Wine cooler displays E1 and interior temperature is much warmer than the set temperature

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

• Power reset: Unplug the cooler for 5 minutes, then plug it back in to see if the E1 code clears. If it returns, continue.
• Access the cabinet thermistor: Inside the Amana wine cooler, locate the small sensor probe on the rear or side wall (often behind a small plastic cover). Remove any shelves blocking access and gently pry off the cover.
• Inspect the sensor and wiring: Check for broken, pinched, or chewed wires, and ensure the sensor is firmly connected to its harness. Reseat the connector if accessible.
• Test the thermistor (if you have a multimeter): Disconnect the thermistor from the harness and measure resistance at room temperature. Compare to Amana service specs (commonly 5–10 kΩ at ~77°F/25°C). A reading of 0 Ω (short) or infinite (open) indicates a bad sensor.
• Replace the thermistor if defective: Remove the old sensor by gently pulling it out of its well or clip. Install the new cabinet thermistor in the same position, route the wiring along the original path, and secure it away from moving parts or sharp edges.
• Check the control board connection: With power still disconnected, access the rear control compartment, locate the thermistor connector on the main control board, and ensure it is fully seated and not corroded or burnt.
• Restore power and test: Plug the unit back in, set a temperature, and monitor for 20–30 minutes. If E1 persists with a known-good sensor and wiring, the main control board is likely faulty and should be replaced by a qualified technician.
