Sounds like a problem with the compressor. Should be covered by warranty is it is defective.

I have had the Whirlpool GOld dehumidifier for 4 years. It was working great. Recently, I noticed that it stopped working. When plugged it, it trips my GFI socket. I have tried various outlets and checked...


Obviously, there is an electrical short within the unit. Should it be repaired? Yes, if you want continue using it. But, is the cost of troubleshooting, finding the necessary part and repairing it worth it? Most of the time, the cost to repair a dehumidifier is about the same, as what a new one would cost. Now, if purchased an extended warranty, when you originally bought the unit 4 years ago, then you're probably covered for the repair.

In the end, the decision is yours to make.

Unit will start and run for 5 seconds, then will blow a circut breaker on 20A. circut. This is a model AD75USTO Serial # QU2660438 AKA Whirlpool gold energy star


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.

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

Dehumifier blows out my electrical switch in my electrical panel.


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.

Blows electric breaker model AD50USS2


Hi,
If you are blowing the breaker then you are pulling way to much current on the startup or you have a short in the unit...
either way you probably will be much better off by replacing the unit with a new one... they do not cost enough that it is worth sinking hundreds of dollars into fixing an old one...

Knocks out house curcuit breaker and stopes running. Use to work fine and did for at least two years now kicks out breaker after running for a while. Have moved it to different circuits and still does it....


You will need to put an amp meter on the compressor wires and monitor the reading till it trips the breaker. If the reading exceeds the name plate spec then chances are the compressor is going bad.If the spec is in watts, take your amp reading and multiply it by 120 volts this will give you the wattage of the compressor. For a second opinion take it to repairshop to see if it is worth repairing.
Good Luck!

Fan runs but copressor will not kick on


The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

Unit trips out circuit after a few minutes (20Amp stand alone circuit)


make sure that the circuit breaker for the electrical plug is not faulty, cause after a long lifetime of high amperage flowing through it, the springs will start to get weak. If this is the case then you need to replace the electrial breaker. Otherwise, make sure that the power system on the system is not pulling too much current, Or that there is not a faulty breaker inside the printer itself, which has become weak.

Compressor won't run


the over-current relay is tripping out the compressor motor to prevent excessive current through motor windings. To prove this theory, open unit, find motor wires, disconnect wires from unit, and apply 120VAC to motor using external circuit-breaker source. Run 2 minutes max. If motor continuously turns, then relay is failing. Find it by tracing wires back to source and finding a small rectangular item. If motor again quits after 2 seconds, then this motor has an internal over-current self-resetting fuse that may be doing its job of preventing an electrical overload from a dead (shorted) motor.
