How to Fix Bosch Refrigerator Error E04

Error Code: E04 Difficulty: Hard

Problem: Freezer door is open.

How to Fix E04 Error (Step-by-Step)

1. First, ensure there are no items inside the freezer blocking the door from closing completely.
2. Inspect the freezer door gasket for any signs of damage, such as rips or warping, that could prevent a proper seal.
3. Clean the door gasket and the surface it touches on the refrigerator with a mild detergent to remove any dirt or stickiness.
4. Check the alignment of the freezer door. If it appears to be sagging, you may need to adjust the hinges.
5. Locate the door switch, which is usually a small plunger or magnetic switch along the door frame.
6. Press and release the door switch to see if the interior light turns on and off. If it doesn’t, the switch may be faulty and require replacement.
7. If the problem persists after these steps, it may indicate an issue with the door sensor or the main control board, which will require a professional service.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.
