Bosch Refrigerator Error Code dR

The dR code on a Bosch refrigerator means the door switch has detected the refrigerator door as open for more than one hour. The control board monitors the door switch signal continuously, and when it registers an open-door state for 60 or more minutes, it displays this alert. The cause can be a door that is actually left open, a defective door switch, or a wiring issue in the switch circuit.

A reset may temporarily clear the dR display, but the code will return if the underlying problem is not resolved. If the door switch is defective or the wiring is damaged, the control board will continue to receive an open-door signal and reactivate the alert. Resetting is only useful after the actual fault, whether an open door or a faulty switch, has been corrected.

If only the door switch needs replacement, parts typically range from $15 to $60 depending on the specific model, and a technician visit to diagnose and replace the switch can add $100 to $250 in labor costs. If the issue is a loose wiring connector, the repair may cost little to nothing beyond the service call. More complex repairs involving the control board or door alignment would increase the overall cost.

Start by confirming the door is fully closed and nothing inside is blocking it from sealing. If the door is closed and the code persists, inspect the door switch for mechanical damage, a stuck plunger, or failed internal contacts by checking for a continuity change when the actuator is pressed. Also check the wiring harness running from the switch to the control board for damage or loose terminals. If the switch does not respond correctly, it will need to be replaced.

Yes, the dR code can indicate a real food safety issue if the door has genuinely been open for over an hour, as refrigerator temperatures may have risen into an unsafe range during that time. If the door was actually open, check the internal temperature and evaluate any perishable foods before consuming them. If the door was closed the entire time and the code is due to a faulty switch, the compartment temperatures are likely unaffected, but the code should still be resolved to restore normal monitoring.
