12v rv freezer difficult to open,,,suction

Just tape a 1" piece of small diameter metal tubing to the gasket to break the seal and allow pressure to equalize. That small gap will barely effect the efficiency of the unit.

maybe try a little silicone spray .

As I said I'd not modify I'd live with it. And if you were to drill. most anywhere except the back wall on a RV type... I'd not do it however

Thank you to all for the explanations and suggestions. The gasket has no frost or ice around it and appears to be in good shape with no cracks or loose areas.

I have modified a screwdriver to 90 degrees and can fit it in between the door and the freezer frame to release the gasket pressure. It works fine that way but I'd rather not have to do that.

Where would I drill a small hole to relieve the vacuum pressure? I don't see any factory relief valve. It is a Dometic.

We noticed this on our dometic as well, particularly after opening & closing, then on the second opening... it's difficult!

Close it with a little strip of paper or thin cloth etc. across the seal somewhere. Will prevent a tight seal and no suction.

If there is an equalization valve it could be frozen, damaged or otherwise inoperable.

On the air cools I agree.
Residential frost free have a drain (into the Refrigerator part) and from there to a drip tray outside the cold boxes. That drain allows air to be "Sucked up" into the freezer when you open the door making it easier... RV units.. Well mine did not and I had the entire unit out so I know there was no equalization valve anywhere. But alas that's model specific.

Short of drilling a vent hole... (Small) I'd say live with it. the vacuum seal means the door is less likely to open... without permission.

The air cools and creates a vacuum. Some freezers do have an equalization valve to help prevent this some don't. You might be able to use your finger to lift the door gasket enough to break the seal and relieve the vacuum (as mentioned above a screwdriver would work but you may risk damaging the gasket with it).

That wooshing sound could also be air leakage from the gasket not sealing very well sucking in warm air and then condensing and freezing the gasket to the
freezer making it hard to open. As soon as you open it look for ice or even moisture along the gasket and opening. That might give you an idea of where the gasket is potentially bad.

If there is an equalization valve it could be frozen, damaged or otherwise inoperable.

I have seen that happen in the past. If there is some humidity in the air the vacuum is caused when the temperature drops. The damp air makes a tighter seal. You could us a wide screwdriver to help pry the door open and break the seal vacuum.
