Zip Tie
Part #WPW10339879
A zip tie, also known as a cable tie or a wire tie, is a fastening device that holds wires or tubing together. If a machine has wires or tubing that are easily shifted, you need to hold them tightly together using a zip tie. It is a flexible, plastic strip that has serrated teeth and a locking mechanism. If the zip tie is damaged, it should be replaced. Freely moving wires may rub against surfaces, causing them to break over time. Zip ties are single-use and may not be reused after they are removed from a machine. To release the locking mechanism, you will need to insert a small flat tool into the head of the zip tie, between the tongue and the serration, and depress the bar. You can then pull the teeth out of the mechanism to loosen the cable tie. This part is produced by the original equipment manufacturer and is sold individually.

The dehumidifier did not turn off automatically when the collection bucket was full (or removed).

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. It took me five minutes to remove the cover (Phillips head screwdriver), 30 seconds to replace the switch, and a few m inutes to re-install the cover. Works like a champ.

bad control on 1998 Whirlpool dehumidifier

Disassemble all the housings starting with front cover, top, sheetmetal side/back piece and top styrofoam support. The top slides back 3/8" before you can lift it up off the keys. Carefully pry/pop the control board loose from the top piece and swap all the wires. Had to cut loose 2 zip-ties to re-route the tank switch wires: immediately replace with new zip-tie left full loose so new wires can be re-routed without wiring bundle falling all over. Get all the wires positioned and finish tightening up the zip-ties, but not all the way, just like the factory did. Cut the tails on the ties.

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.
