Wine cooler displays E7 and may not cool or may shut down unexpectedly.

Safety Warning: Unplug the unit before accessing the compressor compartment. The compressor and associated wiring carry line voltage.

Steps:

• Check ventilation: Ensure there is adequate clearance around the wine cooler per Whirlpool installation specs. Blocked vents can cause overheating and overload trips.
• Access rear compartment: Remove the rear lower access panel to expose the compressor, start device, and control board.
• Inspect start relay/PTC: Remove the start device from the compressor terminals. Shake it gently; if it rattles or shows burn marks, it may be defective.
• Test compressor windings: With power disconnected, measure resistance between the three compressor pins. You should see three finite resistance values; any open circuit or direct short to ground indicates a bad compressor.
• Replace start device: If the compressor windings test good, install a new Whirlpool-compatible start relay/PTC and overload protector.
• Check wiring and board: Inspect the compressor harness and the control board relay for signs of overheating or damage.
• Monitor operation: Restore power and observe. If E7 returns and the compressor hums then clicks off, the compressor may be mechanically locked and require sealed system service or replacement.

Important: Sealed system and compressor replacement should be performed only by an EPA-certified refrigeration technician.
