The short answer
On an Imperial refrigerator, water inside the cabinet or on the floor is usually humid air condensing past a bad seal rather than a cracked evaporator pan behind the panel. The next thing to rule out is a blocked defrost drain. The top of that list is owner work; only the last cause needs a technician.
What you are looking at
- A puddle appears on the floor at the front — It returns within a day of being mopped.
- There is a sheet of ice on the freezer floor — Melt water froze where it pooled.
- The trim or the door sweats — Water forms on the outside rather than inside.
- NEAR MISS -- water only after the filter was changed — That is a fitting or housing left loose, not a drain fault.
Causes, most likely first on this kind of unit
- The door seal is letting humid air in — A leaking gasket admits warm humid air that condenses on the nearest cold surface. First here, because on an Imperial commercial-grade unit in a working kitchen a small cabinet loses the argument with a leaking seal faster than a large one.
- The defrost drain is blocked or frozen — Melt water from each defrost has one route out. This rank, because a blocked drain puts defrost water exactly where owners find it.
- The cabinet is not level — Drain troughs and pans rely on a level cabinet to carry water to the right place. Placed here: a tilt sends water the wrong way even with a perfectly clear drain.
- The trough or evaporator pan behind the panel — A cracked interior trough, a failed drain heater or a split hose behind the rear panel needs the panel off and the compartment thawed to reach. Bottom of the list, deliberately: it needs a panel off and a meter on a heater circuit, which is why it is last.
Check in this order, and why
- Paper-test the gasket and look for sweat — Water or frost at one corner, with a seal that fails the paper test there, is your answer.
- Look in the trough and at the drain mouth — Ice or sludge at the drain, with water standing in the trough, is the confirmation.
- Only after the accessible drain is proven clear — 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, then find out where it returns first — Dry inside and out, then check both in an hour; where it reappears names the source.
Tools: towelsAbout 15 min
- Clear the defrost drain from inside — Flush the trough with warm water and clear the drain mouth gently; never force a wire through it.
Tools: warm water, turkey basterAbout 20 min
- Paper-test the door seal and level the cabinet — Fix a failing seal stretch and set the feet so the cabinet sits level front to back.
Tools: levelAbout 20 min
- STOP HERE -- the next step needs the rear panel off — Interior troughs, drain heaters and hoses behind the panel are technician work.
Before you open anything
Safety
Unplug the unit or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off.
When to call a technician
The line is simple: anything you can reach without a panel is yours, anything behind a panel or on the sealed system is a technician's.

What this page does not cover
This page covers the Imperial refrigerator 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-trough geometry, heater part numbers, panel-removal order and fitting sizes, all of which differ by family.
