Possible Causes
Normal cooling contraction, Blocked pressure equalization port, Gasket sealing too tightly
How to Fix / Troubleshooting
Safety: No electrical work is required. This is usually a normal condition.
Steps to manage door vacuum:
- Wait briefly: After closing the door, wait 30–60 seconds before reopening. The pressure will usually equalize.
- Check vent/port: Some models have a small pressure equalization port or valve. Ensure it is not blocked by packaging or ice.
- Inspect gasket: A very tight new gasket can increase vacuum. This typically eases with use.
Note: A temporary vacuum is normal and not a fault unless the door cannot be opened at all or the gasket is deformed.
