Perlick Refrigerator Error Code DA

DA stands for door alarm on a Perlick refrigerator. It indicates that the door has been left open long enough to trigger an alert from the control system. The unit monitors door status through a door switch, and when that switch reads an open state beyond the threshold, the DA code activates. Closing the door should clear the code and allow the compressor and fans to restart.

If the door has been left open for an extended period, the interior temperature may have risen enough to compromise perishable foods. Check the cabinet temperature before relying on stored items. Once the door is closed and the unit returns to its set temperature, safe storage conditions will be restored. If the alarm has been active for more than two hours, perishable items should be evaluated according to standard food safety guidelines.

If the cause is a damaged door gasket, replacement gasket costs typically range from $30 to $100 or more depending on the model, plus labor if a technician is involved. A faulty door switch is generally a lower-cost component, usually in the $15 to $50 range for the part, with labor adding to the total. If the issue is simply a misaligned door or an obstruction, no parts are needed and the repair cost is minimal.

Start by ensuring the door is fully and firmly closed. If the code clears and the compressor restarts, no further action is needed. If the code persists, inspect the door gasket for damage or compression, check that the door is properly aligned on its hinges, and look for any items inside the unit that may be blocking closure. If all physical checks pass, the door switch itself may need to be tested or replaced.

Simply resetting the unit is unlikely to permanently clear the DA code if the underlying cause is still present. The alarm is triggered by the door switch reading an open state, so a reset without addressing the door condition will typically result in the code returning. The correct resolution is to close the door or correct the issue preventing the door from sealing properly.
