1129313 Whirlpool Refrigerator Ice Maker Kit Round Plug is an electrical connector assembly used with Whirlpool ice maker modules; it is indeed a multi-pin, round-style plug and associated pigtail that provides the mechanical and electrical interface between the ice maker subassembly and the refrigerator wiring harness. The part generally includes a keyed mating connector and insulated terminals designed for line-voltage, low-voltage control signals, and sensor/power conductors specific to ice maker operation.
Inside the appliance, the round plug transmits power and control signals required for the ice maker’s motor, harvest heater, fill valve actuator, and temperature sensor, and it provides the physical connection point for diagnostic communication with the refrigerator control board. The connector thus interacts directly with the main control board, water inlet valve circuit, thermistor or temperature-sensing element, and the ice maker’s internal switch/microcontroller; its integrity affects signal continuity, grounding, and sealing against moisture and corrosion in the freezer compartment.
This article will explain the plug’s functional role and typical pinout relationships, outline model compatibility and where the component is normally located, and describe common failure symptoms such as loss of ice production, continuous fill, intermittent cycling, or visible corrosion. It will also cover practical troubleshooting steps (visual inspection, continuity and voltage checks during cycle conditions), diagnostic considerations for related subsystems, and key replacement considerations including correct part matching, connector orientation, retention hardware, and basic safety precautions for power and water isolation.

Function and Role of the Ice Maker round Plug in Whirlpool Refrigeration Systems
The 1129313 Whirlpool Refrigerator Ice Maker Kit Round Plug functions as the primary electrical and mechanical interface between the refrigerator wiring harness and the ice maker assembly. Its round, keyed housing organizes and secures multiple conductors that carry power and control signals (fill-valve actuation, harvest/heater command, and sensor/thermistor feedback) while providing strain relief and a moisture-resistant mating surface to reduce corrosion and intermittent connections.in practical installations this plug allows a replacement ice maker to mate directly with the factory harness without splicing, provided the pinout and housing geometry match the refrigerator model.
- Common failure symptoms: no ice production, intermittent harvest cycles, continuous fill, or complete loss of power to the ice maker.
- Speedy diagnostics: perform a visual inspection for corrosion or heat deformation, check continuity across pins, and measure voltage on the corresponding pins during a known cycle stage to confirm proper signals.
- Installation guidance: confirm pinout compatibility with the refrigerator model, ensure the plug is fully seated and keyed correctly, and avoid cutting or splicing unless you can replicate the original wiring and insulation standards.

Technicians should treat the round plug as part of the electrical circuit when troubleshooting ice-maker faults rather than only replacing the ice maker module. In service situations where the harness shows damage or a nonstandard pinout, replacing the entire harness or using a compatible 1129313-style plug assembly can restore reliable connections and reduce future failures; when uncertain, compare the harness wiring diagram or use a multimeter to map signals prior to swapping parts. Proper seating, clean contacts, and correct orientation are frequently enough sufficient to resolve intermittent behavior without more extensive repairs.
How the 1129313 Whirlpool refrigerator Ice Maker Kit Round Plug operates Within the Ice-Making Assembly
The 1129313 Whirlpool Refrigerator Ice Maker Kit Round Plug is the circular electrical connector that links the ice-maker module to the refrigerator wiring harness. It serves as the primary electrical and mechanical interface, carrying the low-voltage supply, ground and the ice-maker control/sensor signals between the control board and the ice-making assembly. The plug’s shell is keyed to prevent incorrect insertion and maintains contact pressure on the individual pins so that the harvest cycle command, fill-valve actuation, and thermostat or sensor returns are transmitted reliably even with vibration and thermal cycling typical inside a freezer cavity.
In operation the round plug behaves as both a connector and a serviceable failure point: a clean, correctly seated plug yields predictable voltage and signal continuity and allows the ice-maker to complete fill, freeze and harvest phases as designed. Technicians verify plug health by inspecting contacts for corrosion or deformation, checking for correct mating geometry and confirming expected voltages or continuity at the mating pins during an operational cycle. Common practical checks include a wiggle test to reveal intermittent contacts, measuring DC presence on the supply pin during a call for ice, and confirming that aftermarket or swapped plugs have the same pinout before replacing. Replacing the plug with the matching OEM-style unit restores mechanical fit and correct signal routing when contact wear or environmental damage is the root cause.

Common Failure Symptoms and Electrical/Mechanical Diagnostic Indicators for the Ice Maker Round plug
The 1129313 Whirlpool Refrigerator Ice Maker Kit Round Plug is the electrical/mechanical interface that links the ice maker module to the refrigerator harness; it transmits motor/harvest commands,the fill-valve feed,sensor signals and chassis ground through a compact circular connector. Failures of this round plug typically present as loss of ice production, partial harvest cycles, or intermittent operation caused by poor contact resistance, bent or corroded pins, broken latch features, or incorrect interchange with visually similar connectors from other models. Technicians should treat the plug as both an electrical connector and a mechanical retention device: a plug that fits but has a different pinout or missing retention will produce functional faults even when it appears to be mechanically seated.
- No ice or no harvest – check for absence of supply voltage or command signals at the plug and verify continuity through each conductor.
- Intermittent operation – inspect for loose pins, fretting corrosion, and perform a wiggle test while monitoring voltage for voltage drop under load.
- Blown fuses/trips – test for short to chassis ground from individual pins using an ohmmeter.
- Physical damage/water ingress – inspect housing, latch, and insulation; replace plug if sealing or contact geometry is compromised.
Electrical diagnosis starts with a visual inspection and continuity checks of each pin back to the harness; follow with a powered test to confirm the presence of expected control voltages while exercising the ice maker cycle, and use a voltage-drop test under load to reveal high-resistance contacts. For mechanical issues, confirm retention force and pin alignment; a connector that rotates or shifts in its receptacle can cause intermittent harvest motor activation or incomplete heater cycles. When compatibility is uncertain, compare the plug pinout and mechanical latch to the refrigerator’s service data before assuming replacement parts are interchangeable.

Compatibility, Replacement Considerations, installation Procedures and Troubleshooting Steps for the Ice Maker Round Plug
the 1129313 Whirlpool Refrigerator Ice Maker Kit Round Plug is a field-replaceable electrical connector used to mate the ice maker assembly to the refrigerator harness. This round plug functions as the primary electrical interface for motor, fill valve, and thermostat/thermistor signals, and replacement requires matching the shell style, pin count and pinout to the original harness rather than relying solely on external appearance. When evaluating compatibility, verify the appliance model number and examine the mating face for keyed orientation, soldered versus crimp contacts, and any shielding or strain-relief features; differences in pin assignment or connector depth can leave the ice maker inoperative or cause component damage if installed incorrectly. For repair planning, obtain the wiring diagram for the refrigerator, confirm the plug’s mating part number, and inspect the old connector for heat damage or corrosion that may indicate upstream faults rather than connector wear alone.
Install the replacement plug with the cabinet power removed and the ice maker in its service position: unclip the old plug, gently back-pull the harness if necessary, then align the keyed shell and seat the new plug until the retention feature engages; re-secure any clips and routing to avoid chafing and to maintain proper strain relief. If the ice maker does not operate after replacement, run targeted troubleshooting: verify continuity of each pin to the ice maker board, check for correct control voltages at the mating pins during a diagnostic cycle, inspect for a failed heater or stuck thermostat, and examine mechanical elements (ejector blades, water inlet valve). Symptoms and focused checks include:
- No power at plug-confirm cabinet mains are disconnected and test for expected control voltages with service manual reference.
- Intermittent operation-inspect for loose pins, bent contacts, or damaged insulation causing intermittent continuity under load.
- Heater or valve failure-measure resistance of heater and valve coil and compare to specification; replace connector if terminals are burnt or deformed.

Q&A
What is the 1129313 Whirlpool Refrigerator Ice Maker Kit (Round Plug)?
The 1129313 ice maker kit is a complete replacement ice maker assembly designed for Whirlpool-family refrigerators that use a round electrical connector. It is indeed a drop‑in style ice maker (motor, mold, thermostat/thermistor and harvest/fill mechanism) intended to replace a failed factory ice maker in compatible models.
How do I verify that this round‑plug kit will fit my refrigerator?
Confirm compatibility by checking your refrigerator’s model number (usually on a sticker inside the fresh food compartment or behind the crisper) and then looking up parts for that model using Whirlpool’s parts site or a trusted parts dealer. You can also visually compare the old ice maker: the 1129313 version plugs into a round (circular) electrical connector/harness rather than the flat multi‑pin connector. If you’re unsure, provide the refrigerator model number to the parts supplier or a technician.
What safety steps and basic procedure should I follow to install the 1129313 ice maker kit?
Before starting: disconnect power to the refrigerator and shut off the water supply. Typical installation steps are: remove the old ice maker (unscrew mounting screws and unplug its harness), mount the new unit in the same location using the factory mounting points, connect the round electrical plug to the new ice maker, reconnect the water supply if a fill tube was removed, restore water and power, and level/secure the unit. Follow the installation instructions packaged with the kit. If you are not pleasant with electrical or plumbing work, hire a qualified technician.
How do I test the ice maker after installation to make sure it’s working?
After restoring power and water, set the freezer to the recommended temperature (see next answer). Many ice makers have either a test button or two accessible test terminals; pressing the button or momentarily shorting the test terminals (with power applied and according to the manufacturer’s instructions) will initiate a harvest cycle.Watch for the ejector arm to rotate and the fill operation (you should here the water valve open and see a small amount of water enter the mold).Do not jump terminals if you are unsure-refer to service documentation or call a technician.
My replacement ice maker powers up but is not making ice – what should I check?
Common causes: freezer temperature is too warm, the ice maker is switched off (some units have an ON/OFF arm or switch), the water supply valve is closed or clogged, the water inlet valve is faulty, the water filter is clogged/restricted, the fill tube is frozen or kinked, or the mounting/leveling is incorrect so the mold doesn’t fill properly. Check that the freezer is cold enough (see below), the water supply is on and has adequate pressure, the filter is within service life, and the harness is fully connected. If those are OK, run the test/diagnostic cycle to observe fill and harvest; replace the inlet valve or ice maker if those steps fail.
What freezer temperature is needed and how much ice should I expect from this kit?
For reliable operation,keep the freezer at or near 0°F (-18°C). Ice makers generally perform poorly above about 5°F (-15°C). Production varies by model and conditions, but a typical residential refrigerator ice maker under good conditions produces roughly 2-5 pounds of ice per 24 hours; initial production might potentially be lower for the first 24 hours after installation as the system stabilizes.
Why is the ice maker overflowing or leaking water after replacement?
Overfilling or leaks can be caused by a malfunctioning water inlet valve (stuck open or overpressured), a misaligned or improperly mounted ice maker (fill cup not positioned correctly), a damaged or clogged fill tube, or a defective shutoff/float mechanism on the ice maker. Verify the unit is mounted squarely and at the correct depth, check the water pressure and inlet valve operation, inspect the fill tube and connections for cracks or leaks, and replace any defective components. Always turn off water and power before inspecting plumbing or replacing parts.
How should I maintain the ice maker and when should I replace the filter or clean components?
Replace the refrigerator water filter per the manufacturer’s schedule (commonly every 6 months or when flow drops), clean the ice bin and surrounding area periodically to prevent odors, and run a cleaning cycle or sanitize the system if ice has a bad taste or smell. If you see mineral buildup on the fill tube or in the mold, defrost and clean per Whirlpool guidance. Regular maintenance and keeping the freezer temperature at the recommended level will maximize reliability and ice quality.
