WR49X31524 GE ICEMAKER OEM
WR49X31524 GE ICEMAKER OEM is an OEM icemaker assembly used in General Electric refrigerators; it is a modular ice-making component that houses the ice mold, ejection mechanism, fill interface and the electromechanical controls required to produce and dispense cubed ice. As a factory-designed replacement part, it includes the housing, motor/drive or harvest actuator, thermostat or sensor elements and the electrical connector that integrates the unit with the refrigerator’s control wiring and water supply fittings.
Inside the appliance, the icemaker controls timed water fills into the mold, freezes water to form ice, and ejects the finished cubes into the storage bin. It interacts directly with the refrigerator’s water inlet valve and supply line, the control board or timer that initiates harvest and fill cycles, and temperature-sensing elements (thermostat, thermistor or optical sensor) that confirm freeze and harvest conditions. Mechanically it couples to the ice bin and fill tube; electrically it receives control signals and provides status through switches or sensors, so faults in any of these subsystems (water supply, valve, harness, sensor, or drive mechanism) will affect ice production or cause leaks and overflows.

Function and Role of the Icemaker Assembly in GE Refrigerators
The WR49X31524 GE ICEMAKER OEM is a modular ice-making assembly that performs ice production, harvest, and ejection within compatible GE refrigerator freezers. Mechanically, the assembly contains a water-fill cup, a molded ice tray, an ejector/gear train driven by a small synchronous motor, and either a temperature-sensing thermostat or a sensor that determines when the ice is ready for harvest. Electrically, it interfaces with the refrigerator control board and the water inlet valve so that a timed fill occurs only when the mold is cold enough; a heater or defrost cycle is then activated briefly to loosen cubes and allow the ejector blades to rotate and drop cubes into the bin. Proper operation therefore depends on correct alignment of the fill tube and mold, intact drive components, and the expected electrical signals from the freezer control circuitry.
Technicians diagnosing or replacing this assembly should understand typical behaviors and failure modes: intermittent fills commonly point to a stuck or clogged fill tube or a faulty water valve, while harvest failures usually indicate a bad motor, broken gears, or a failed thermostat/heater. Compatibility considerations include the harness connector type, mounting tab locations, and the orientation of the water inlet – the WR49X31524 unit is intended as a direct-replacement option for specific GE models but should be verified against the appliance’s harness and mounting before installation. Practical service steps include visually inspecting the mold and fill path for ice obstruction, confirming continuity of motor and thermostat elements, and verifying that the control board provides the expected drive signal during a harvest cycle; replacing the module and verifying a complete fill/harvest cycle restores normal operation in most mechanical failure cases.
- Key behaviors: timed fill, temperature-sensed harvest, heater/defrost assist, mechanical ejection.
- Common symptoms: no fill, continuous fill, no harvest/ejection, small or misshapen cubes.
- Compatibility checks: connector type, mounting tabs, fill tube alignment, and model fitment.

How the WR49X31524 GE ICEMAKER OEM Operates Within the Appliance: mechanical, Electrical, and Control Principles
The WR49X31524 GE ICEMAKER OEM is a modular, drop-in harvest-style ice maker that combines a molded freezing tray, an electric mold heater, an ejector motor/gearset, and a small temperature-actuated thermostat into a single assembly.Mechanically, the unit fills a partial-volume mold from the refrigerator’s water valve, holds the water while the evaporator freezes it into individual cubes, then uses a timed or thermostat-based control to activate the heater and the ejector motor to release ice into the bin. Electrically, the ice maker is driven by the refrigerator control board through a multi-pin connector: one circuit typically energizes the heater during the harvest phase while another powers the motor for ejection; an input from a thermostat (or internal sensor) confirms the mold temperature and prevents premature harvest.In practical service, fit and pin compatibility with the appliance wiring harness are critical-WR49X31524 matches the factory mounting and terminal layout on compatible GE models, reducing wiring adaptation when replacing a failed unit.
- Primary components: fill cup/solenoid interface, mold heater, temperature thermostat/sensor, ejector motor and gearset, wiring harness connector.
- Cycle phases: fill → freeze → sense (thermostat) → harvest (heater + motor) → refill.
- Common diagnostics: heater continuity, motor stall/noise, presence of control voltage during harvest, proper fill volume and alignment.
| Item | description |
|---|---|
| Thermostat / Sensor | temperature-actuated switch that signals completion of the freeze cycle and blocks harvest until setpoint reached. |
| Mold Heater | Low-resistance element that briefly warms the mold surface to loosen ice during harvest. |
| Ejector Motor | small synchronous/BLDC motor with gearbox that rotates ejector blades to push cubes out of the mold. |
| Connector / Terminals | Multi-pin interface to the appliance control board (power,neutral,and sensor/feedback lines). |
functionally, troubleshooting and replacement require attention to both mechanical alignment and electrical behavior: a heater open-circuit, seized ejector gear, or missing control voltage during the harvest interval will produce similar symptoms (no ice release), so isolating the fault with continuity checks and live-voltage verification at the harness is standard practice. For example, a technician may observe normal freeze formation but no harvest; measuring continuity across the heater and checking for the expected control voltage at the heater and motor terminals during a commanded harvest cycle helps distinguish a component failure from a control-board issue. When selecting WR49X31524 as a replacement, confirm the appliance model compatibility and terminal layout-using the OEM part preserves the original mechanical mounting and electrical pinout, minimizing modification and ensuring expected cycle behaviour in service.
Common Failure Symptoms and Diagnostic Indicators for WR49X31524 Icemaker Malfunctions
The WR49X31524 GE ICEMAKER OEM functions as the electromechanical controller that meters water into the mold, senses mold temperature, initiates the harvest cycle, and ejects finished cubes. In normal operation the module times a fill, allows the mold to freeze, then switches to harvest (activating either a low-voltage thermostat or a heater element depending on design) and runs the ejector motor to deliver cubes to the bin. Compatibility with the refrigerator’s harness and mounting pattern matters: the OEM unit uses the factory plug configuration and timing characteristics designed for specific GE models, so swapped or non‑matching replacements can produce incorrect fill volumes, mis-timed harvests, or electrical mismatches that present as failure symptoms described below.
- No ice production or dramatically reduced yield (can indicate failed motor, stuck fill cup, or power absence at the harness).
- Partial fills,small or hollow cubes (suggests short fill time,low water pressure,or intermittent valve operation).
- Continuous water flow into the tray or overflowing (often a stuck/failed water inlet valve or defective fill switch on the icemaker).
- Motor hums or receives voltage but does not turn (mechanical seizure or broken drive components).
- Ice remains frozen in the mold and never ejects (failed harvest heater/thermostat or inadequate freezer temperature).
diagnosing faults requires observing cycle behavior and using a multimeter to verify electrical and thermal responses at the icemaker harness.Measure supply voltage at the module during a known harvest or fill event to confirm the refrigerator is delivering power; if voltage is present but the motor or heater shows open circuit on resistance checks, the icemaker assembly is the likely fault. Conversely, if the module is getting no control voltage, trace upstream to the main control board, door switches, or water valve. Practical examples: if the mold never reaches freeze temperature, confirm ambient freezer temperature and thermostat continuity before replacing the icemaker; if the motor receives 120 VAC during eject but does not rotate, replace the icemaker motor/gear assembly rather than the water valve.
| Item | Description |
|---|---|
| Voltage at harness | Verify mains‑level control voltage during fill/harvest; presence indicates module or mechanical fault,absence points to upstream control or wiring. |
| Thermostat/thermistor response | Check for continuity change as temperature goes below freezing; no change suggests failed temperature sensor or open internal thermostat. |
Replacement Considerations, Model Compatibility, and Step‑by‑Step Installation procedures
The WR49X31524 GE ICEMAKER OEM is a modular ice-producing assembly that controls the water-fill, freezing, and harvest phases through a cam-driven motor and temperature sensing element. In operation, the module times the water inlet valve to deliver a measured fill into the mold, monitors mold temperature to determine freeze completion, and activates the harvest heater or motor armature to release cubes into the bin. Compatibility depends on matching the mounting footprint, electrical connector pinout, and water-inlet configuration; technicians should verify the harness type and mounting hole pattern against the existing unit before ordering a replacement to avoid fitment or wiring mismatches.Practical examples include units that replace failed motors or thermostats in models with the same chassis layout and those used to restore cycling in refrigerators that show partial fills or intermittent harvest cycles.
Replacement requires basic appliance skills and common hand tools; follow safe-practice steps such as removing power and shutting off the water supply, then confirm connector and valve orientation before disassembly. Typical installation steps include bin removal, access-panel removal, disconnecting the electrical harness and water line, unfastening the icemaker from its bracket, transferring any retained components (e.g., fill cup or shield), and installing the new assembly with attention to alignment of the ejector blades and sensor location.After installation, restore power and water, initiate a manual fill or test cycle if available, observe one complete fill-freeze-harvest sequence, and check for leaks and correct cube release. Common post-replacement checks: ensure the ice level arm (if present) is set correctly, verify the inlet valve seats fully, and confirm the motor runs through a full harvest without stalling.
- Power off and water off before starting; release trapped pressure in the water line.
- Document connector orientation and take photos if harness routing is complex.
- Swap the unit, verify secure mounting and correct torque on fasteners, then run a test cycle.
- Inspect for leaks at the inlet and proper cube ejection into the bin.
| Item | Description |
|---|---|
| Operating voltage | Typically 120 VAC with motor/thermostat circuits; confirm with multimeter before connection. |
| Mounting | bracket and screw pattern must match refrigerator cavity; foam or gasket alignment affects fill cup seating. |
| Electrical connector | Verify pin count and function (motor, heater, switch) to avoid cross-wiring. |
| Water inlet | Standard 1/4″ compression or specific fitting; ensure hose seating and use thread seal if specified. |
| Sensor type | Bi-metal or electronic thermistor; replacement should match original sensing method for proper cycle timing. |
Q&A
What is the WR49X31524 icemaker and which refrigerators is it compatible with?
The WR49X31524 is an OEM replacement icemaker assembly produced for GE refrigerators. It replaces the factory icemaker in a range of GE/Hotpoint models that use the same mounting and electrical harness. Compatibility depends on your refrigerator model number and the original icemaker part number - always verify the part cross‑reference for your exact refrigerator model before purchasing.
What are the most common symptoms that the WR49X31524 needs to be replaced?
Common symptoms include: no ice production, the motor not turning during a test cycle, ice being formed but not being ejected (harvest failure), continuous or overfilling of the ice mold, or visible mechanical damage. Before replacing, check water supply, water inlet valve and filter, freezer temperature, and wiring to rule out those causes.
How do I test the icemaker to determine if the WR49X31524 is bad?
First, set the freezer to the proper temperature (around 0°F / -18°C) and confirm a working water supply. Use the icemaker’s test switch (if present) or follow the refrigerator’s diagnostic procedure to initiate a harvest cycle. If the motor does not run, unplug the refrigerator and use a multimeter to check for voltage at the icemaker harness during a call for harvest (household voltage ≈ 120 VAC in the U.S.). Also check continuity of motor and heater circuits per the wiring diagram. If power is present but the icemaker does not operate, the assembly is likely defective.
What basic troubleshooting should I do before replacing the WR49X31524?
1) Verify the water line is open and the inlet valve is functioning (nozzle should fill during a fill cycle). 2) Check/replace the water filter if low water flow is suspected. 3) Ensure freezer temperature is cold enough (0°F / -18°C). 4) Inspect the ice mold for jams or ice bridges. 5) Run the icemaker test cycle to observe whether motor, fill valve, or ejector operate. If these checks point to an icemaker mechanical/electrical failure, replacement is appropriate.
How do I install the WR49X31524? Is it a challenging DIY repair?
Installation is a moderate DIY task. General steps: disconnect power and, if applicable, the water supply; remove the bin and old icemaker; disconnect the harness and mounting screws; install the new icemaker, secure mounting screws, reconnect the harness, restore power and water, and run a test cycle.
