Whirlpool Refrigerator Refrigerator Control Board 4388932

Is This the Right Part?

Confirm the complete model number before ordering. Similar parts may use different connectors, dimensions, hose positions, electrical ratings, or mounting points.

• OEM quality, designed for Whirlpool and compatible brands. The 4388932 control board is the adaptive core that manages when and how your defrost cycle runs, calibrated to your appliance’s typical usage and evaporator temperatures.
• Adaptive defrost technology. Rather than a rigid defrost schedule, this kit tunes defrost cycles based on real-world usage, reducing unnecessary defrosts and helping preserve fresh food temperatures.
• Comprehensive kit, ready to install. Includes the control board and the necessary components needed for a straightforward replacement, so you won’t chase missing parts or separate harnesses.
• Pre-programmed and install-ready. The board ships pre-programmed for quick setup, letting you get your fridge back to optimal cooling with minimal downtime.
• Energy efficiency and ice control. By preventing over-defrosting and ensuring proper cycle timing, it helps minimize ice buildup and maintains stable freezer and fridge temperatures.

• Refrigerator won’t defrost or defrosts too slowly, leading to frost and ice accumulation.
• Freezer coils become coated with thick frost or ice, compromising cooling performance.
• Refrigerator runs continuously without cycling off, wasting energy and wearing components.
• Temperature control becomes erratic—food shelves drift between too warm and too cold.
• Defrost cycle fails to activate when needed, causing gradual cooling inefficiencies.

• Versus non-adaptive boards: This kit’s adaptive timing responds to actual usage, which reduces unnecessary defrost cycles and stabilizes temperatures, unlike fixed-timetable replacements.
• Versus generic or non-OEM parts: Genuine OEM components are engineered to fit precisely, minimize compatibility concerns, and preserve your refrigerator’s intended performance and efficiency.
• Versus full control-board replacements: While broader control-board options exist, the ADC-focused kit specifically targets defrost optimization, which is often the most common source of frost and temperature issues in Whirlpool-family fridges.

• Disconnect power to the refrigerator and locate the control board area (often behind the fridge or inside the control panel).
• Unplug the wire harnesses connected to the old board.
• Mount the new 4388932 ADC board and reconnect harnesses, ensuring secure connections.
• Restore power and run a quick defrost test to verify proper operation and cycle timing.

• Decades of Canadian repair expertise. 30+ years serving appliance repair professionals across Canada, with a deep catalog of compatible parts and know-how.
• Specialist guidance when you need it. Expert phone support from appliance parts specialists who understand how the ADC board integrates with Whirlpool-family models.
• Fast shipping to minimize downtime. Prompt dispatch across Canada so homes can restore cooling quickly.
• Guaranteed fit verification. We stand behind compatibility and installation fit, helping you avoid incorrect purchases.

• Double-check your refrigerator’s model number against the kit’s compatibility notes to ensure a seamless replacement.
• After installation, run a controlled defrost cycle and monitor temperatures for 24–48 hours to confirm stable performance.
• Keep the appliance’s power disconnect period brief during replacement to protect electronics and ensure a clean reset.
• Consider pairing this ADC kit with a routine frost monitoring plan (thermometer checks in both fridge and freezer compartments) to catch drift early.
