In short
A freezer seal that leaks does not usually produce a warm cabinet. It produces frost: humid room air entering, condensing and building on every cold surface until the airflow or the capacity is gone. Appliances at this end of the market are generously made and electronically supervised, which means the cheap causes present exactly like the expensive ones. Do these in order and you will either fix it or hand a technician a much shorter problem.
What you actually see
- The door has to be pulled hard to open again soon after closing — Normal pressure equalisation, unless it is accompanied by frost, in which case air is being exchanged.
- Ice on the outer face of the door or lid — Air escaping and condensing on the outside, which is a clear seal failure.
- A gasket that is stiff, flattened or shiny along one edge — Compression set from age rather than damage.
- NEAR MISS: light frost that appears after heavy loading — Normal humidity from warm food being frozen and not a seal fault.
The causes in order of likelihood
- Door or lid out of alignment — First, and first for a reason. It leads on a cabinet of this class because the door is heavy and its closing arc is precise, so a small loss of level opens the seal along its whole length. The commonest cause. The seal cannot contact the frame evenly because the closure itself has moved.
- Frost build under the gasket — Second. Ice on the sealing face holds the seal open a fraction and then grows, which makes the fault accelerate.
- Gasket compression set with age — Third. The rubber stops springing back against the frame, usually starting at the hinge side.
- Residue in the gasket channel — Fourth. Sticky soil holds the seal open and tears it when the door is forced.
- Body: The order below is what makes this page worth reading. It is a ranking rather than a measurement, and it carries no numbers because no fact bundle supports any.
The diagnostic order
- Look for frost and follow it to its source — Frost marks the leak, and its position identifies the cause.
- Run the paper test at several points around the closure — A sheet pulling out freely at one corner is a located leak.
- Check nothing is fouling the closure — Baskets standing proud and packages at the rim are the usual offenders.
- Body: The order below checks what closes the cabinet before it examines what seals it.
What you can do now
- Defrost any ice from the sealing faces — Ice under a gasket makes the leak worse every day it is left.
Tools: cloth
- Wash the gasket and channel with warm water — Residue and sugar shorten gasket life and hold seals open.
Tools: cloth
- Level the cabinet with a very slight backward lean — A closure that falls shut on its own is one that seals.
Tools: spirit level, adjustable spanner
- STOP before adjusting a hinge or removing a heavy door — These doors carry real weight and the hinges release it in a specific order.
Safety first
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 chest lid and an upright door are both heavy enough to injure, so never take the weight of one alone, and never force a frozen door, which is how gaskets tear.
When this becomes a service call
Call when the paper test still fails after cleaning, defrosting and levelling, when the gasket is split, or when frost returns at the same point within weeks. Both a hinge adjustment and a gasket replacement are routine, and both are cheaper than the capacity a leaking closure costs. If the fault is intermittent, write down when it happens before you call.

This page is written for the appliance class rather than for one Brigade family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
