation: The ice maker in a Roper RS22AGXT000 (top-freezer style) either stops making ice, makes small or hollow cubes, overfills/leaks, or runs continuously. The common failure points are the water inlet valve, the ice maker module/assembly, the fill tube (frozen or clogged), the water filter, temperature problems, or an electrical/control fault. Step-by-step diagnostic and repair instructions: 1) Verify basic conditions - Set freezer temperature to 0°F (-18°C) and wait 24 hours. Ice makers usually need the freezer this cold to produce properly. - Make sure the water supply is turned on to the refrigerator and the water line is not kinked. - If your fridge has a water filter, check its age. A clogged filter can reduce fill pressure. 2) Observe symptoms and isolate problem type - No ice at all, no harvest: could be electrical, switch, or module failure. - No fill/low fill: likely low water pressure, clogged/frozen fill tube, or faulty inlet valve. - Continuous fill/overflow: inlet valve stuck open or ice maker stuck in fill position. - Small/hollow cubes: freezer too warm or intermittent fill/low water pressure. - Leaks under fridge or in freezer: inlet valve leak or cracked water line. 3) Quick tests you can do without parts - Manually advance the ice maker to a harvest cycle (use the small gear or push the advance arm, depending on style). If it cycles and ejects old ice, the motor works. - During a manual harvest, watch the fill: the water should run into the mold for ~6–10 seconds. No water = inlet valve or water supply issue. - Listen when the ice maker should be filling: you should hear a click when the valve opens. 4) Check water pressure and supply - Remove or bypass the water filter and test. If ice size/amount improves, replace the filter. - Check household water pressure. Low pressure reduces fill volume. 5) Inspect the fill tube - With the freezer off for a few minutes, check the fill tube from the back of the freezer to the ice maker for ice blockage. Thaw any ice with a hair dryer on low or allow the freezer to defrost. 6) Test the water inlet valve - Unplug fridge, pull it away, and locate the water inlet valve at the back lower left. Test the valve solenoid with a multimeter for continuity. If the valve has no continuity or doesn't open when 120VAC is applied (fridge energized and calling for water), replace it. 7) Test the ice maker assembly/module - With the ice maker powered, check for 120VAC (or appropriate low voltage on some models) at the ice maker’s supply when it should be calling for water. If voltage is present and valve doesn't open, replace valve. If no voltage, replace ice maker module/board or wiring harness. - If the ice maker motor does not turn during a manual advance or at the start of a cycle, the ice maker assembly is faulty and should be replaced. 8) Replace common parts (basic replacement instructions) - Ice maker assembly replacement: a) Unplug refrigerator. b) Open freezer and remove the ice bucket and any trim. Locate mounting screws holding the ice maker to the freezer wall. c) Remove screws, gently pull ice maker forward a few inches and disconnect the wiring harness. Some models have a quick-disconnect water tube — unplug that too if present. d) Install new ice maker: connect harness and water tube, seat mount, secure screws, reinstall bucket, plug in fridge, and test by advancing to a harvest and watching for a fill. - Water inlet valve replacement: a) Unplug refrigerator and shut off house water supply. b) Pull fridge away and remove lower access cover to reach the valve. c) Disconnect the water lines (catch water), unplug the electrical connector, and remove mounting screws. d) Install new valve, reconnect water lines, restore water, check for leaks, plug in refrigerator and test. 9) Final tests and calibration - After replacement, manually advance the ice maker to force a harvest and fill. Wait the next 6–8 hours for the first cycle to complete and check ice production over 24 hours. Safety note: Always unplug the refrigerator (or switch off power at the breaker) before testing electrical components or replacing parts. Shut off the water supply before disconnecting water lines. Use eye protection and work on a stable surface.
Common Symptoms
No ice production, small or hollow cubes, ice maker continuously runs or overfills, visible leaks from the ice maker area, or ice with poor taste/odor.
Common Causes
- Faulty water inlet valve (won't open or leaks)
- Failed ice maker module/assembly (motor, switch, or control fault)
- Frozen or clogged fill tube or a blocked water filter
- Freezer temperature too warm (thermostat or door seal issue)

Helpful Repair Tip
To confirm the ice maker module is faulty: advance it into a harvest cycle manually and watch for a fill. If the module turns and you get no water but the inlet valve has voltage during the fill, the valve is bad. If there is no voltage at the ice maker when it should call for water, replace the ice maker assembly.
Frequently Asked Questions
How can I reset the ice maker on a Roper RS22AGXT000?
Most Roper/Whirlpool-style ice makers reset by either pressing a recessed reset button on the module for 5–10 seconds or by manually advancing the ice maker into a harvest cycle (rotate the gear or lift/lower the arm depending on style). If reset does not restore function, follow the diagnostic steps above to test the valve and module.
Can I replace just the ice maker or do I need to replace the whole kit?
Often you can replace just the ice maker assembly and/or the inlet valve — those are the most common failures. However, verify whether your model uses a separate fill tube, harness, or mounting brackets; some sellers offer a full kit (ice maker + harness + valve) which guarantees compatibility and can save troubleshooting time. Always verify part numbers against your refrigerator’s model and serial plate before ordering.
