The short answer
Start here -- on an Imperial freezer, water inside the cabinet or on the floor points first at a blocked defrost drain, not at a cracked interior trough. Second, and worth checking in the same hour, is humid air condensing past the seal. Work the order below -- cheap causes first, the one that is not an owner fix last.
What you are looking at
- A puddle appears at one corner on the floor — It returns within a day of being mopped.
- Water runs down the outside of the cabinet — The shell is wet rather than the interior.
- Packages at the bottom are wet or frozen together — Water pooled around them and refroze.
- NEAR MISS -- water only during a hot humid week — That is condensation on cold steel rather than a leak.
Causes, most likely first on this kind of unit
- The defrost drain is blocked or frozen — Melt water has one route out of the cabinet. Ranked first: on an Imperial commercial-grade unit in a working kitchen, a frost-free cabinet makes melt water on every cycle, so its drain is where the water shows up first.
- The seal is letting humid air in — A leaking gasket admits warm humid air that condenses and freezes on the nearest cold surface, then melts and runs. Placed here: condensed room air is water that never came from a pipe.
- The cabinet is not level — Troughs and pans need a level cabinet to carry water where it belongs. Ranked here because a tilt sends water the wrong way even with a clear drain.
- The interior trough, heater or hose behind the panel — A cracked trough, a failed drain heater or a split internal hose needs the panel off and the cabinet thawed to reach. It comes last because it needs a panel off and a meter on a heater circuit, which is why it is last.
Check in this order, and why
- Look at the drain mouth and the trough — Ice or sludge at the drain with water standing behind it is the confirmation.
- Paper-test the seal and look for edge frost — Frost at one stretch of the seal names the leak; the water follows from there.
- Only after the accessible routes are proven — Water returning with a clear drain, a level cabinet and a good seal points behind the panel -- a service call.
What an owner can safely check
- Mop up and find out where it returns first — Dry inside and out, check both an hour later, and let the first wet spot name the source.
Tools: towelsAbout 15 min
- Check the drain plug, hose and pan — Seat the plug, confirm the hose ends in the pan and that the pan is not cracked.

- Paper-test the seal and level the cabinet — Fix the failing stretch and set the feet so it sits level front to back.

- STOP HERE -- the next step needs the panel off — Interior troughs, drain heaters and hoses behind the panel are technician work.
Before you open anything
Safety
Power off at the plug or breaker first, and let a loaded cabinet warm on its own rather than forcing ice off with steel.
When to call a technician
Call once the condenser, the seal, the set point and a full manual defrost have all been ruled out.

What this page does not cover
This page covers the Imperial freezer as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: drain-plug locations, trough geometry, heater part numbers and panel-removal order, all of which differ by family.
