Whirlpool Inverter Board W11567409 — Restore Compressor Speed & Cooling Efficiency

OEM REPLACEMENT PART Whirlpool Inverter Board W11567409 — Restore Compressor Speed & Cooling Efficiency Part# W11567409 Replaces WPW10629033 Replaces W10629033 Fits Whirlpool Fits Maytag Fits KitchenAid Fits Amana Fits JennAir Refrigerator Not Cooling? Inverter Board W11567409 – Fix Compressor Failure Fast A failed inverter board is one of the most common reasons a Whirlpool-built refrigerator stops cooling entirely. In most Whirlpool, Maytag, KitchenAid, Amana, and JennAir refrigerators with inverter compressors, this board is the first component to fail when the compressor stops running. When it fails, the compressor receives no control signal — the fridge warms up, the freezer thaws, and no amount of thermostat adjustment will restore cooling. ⚡ Common failure point in Whirlpool-platform inverter-compressor refrigerators. Part W11567409 is the genuine OEM replacement that restores full compressor control and brings your refrigerator back to factory cooling performance. ❓ Is This the Right Part? This is the correct fix if ALL of the following are true: ✔ Your refrigerator powers on — lights, display, and fans work normally ✔ The evaporator fan runs but the compressor does not start (or starts briefly then shuts off) ✔ You have confirmed the outlet and power supply are functioning correctly ✔ The ONLY problem is the compressor not running / refrigerator not cooling Not sure? Send us your model number — we'll confirm before you order. 🔧 Common Symptoms Refrigerator not cooling — fresh food and freezer warming up Compressor hums briefly then clicks off (short-cycling) Compressor completely silent — no vibration or heat at the back of the unit Error codes on display: E0, E1, CF, or compressor communication fault Clicking or buzzing from the rear bottom of the refrigerator Fans running normally but no cooling produced ✔ If these symptoms match, the inverter board is the most likely failed component in the system. ✔ In most cases, replacing this inverter board restores normal compressor operation immediately after installation. 📦 Part Details Part Number: W11567409 Type: Inverter Control Board (Compressor Inverter / Variable Speed Drive Board) Replaces: WPW10629033, W10629033, W11175771 Brands: Whirlpool, Maytag, KitchenAid, Amana, JennAir ⚠️ Recommended While Repairing: While the refrigerator is pulled out and the rear panel is off, inspect the compressor start relay and all wire harness connectors at the inverter board. A failed start relay or corroded connector can cause identical symptoms — replacing both at the same time eliminates the most common compressor-side failure points in a single service call. ⚙️ Installation Skill Level: Moderate — 30 to 60 minutes. Disconnect power before servicing. Pull the refrigerator away from the wall and remove the rear lower access panel. Disconnect the wire harness connectors from the old inverter board, unscrew the mounting hardware, swap in the new board, reconnect all harnesses, and restore power. No programming required — the board communicates with the main control board automatically on first power-up. ✓ Compatible Models Confirmed compatible with WRF535SWHZ, WRF555SDFZ, WRF757SDHZ, WRS325SDHZ, WRS571CIHZ, WRB322DMBM, MFI2570FEZ, MFX2676FRZ, KRMF706ESS, KRFC300ESS, KRFF507ESS, ABB2224BRM, JFC2290REP, WRF560SMHZ, WRF540CWHZ, WRS588FIHZ, plus additional Whirlpool-platform models. Contact us to verify your model number before ordering. 💡 Pro Tip Test Before You Replace: Before ordering, unplug the refrigerator for 10 minutes and plug it back in — this resets the inverter board's fault latch. If the compressor starts and runs normally after the reset, the board may have tripped on a transient fault (power surge, voltage spike). If it fails again within 24–48 hours, the board is failing and replacement is confirmed. This 10-minute test can save you an unnecessary part purchase.
