Whirlpool Refrigerator Not Cooling or Compressor Not Running? Inverter Board W11598145 – Fix Compressor & Cooling Failure Fast

A Whirlpool refrigerator that isn’t cooling, has a compressor that won’t start, or runs warm throughout is often caused by a failed inverter board. In most Whirlpool inverter-drive refrigerators, the inverter board controls the variable-speed compressor — regulating its speed and power based on cooling demand. When the inverter board fails, the compressor receives no signal and won’t run, leaving the refrigerator completely unable to cool. ⚡ Common failure point in Whirlpool-built inverter-drive refrigerators. Part W11598145 is a certified pre-owned inverter board that restores compressor operation and full cooling function at a fraction of the OEM price.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator powers on — lights and display are active
• ✔ Evaporator fan runs — you can hear airflow in the freezer section
• ✔ Compressor is confirmed not running — no hum or vibration at the back
• ✔ ONLY problem is no cooling — compressor won’t start or runs briefly then stops

Not sure? Send us your model number — we’ll confirm before you order.

🔧 Common Symptoms

• Refrigerator and freezer both warm — no cooling at all
• Compressor doesn’t start or runs for a few seconds then shuts off
• Clicking sound from the compressor area as it tries to start and fails
• Error codes related to compressor or sealed system on the display
• Evaporator fan runs normally but no cold air is produced
• Refrigerator was cooling intermittently before failing completely

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing the inverter board restores compressor operation and full cooling immediately.
