I am in N Illinois. We have a refrigerator in our garage. It is making
water puddles underneath it, which attracts some undesirable
lifeforms. There is no water line coming to the fridge, so the water
much be condensate from the air, either from refrigerant pipes or the
How would one approach finding out what is wrong? Any good starting
Water almost certainly from the defrost cycle. Normally this is
collected in a catch pan and just evaporates. If there is enough frost
forming to produce enough water to overflow the catch pan then you
likely have a bad door seal or have the freezer over packed preventing
the door from sealing and letting in warm moist air to form the frost.
It's also possible that the catch pan is missing or could have broken so
the water it would normally catch is going directly on the floor.
Given that its marking its territory, its probably an automatic defrost
model. The defrost cycle melts the ice that forms in the freezer
section, and the melted water is directed out a drain tube underneath
the unit. Normally, there's a catch pan that contains the water and the
hot air from the fan blowing over the coils evaporates the water.
Either you are missing the catch pan, or its mis-aligned and the water
is running on the floor.
Others have suggested the condensate pan overflowing or not being there but
are you sure the water is not simply condensing out of the air around the
refrigerator door gasket and running down the body of the refrig to the
floor. If the refrig has some age, there is probably a switch inside the
fresh food section that turns a heating wire on to heat the gasket area of
the refrigerator to prevent condensation during warm, humid days. That may
have been switched off. And if not, I suspect that you would always get
condensation around the door of a refrigerator in a Northern Illinois garage
in the heat and humidy we've been having here. I've been avoiding going
outside until this passes.
