You've got this in a UPS section, but it sounds like it is a CRAC unit - with leak detection and a containment pan - or humidity option? Either way, when you say "water alarm" is it a water under floor alarm, Leak detection alarm or something else? I can't find the part number your provide on Liebert's website.

We use all types of Liebert equipment where I work. Speaking with Liebert tech support people was always easy for us.. no hassles or fees. Have a look here to see which area will help you the best.

To your question, the stat, sensor or cable could be bad. If you disconnect it from the terminals - it may clear.

Good luck!

When I worked Electrical in a Hardware store we were told by Nighthawk and f\First Alert and we told our customers that you want the detectors 4-6 feet off the floor never near a water heater or furnace since this can cause false alarms. The CO will rise, so one on each floor should be enough near a central stair if possible. Other wise make sure at least one is in the bedroom.

I assume you mean water leaking on floor of bottom freezer? There should be a small hole in floor in back to drain defrosted water down to pan under unit. This line might be clogged with food or frozen water. Carefully pour some hot/boiling water down tube to clear. You should see it empty into pan under unit where fan evaporates it.

Possible water entry came from the rear cabrio area membranes under the roof drive units, which will allow for water entry into the cabin and will soak the floor. The alarm CU lives under the seat. Normally when they get wet, they have to be replaced. Sometimes your key remotes will also need to be replaced with the alarm CU. Also make sure that your front plenum drains, near your car battery, are clean of leaves and debris. PS; If water is entering from the rear roof membranes, don't do the rest of the work and NOT replace these, as this fault WILL happen again.

Exactly the same.


The hose that carries the water from the top coil to the evaporator pan is plugged with ice. You need to leave your unit unplugged for a long time so the ice in the drain hose can melt. If you restart it too soon the problem will not be solved.
