Bosch Refrigerator Error Code DOOR OPEN

The DOOR OPEN error means that the refrigerator detected one of its doors was not properly closed for longer than the defined time limit. The appliance monitors door position through a door switch circuit connected to the main control board. The error is triggered to alert the user or technician to address the open or improperly latched door before temperature and food safety are affected.

If the door is genuinely open or not sealing properly, warm air is entering the cabinet, which can raise internal temperatures and put food safety at risk. You should address the error promptly. If the error appears to be a false reading from a faulty switch and the door is physically sealing well, the refrigerator may continue to cool, but the underlying switch issue should still be diagnosed and repaired.

Repair costs vary depending on the cause. If only a door gasket needs replacement, parts and labor typically range from $100 to $250. A door switch replacement is generally in the $75 to $200 range for parts and labor combined. Hinge adjustment may cost less if no new parts are required. Diagnostic fees from a qualified technician are usually separate and can range from $60 to $120.

Start by checking that all doors are physically pushed closed and latched. Inspect the door gaskets for damage or gaps that might prevent a proper seal. If the doors appear fully closed but the error persists, a technician can access the Switch submenu in the Bosch Service Menu to confirm whether the door switch is reading correctly. A faulty door switch or misaligned hinge may need to be adjusted or replaced.

A reset may temporarily clear the displayed error, but it will return if the root cause is not resolved. If the door switch is faulty or the door is still not closing properly, the control board will detect the condition again and reactivate the alert. Resolving the physical or electrical cause of the error is required for a permanent fix.
