Digital display shows E1 and cabinet is not cooling or cooling erratically

Safety first: Unplug the Danby wine cooler from the wall outlet before removing any panels. Do not work on the unit while it is energized.

• Power reset: Unplug the cooler for 5–10 minutes, then plug it back in to see if the E1 code clears. If it returns, continue.
• Locate the cabinet thermistor: On most Danby wine coolers, the cabinet temperature sensor is a small probe or bullet-style sensor mounted on the rear interior wall or behind an interior panel near the evaporator. Remove interior shelves and the rear liner panel if necessary.
• Inspect the sensor and wiring: Look for broken insulation, pinched wires, or corrosion at the connector where the thermistor plugs into the wiring harness or control board.
• Test the thermistor: With the unit unplugged, disconnect the thermistor from the harness and measure its resistance with a multimeter. Compare the reading to Danby’s service chart (typically around 5–20 kΩ at room temperature). A reading of 0 Ω (short) or infinite (open) indicates a bad sensor.
• Check the harness to the control board: Remove the rear service panel to access the main control PCB. Verify the thermistor harness is fully seated and not damaged or burned at the connector.
• Replace the thermistor if faulty: Order a Danby-compatible cabinet temperature sensor for your exact model. Route the new sensor along the original path, secure it with clips or tape, and reconnect to the harness.
• If the sensor tests good: The fault may be in the control board’s sensor circuit. Inspect the board for burnt components. If no obvious damage is visible, replace the main control PCB.
