Roper Refrigerator Ice Maker Not Working: Troubleshooting... | appliancefaults.com

Technical Background:

The ice maker operates based on signals from the main control unit (MCU). The MCU controls the water inlet valve, which supplies water to the ice maker mold. The ice maker module then controls the freezing and ejection process. If the ice maker doesn't receive water or the module fails, ice production stops. The water dispenser operates on a separate circuit and valve, so it can function independently.

Symptoms:

The ice maker in your Roper refrigerator is not producing ice, but the water dispenser is working fine. This indicates that the main water supply to the fridge is functional, but the ice maker-specific components are not operating correctly.

Possible Causes:

Frozen fill tube
Defective ice maker module
Low water pressure
Faulty water inlet valve (ice maker side)
Ice maker arm in the 'off' position
Clogged water filter

Solution:

1

Verify water pressure to the refrigerator. It should be at least 20 PSI.
2

Check the ice maker fill tube for ice blockage. Use a hair dryer on low to melt any ice.
3

Inspect the ice maker module. Manually cycle the ice maker by locating the test port (usually on the right side of the module) and using a jumper wire to short the T and H terminals for a few seconds. See if the ice maker initiates a harvest cycle.
4

Test the water inlet valve (ice maker side) for continuity using a multimeter. A reading of around 300-500 ohms is typical. If there is no continuity, replace the valve.
5

Confirm 120V AC is reaching the water inlet valve during the ice maker fill cycle. Use a multimeter to check the voltage.
6

Replace the water filter. A clogged filter can reduce water pressure to the ice maker.
7

Ensure the ice maker arm is in the 'on' or 'down' position.

Safety Warning:

Disconnect the refrigerator from the power source (unplug it or turn off the breaker) before performing any repairs. Water and electricity can create a dangerous shock hazard. Ensure Lock-Out/Tag-Out (LOTO) procedures are followed to prevent accidental re-energizing of the circuit.

Prevention:

Replace the water filter every 6 months. Periodically check the ice maker fill tube for ice buildup. Avoid setting the freezer temperature too low, as this can cause excessive freezing.

Expert Tip:

If the ice maker is cycling but not filling with water, suspect a partially blocked fill tube or a very weak water inlet valve. Sometimes, scale buildup can restrict water flow even if the valve has continuity. Try flushing the valve with vinegar to remove mineral deposits.

Frequently Asked Questions

•How do I access the water inlet valve on my Roper refrigerator?

The water inlet valve is typically located at the back of the refrigerator, near the bottom. You'll usually need to remove the rear access panel using a 1/4-inch nut driver or a Phillips head screwdriver. Disconnect the water lines and electrical connectors before removing the valve.

•What voltage should I expect to see at the water inlet valve during the ice maker fill cycle?

You should see approximately 120V AC at the water inlet valve terminals during the brief period when the ice maker is calling for water (the fill cycle). Use a multimeter set to AC voltage to measure this. Be extremely careful when working with live voltage.

•How can I test the ice maker module if I don't have a jumper wire?

You can use a small insulated screwdriver or a bent paperclip instead of a jumper wire. Just be sure to only momentarily touch the T and H terminals together. Prolonged contact can damage the ice maker module.
