Door gasket is torn, cracked, or not sealing, causing warm air ingress.

Safety first: Unplug the cooler if you will remove the door for easier gasket replacement.

Steps to replace gasket:

• Inspect gasket: Look for visible tears, gaps, or hardened sections.
• Remove old gasket: Most Hoover wine cooler gaskets are push-in types. Gently pull the gasket out of the door channel starting at a corner.
• Clean channel: Wipe the gasket channel with a damp cloth and dry thoroughly.
• Install new gasket: Press the new Hoover-compatible door gasket into the channel, starting at the corners and working along the sides. Ensure it is fully seated.
• Shape and test: Close the door and check for uniform contact. Warm stubborn areas with a hairdryer to help the gasket conform.
