Refrigerator Not Cooling? Bosch Control Module 12026747 – Fix Compressor or Cooling Failure Fast

If your Bosch refrigerator has stopped cooling, the electronic control module is one of the most common causes. In most BSH-built refrigerators (Bosch, Thermador, Gaggenau), this is caused by a failed control module. When it fails, the refrigerator may stop cooling entirely, the compressor may not run, or the unit may display error codes and cycle erratically. ⚡ Common failure point in BSH-built bottom-freezer and French door refrigerators. Part 12026747 is the genuine OEM replacement that restores full electronic control and normal cooling operation.

❓ 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
• ✔ The evaporator fan runs but the compressor does not start or cycles off immediately
• ✔ Power supply and outlet voltage are confirmed OK
• ✔ ONLY problem is no cooling, compressor not running, or persistent error codes on the display

🔧 Common Symptoms

• Refrigerator not cooling or freezer not freezing despite running
• Compressor does not start or starts and immediately shuts off
• Error codes displayed on the control panel (e.g., E01, E11, or similar BSH fault codes)
• Unit runs continuously but never reaches set temperature

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

✔ In most cases, replacing this control module restores normal compressor cycling and cooling immediately.

Locate the control module (typically mounted at the rear lower panel or behind the kick plate depending on model), disconnect all wire harness connectors noting their positions, remove the mounting screws, and swap in the new module. Reconnect all harnesses, restore power, and allow the unit 24 hours to reach stable temperature before evaluating performance.
