It is worth checking before anyone opens the sealed system, and it is the first thing we look at on a unit that has drifted warm. ### What decides the figure - OEM gaskets are ordered to the model rather than cut to fit - A built-in door is heavier than a freestanding one and takes longer to set true - Two doors, or a dual-refrigeration cabinet, changes the job - Panelled doors have to come off and go back aligned with the cabinetry ### How to tell it is the gasket Close the door on a sheet of paper and pull: if it slides out easily anywhere along the seal, that section is not sealing.

This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about Sub-Zero door gasket replacement Close the door on a sheet of paper and pull. If it slides out easily anywhere along the seal, that section is not sealing — try it at several points, because gaskets rarely fail all the way round. Those figures are for freestanding units. A built-in door is heavier, usually carries a cabinetry panel, and has to go back aligned with the run it sits in. Routinely. It makes the cabinet run warm, ice up and work its compressor far longer than it should — the same picture as several far more expensive problems, which is why we check it first.
