Refrigerator Compressor Not Starting? Start Device Kit 7006962 – Fix Clicking or Humming Fast

If your refrigerator compressor clicks, hums, and shuts off without starting, the start device kit is the most common — and least expensive — fix. In most BSH-built refrigerators (Thermador, Gaggenau), this is caused by a failed PTC start relay or overload protector. When it fails, the compressor attempts to start, draws excess current, and immediately trips the overload — leaving the refrigerator warm and clicking every few minutes. ⚡ Common failure point in BSH-built bottom-freezer and French door refrigerators. Part 7006962 is the genuine OEM start device kit that restores reliable compressor starting and full cooling performance.

❓ Is This the Right Part?

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

• ✔ The refrigerator powers on — interior lights work and the display is active
• ✔ You can hear a click or hum every few minutes as the compressor tries to start
• ✔ Power supply and outlet voltage are confirmed OK
• ✔ ONLY problem is the compressor not running and the refrigerator not cooling

🔧 Common Symptoms

• Refrigerator not cooling — compressor clicks or hums every few minutes then stops
• Compressor body is hot to the touch but never runs for more than a few seconds
• Refrigerator runs continuously with fans but no cooling
• Rattling sound from the back lower panel near the compressor

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

✔ In most cases, replacing this start device kit restores normal compressor operation immediately.
