Bosch Refrigerator Error Code Er dR

Er dR means the refrigerator compartment door switch has detected an open-door condition for longer than one continuous hour. The control board monitors the door switch signal and triggers this code when the open state persists past the 60-minute threshold. It can indicate a door that was physically left open or a door switch that has failed and is incorrectly reporting the door as open.

A power reset, such as unplugging the unit for a few minutes, may temporarily clear the error code from the display. However, if the underlying cause is a failed door switch, damaged wiring, or a door that does not close properly, the code will return once the control board detects the open-door condition again for an hour or more. The root cause must be corrected for the code to stay cleared.

If the fix is simply closing a door that was left ajar or repositioning food items, there is no cost involved. Replacing a faulty door switch typically costs between $20 and $75 for the part, plus labor if a technician is hired, bringing the total repair cost to approximately $100 to $250 depending on your location and service rates. A door gasket replacement is in a similar range, while hinge repairs or control board diagnostics can push costs higher.

Start by opening and closing the refrigerator door deliberately to reset the switch signal. Make sure nothing inside the refrigerator is blocking the door from closing fully, and confirm that the interior light goes out when the door is shut. If the error returns with the door properly closed, inspect the door gasket for damage, check the door hinges for alignment, and test or replace the door switch if it appears faulty.

Yes, this error warrants prompt attention. A door that is genuinely open or a switch that is stuck reporting an open condition means the refrigerator interior is not being properly maintained at safe food storage temperatures. Prolonged warm temperatures inside the refrigerator compartment can allow bacterial growth in perishable foods. The compressor and other components also work harder under these conditions, which can reduce their service life.
