Hi,
There are many reasons why a dehumidifier willnot work or collect water.

No. I have had a AD75UST0 WHIRLPOOL Dehumidifier for several years. My unit slowly got less and less efficient, then it "stopped" coming on as if it was not working. Upon disassemble and inspection I found fan was no longer spinning. It tries to start then (actually the condenser coils begin to freeze, but no Fan) then it shuts down within 30 sec or so.

I am going to try a replacement Fan and fan start Capacitor (always replace in pairs).

Hopefully, it's not a problem inside the unit that's causing the circuit breaker to trip. Is there another electrical appliance plugged into the same outlet or on that circuit that is ON and draws 15 amps of power? If so, that's the problem. If that's not the case, turn the circuit breaker OFF and remove the outlet cover, so you can inspect the receptacle and it's wiring. A loose wiring connection or a broken or cracked receptacle could be the issue. If you don't find any damage reassemble the outlet and turn the circuit breaker back ON. Instead of plugging in the dehumidifier, plug in a lamp or something similar and turn it ON. Leave it on for more than 5 minutes to see if the circuit breaker trips again. If it does, you'll know the problem is either with the outlet receptacle or the circuit breaker. If doesn't, plug in the dehumidifier (Make sure the Master ON/OFF Switch on the unit is in the OFF position, before plugging it in. Then turn the Master ON/OFF Switch to ON and set your controls. If the circuit breaker trips again, the problem is in the dehumidifier. You will need to call Whirlpool Customer Care, as it's an internal electrical issue.

In case you have misplaced your Owners Manual, I have included a link to it, that you can download and print for future reference. http://www.kitchenaid.ca/assets/pdfs/literature/Use%20and%20Care%20Guide%20-%201188927.pdf

I hope what information I have provided to you, will help you trouble shoot and solve the problem.

You definitely have an electrical short in the unit and should stop using immediately. Have it checked out by a licensed electrician. It is a very real fire hazzard.

wont run below 65 degrees

Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.

I have AD75USTO. Whirlpool  was running yesterday. Today it sound like its starting but will not boot up fan will not kick on. Does it need resetting or what. Only a year old only used for one summer?
