The short answer
Start with condensation on the outside rather than a leak: on a Commercial Cool garage chest freezer it accounts for more of these than anything else, and frost that has melted and found no way out is the next thing to rule out. This cabinet usually lives in a garage or a basement, on a circuit shared with other things and in air that is humid in summer and near freezing in winter. Work the list in the order it is given and you will either fix it or know what to tell the technician.
What you observe
- Beads of water over the lid and the sides — The cabinet is sweating into humid room air rather than leaking.
- Water standing in the bottom of the cabinet — Meltwater that could not get out, which on a chest is exactly where it collects.
- NEAR MISS - water with a soft load — Then the cabinet has a temperature fault and the water is the evidence. Read the cooling page for this freezer instead.
Causes, most likely first on this brand
- Condensation on the outside of the cabinet — The likeliest cause on this brand: a cold shell in humid air sweats exactly as a cold glass does, and what beads on the lid and the sides runs down to the floor and reads as a leak.
- Meltwater from frost that has thawed — Next most likely: everything in the cabinet that looks like ice was once humidity in the room, and any interruption - a defrost, a power cut, a lid left open - turns a rind of frost into more water than the cabinet was built to contain.
- The drain plug, open or gone — Third on the list: a chest freezer drains through one plug at the bottom of the cabinet, and a plug left out after a defrost or lost altogether puts every drop straight onto the floor.
Check in this order, and why
- Decide first whether the water is on the cabinet or in it — Sweating and leaking look identical on the floor and have nothing else in common.
- Empty the cabinet and find where the water is collecting — It separates water that melted inside from water arriving from somewhere else.
- Check the drain plug first — On a chest it is the commonest cause, it is on the outside, and it takes ten seconds.
What an owner can safely check
- Note whether the water appears on humid days only — A cabinet that beads in August and stays dry in March is telling you about the room, not about itself.
About 5 min
- Take the load out, dry the bottom of the cabinet and look for ice under it — You cannot judge where water is coming from through a layer of frozen load.
Tools: coolers, towelsAbout 45 min
- Find the drain plug and confirm it is in and seated — It is on the outside at the lowest point of the cabinet, and it is the first thing to check after any defrost.
Tools: torchAbout 10 min
- STOP HERE if the next step means the rear panel or a meter — Behind it are the evaporator and live terminals, and that is where owner checks end.
Before you open anything
Safety
Unplug the freezer before moving it or working behind it, because a capacitor can hold a charge after the power is off and a garage floor is rarely dry. Look at what the cabinet is plugged into as well - water tracking towards an outlet in a garage is a different and more urgent problem than a leak.
When to call a technician
Call when the plug is in, the lid seals and water still collects inside the cabinet on dry days. Do not call for beads of water over the outside of the cabinet in humid weather: that is condensation on a cold surface, and no repair will change it.

What this page does not cover
This page covers garage-standing chest freezers as a class rather than any model. Drain plug positions and gasket profiles differ by family, and where a family- or model-specific page exists for your unit it is linked below and is the more specific answer. Not here: ambient ratings, capacity figures and part identifiers.
