Two catches, and a moving vehicle
A refrigerator door in a vehicle has to survive travel as well as use, so it carries a travel catch as well as a normal one. Most door complaints on these units are about that catch, or about a cabinet that has shifted slightly on its mountings, rather than about the gasket itself.
What you are seeing
- The door swings open in transit.
- The travel catch does not hold.
- Condensation on the door frame.
- The gasket is flattened or holding grit.
- A visible gap at one corner of the door.
- Not this fault: A warm cabinet with a good seal is a cooling fault - read that page.
- Not this fault: Frost inside the freezer section belongs on the ice page.
Most likely causes, in Dometic order
- Travel catch worn or not engaged — Why ranked: First on a vehicle refrigerator. A door that opens in transit spills the contents and can damage the cabinet.
- Cabinet shifted slightly on its mountings after travel — Why ranked: Second: the door then does not meet the frame squarely and no gasket work will correct it.
- Gasket hardened or holding grit — Why ranked: Third. Vehicles are dusty and gaskets are rarely cleaned, and residue holds the seal off the frame.
- Hinge worn from repeated travel loading — Why ranked: Fourth, and it shows as a door out of line rather than one that simply leaks.
- Door adjusted or refitted incorrectly after work — Why ranked: Last, and normally only where the door has been off.
What to check, in order
- Check the travel catch engages and holds firmly. — Because: This is the first cause and it matters most, because a door that opens on the road is a real hazard.
- Look along the closed door for a gap and note which corner. — Because: A one-corner gap is alignment; an all-round gap is the gasket.
- Run a finger round the gasket for grit and hard sections. — Because: Dust and grit collect in vehicles and hold the seal off the frame.
- Check the cabinet fixings are tight and the unit has not shifted. — Because: Travel movement puts the door out of square with the frame.
Checks you can do safely
- Check the travel catch engages and releases properly. — N: 1 — Tools: None — Time: quick
- Wash the gasket and the frame and dry both fully. — N: 2 — Tools: Cloth — Time: moderate
- Look for a gap along each edge of the closed door. — N: 3 — Tools: None — Time: quick
- Check every cabinet mounting fixing is present and tight. — N: 4 — Tools: Spanner — Time: moderate
- Close the door on a paper strip at several points and check it grips. — N: 5 — Tools: Paper strip — Time: quick
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A refrigerator door that opens in transit throws its contents into the cabin - never travel with a travel catch that does not hold. Never wedge or tape a door to hold it shut for a journey. Do not travel with a loose or shifted cabinet. Keep the vent space behind the appliance clear at all times.
When this becomes a service call
The travel catch will not hold the door. A gap remains after cleaning and after the fixings are checked. The cabinet has shifted on its mountings. The gasket is split or has come out of its channel.

What this page does not cover
This page covers Dometic absorption refrigerators - the gas and electric units. It does not cover the DC compressor refrigerators sold under the same name, whose doors and catches differ, and it names no model-specific catch or gasket. Where a family- or model-specific page exists it supersedes this one.
