Danby Freezer Error Codes — Complete List

Danby upright and chest freezers show E1/E2/E3/C0/dr/H1 from their DUF-series manuals: temperature, defrost, communication, door-alar, and heater alarm codes. The honest first step across the board is the 5-minute unplug-and-retry Danby itself documents; anything that repeats is a technician job.

• E1 E1 is Danby's temperature-sensor fault on upright/freezer models — the control can't trust cabinet temperature.
• E2 E2 flags a defrosting (evaporator) sensor failure.
• C0 C0 indicates the freezer's control boards aren't communicating — a board-level fault.
• dr dr means the door isn't fully closed — usually the door seal or latch needs attention.
