Grundig Normal Vacuum Effect / Check Valve Issue

Freezer door difficult to open immediately after closing.

Possible Causes

Normal pressure equalization after door closure, Blocked cabinet pressure equalization vent, Faulty check valve (if equipped)

Note: A temporary difficulty opening the freezer door right after closing is often normal due to pressure changes.

Wait a moment: Allow 30–60 seconds after closing before reopening to let pressure equalize.
Check vents: Ensure cabinet vents are not blocked by food or packaging.
Inspect gasket: Make sure the gasket is not excessively sticky; clean with mild soap if needed.
