Freezer door difficult to open immediately after closing, feels like a vacuum

Safety first: No electrical work is required.

Steps:

• Understand behavior: A temporary vacuum making the door hard to open for a few minutes after closing is often normal as warm air cools and contracts.
• Wait a moment: Allow 1–2 minutes before reopening the door.
• Check gasket: Ensure the gasket is not excessively sticky; clean with mild detergent.
• If the problem is extreme and persistent, the pressure equalization valve (if fitted) may be blocked and should be inspected and replaced by a technician.
