Ariston Refrigerator Error Code dR

The dR code on an Ariston refrigerator indicates a door switch fault. It activates when the refrigerator door remains open or is detected as continuously open for one hour after the initial opening. The code signals that the control board is not receiving a door-closed confirmation from the door switch. Certain functions tied to door switch detection will be inhibited while the fault is active.

Start by confirming the door is fully closed and no items are blocking it from sealing. If the door is closed and the error persists, check the door gasket for damage and inspect the door switch for mechanical failure by pressing the plunger to see if it moves freely. Also examine the wiring connector at the door switch for loose or corroded terminals. If the switch itself has failed, it will need to be replaced.

If the fix is simply closing the door or adjusting a hinge, there is no parts cost involved. If the door gasket needs replacement, parts typically range from $20 to $60 depending on the model. A faulty door switch is generally an inexpensive component, with parts usually falling in the $10 to $40 range, though labor charges will apply if a technician is needed. Wiring repairs vary depending on the extent of the damage.

Yes, the dR error is self-clearing. The code terminates automatically once the control board detects a proper open-and-close cycle from the door switch, confirming the switch is operating correctly. No manual reset procedure is required. If the error does not clear after closing the door firmly, the switch or its wiring should be inspected.

The dR error can become a practical concern if left unaddressed, because a door that is genuinely open or a stuck-open door switch will cause the compressor to work harder, internal temperatures to rise, and food safety to be compromised over time. The refrigerator inhibits certain functions during this fault to limit the impact. Resolving the underlying cause promptly will protect both food and the appliance.
