Freezer runs noisy only during defrost or shortly after

Safety first: Unplug the freezer if you plan to access the evaporator area.

Steps:

• Identify noise: Popping or cracking sounds during defrost are often normal.
• Check evaporator mounts: Ensure the evaporator coil is securely fastened and not rubbing against panels.
• Inspect drain pan: Make sure the drain pan is properly seated and not vibrating.
