SOURCE: fan does not come on

I've seen abunch of these. The fan motor has a fuse wound into the windings. It cannot be replaced you need a new fan motor. The motors seem to run hot normally, leading to a short lifespan.
 I suggest buying a better brand unit.

SOURCE: DH30 Dehumidifier Compressor Does not Operate

I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.

SOURCE: Blown Fuse on Compressor of Dehumidifier

That part is a thermal protector. If you can't find it at Radio Shack they should be able to direct you to an appropriate electronics store.

SOURCE: compressor does not start

When the compressor tries to start, but only hums and draws a lot of current, the problem is most likely either a bad compressor or a bad run capacitor.

On the Kenmore model 25357510790, the capacitor is a 20 microfarad, 370V oil-filled capacitor, I believe. If you can get one at a reasonable price (around $25-35), it might be worth trying.

If the compressor is bad, the dehumidifier is not economically repairable, if not in warranty. Unless you know someone in the repair business that would do it for you for just the cost of the compressor, that is. ;<)

Other, less likely, problems:

A bad connection (high resistance, say, greater than 2 ohms somewhere in the circuit, including a bad plug or receptacle).

I have a whirlpool dehumidifier (AD75UST0) and it appears to be 'dead'. is there a fuse or a reset?


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).

Have a kenmore dehumidifier 42-54501 - I bought it w/o instruction book. Can you tell me where to get instruction book??? Thank You


Since it's a Kenmore ( a Sears house brand) that was made by Whirlpool. You can download the Owner's Manual at Sears Parts Direct or Sears Parts Central.

Hope this helped you, Joe.

My dehumidifier is not working. The control panel lights-up, but its stuck on 70% humidity and won't adjust down. I took it apart and noticed burnt marks next to the circuit that controls the humidity....


I'd say you're right on target. In which case, although the unit was manufactured my Whirlpool for Sears under their house brand, Kenmore. You can find the part(s) online at Sears Parts Central
http://www.searspartsdirect.com/partsdirect/index.action . If you can do the replacement yourself, you'll really save $$ on labor.

Hope this helped you. Please let me know. Thanks.

Kenmore dehumidifier 54501: Fan does not work. I


Call sears see if the compressor is under warranty

Fan does not operate in my 54501 Kenmore dehumidifier; therefore, unit gets very hot.


Shut the power off to the unit, spin the fan blade to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.

I have a Kenmore 54701 dehumidfier, less than 2 year old. the power is on, a fan seems to be running, I no longer hear a compressor turn and, and no water is collected?


The sealed system of the Kenmore 54701 dehumidifier is warranted (Parts & Labor) by Sears for five (5) years. Since the fan in your unit runs but the compressor doesn't, I suggest that you return it to Sears and request (demand) a new replacement unit under their warranty. I say "demand" because Sears will undoubtedly tell you that the problem is due to some "other" component which is not covered, and will charge you mega-bucks to repair it. Been there - - done that.

FYI, read the (very low) customer reviews of these units on Sears website and you'll see you're not alone in your experience with Sears' inferior quality units.

Above all, do NOT pay to have it repaired. That money is better spent on the purchase of a far more reliable brand of dehumidifier - - (which will most likely cost less that what you paid for the Sears unit).

Yes, the fan motor should come on when you start the unit. 
I just came from my basement where i had the same problem.  My fan was not working- it was noisy at first, then it stopped working.  it seems the motor has some play in it and came out of the electromagnetic housing that should make it spin.  once it was slightly out , it no longer spinned.   I took it apart, and then reassembled it nice and tight.  there is still some play, but it is working great.  If it happens again i may try to get a replacement motor.

Dehumidifier not dehumidifying ...


Save the old one for parts if you get the same new one but I def. don't reccomend buying this unit again. The reviews are bad. The fan is not covered under the warranty except first year or extented warranty. I spoke with Kenmore & Sears about this to see if coverd under 5 yr. Only compressor,tubing & refrigeration system(see inside of front cover for warranty info.)

Sound more like a sensor/circuit board problem to me since fan is turning. I think the signal determins which setting fan needs via sensor assembly to run. I could be wrong. Justa thought.

Can you def. hear the compressor come on. You can look through grill to see fan spin & the compressor makes a clank/clunking noise/ The fan & compressor should turn same time. Good luck! If you got any info. on my fan problem & you have update or fixed your problem I ccould use some help. Check post for my problem.. Thanks! panfan1
