AD50USR1 Whirlpool Dehumidifier - Overview

The microswitch that senses a full or missing collection bucket can almost be removed without taking off the cover of the dehumidifier, but the arrangement and orientation of connector contacts makes that very difficult.

While all the housings were off I vacuumed off the parts and coils and washed the fan blades off with soapy water and a sponge. Looked for chafed wires and such. Trimmed the coil case up with sheet metal shears where it was rubbing on the styrofoam bottom tray and gently filed the cut smooth.

Reassembly: snap the board back into the top piece, put the styrofoam top support on, then the side/back metal, then the top, dropping it onto the keys and sliding it forward again. The front piece goes on last.
