Understanding the Problem
Brief explanation: The ice maker in a Roper RS22AGXT0OO is a modular assembly that fills, freezes and ejects ice. When it stops making ice or fills too little/too much, the root cause is usually one of: lack of water supply, a bad water inlet valve, a failed ice maker module/motor, a clogged/iced fill tube, a failed heater/thermostat on the mold, or an electrical/wiring fault. Step-by-step diagnostic and repair steps: 1) Safety and preparation - Unplug the refrigerator and shut off the water supply to the unit. Have a multimeter, nut driver/screwdriver set, and towels ready. Wear gloves and eye protection. 2) Visual inspection - Open the freezer, remove the ice bin and inspect the ice maker for obvious damage, cracked gears, heavy scale/ice build-up in the mold or ice sheet, or loose/disconnected wiring. 3) Check water supply and fill tube - Confirm the water shutoff valve is fully open. Remove the ice bin and manually activate the ice maker test (see step 6) and watch for a water fill. If you see no water or a tiny trickle, move to the inlet valve test. - Inspect the fill tube (from water valve to freezer) for ice blockage. If frozen, thaw the tube with a hair dryer (low setting) until water flows normally. 4) Test the water inlet valve - Locate the valve at the rear bottom of the refrigerator. With the fridge plugged in and water on, put the ice maker into fill/test mode (step 6). If no water flows but the valve is receiving voltage during fill, the valve is faulty and must be replaced. - Use a multimeter to check the inlet valve solenoid coil continuity (should not be open). Replace valve if open or if it has voltage but no water flow. 5) Test the ice maker motor/module and heater - Many Roper/Whirlpool-style ice makers have a test/harvest switch. Enter harvest/test mode and watch the sequence: heater (if equipped) should warm, mold should rotate/eject, and fill should occur. If the motor does not run or the unit does not advance through cycles, suspect the ice maker assembly or its control module. - Check continuity of the ice maker motor terminals and mold heater (if present). Replace the ice maker assembly if motor/heater are open or the control module is dead. 6) How to run a manual test cycle (general for Whirlpool/Roper style modules) - Locate the test button or switch on the ice maker. With the freezer door open, press and hold the test button for 5–10 seconds or until you hear the motor run. The unit should perform a harvest and then a fill. If there is no response, check wiring and voltage to the ice maker harness (expect ~120VAC during harvest/fill depending on model). 7) Replace suspect parts - If the inlet valve, ice maker assembly, or fill tube is identified as bad, follow the replacement steps below. Always replace with the correct OEM or a known-compatible replacement for RS22AGXT0OO. 8) Basic replacement steps (ice maker assembly) - Turn power off and water off. - Remove the ice bin and locate the two mounting screws holding the ice maker in place; remove them. - Pull the ice maker forward slightly, disconnect the wire harness connector, and remove the unit from the freezer. - Install the new ice maker by reversing removal: connect the harness, seat the unit, fasten mounting screws, restore water and power, and run a test cycle. 9) Check for leaks and operation - After replacement, observe the first fill; confirm correct fill volume and no leaking connections. Wait through one freeze/fill cycle (several hours) to confirm proper ice production. Safety note: Always disconnect mains power before removing or working on the ice maker assembly or water valve and shut off the water supply when disconnecting water lines. If you are not comfortable testing live voltage or replacing water-line components, hire a qualified appliance technician.
Common Symptoms
No ice production, underfilled mold, continuous water running, ice maker not advancing, ice bin full of small wet clumps or watery/soft ice.
Common Causes
- Closed or blocked water supply / frozen fill tube
- Failed water inlet valve (doesn’t open to fill)
- Bad ice maker module/motor or mold heater/thermostat

Helpful Repair Tip
To confirm the ice maker module is bad: put the unit into its test/harvest mode. If the unit receives voltage but the motor/heater doesn't run, the ice maker assembly (control/motor) is almost certainly faulty and should be replaced.
Frequently Asked Questions
How do I run a test or harvest cycle on my Roper ice maker?
Most Roper/Whirlpool-style ice makers have a test or harvest button on the module. With the freezer door open, press and hold that button for 5–10 seconds until the unit begins a cycle. You should hear the motor and possibly a heater. If nothing happens, check the wiring and for voltage to the ice maker. Refer to your service manual for the exact test procedure for RS22AGXT0OO.
Can I replace the ice maker myself, and how long does it take?
Yes—if you are comfortable with basic hand tools, shutting off water, and plugging/unplugging the refrigerator. Typical replacement takes 15–45 minutes: remove ice bin, unmount the old module, disconnect the harness, install the new module, reconnect, restore water and power, then run a test. If you must handle live-voltage checks or suspect a refrigerant/complex electrical issue, call a technician.
