Door gasket is torn, hardened, or not sealing, leading to a warm cabinet and condensation.

Safety first: Unplug the unit before replacing the gasket to prevent the fan or light from turning on/off during work.

Steps to check and fix:

• 1. Inspect gasket: Look for visible tears, gaps, or hardened sections.
• 2. Warm and reshape: Minor warping can sometimes be corrected by warming the gasket with a hairdryer and gently reshaping it.
• 3. Replace gasket: If damage is significant, pull the old gasket out of its retaining channel. Press the new Vestfrost-specific gasket into the channel, starting at the corners and working along the sides.
• 4. Check seal: Close the door on a strip of paper at several points. You should feel resistance when pulling the paper out.
