Wine cooler displays E5 and interior temperature drifts, unit may short-cycle

Safety: Unplug the unit before working near the compressor or condenser. Components may be hot; allow time to cool.

• Access rear compartment: Pull the wine cooler away from the wall and remove the rear lower access panel to expose the compressor and condenser coil.
• Locate the discharge/condenser sensor: Look for a small sensor clipped to the compressor discharge line or attached to the condenser tubing.
• Inspect wiring: Check for melted insulation, pinched wires, or loose connectors caused by vibration or heat.
• Test the sensor: Disconnect the thermistor and measure resistance at room temperature. Compare to Amana specs. Replace if readings are open, shorted, or unstable when gently flexed.
• Replace sensor if defective: Unclip the old sensor, install the new one in the same location, and secure wiring away from hot surfaces and the condenser fan blade.
• Check board connection: Ensure the sensor harness is firmly connected to the main control board and that there are no burnt traces or discoloration.
• Restore power and monitor: Reinstall the rear panel, plug in the unit, and observe operation. If E5 returns with a known-good sensor, the main control board may require replacement.
