Will not power on after the electricity came back on in the house!
The power goes out during storms and when it is restored the unit has to be turned on again by pressing the power button. This time it would not turn back on. It may have been zapped with a power surge. The unit has worked well for several years with the power going off and on without a problem. This time when the power button is pressed, the digital display flickers and goes off. No combination of button pressing results in the machine coming on.
I have replaced the pc board with the power button and the display but it did not fix the problem.
What tests do you suggest? I have a multimeter. I assume that the capacitor is there to start the motor so I did not discharge nor test it. I have not checked the power supply for output. Any suggestions are appreciated.

Re: Will not power on after the electricity came back on...
That capacitor is a run cap for the compressor. Your problem sounds like a faulty connection in the circuit which supplies power to the solid state electronics. The electronics will have a 115 VAC supply from the rest of the machine's circuitry, most likely running to a small transformer. Check for 115VAC when you attempt to start the machine. Trace the circuit until you find the point where the power disappears when the start is pushed. If this does not reveal the problem, replace the board that has the transformer on it. There is a faulty connection somewhere which is opening when power is drawn. It is also possible that the compressor is locked & drawing enough power to disable the rest of the machine. Try it with the compressor disconnected, before replacing anything.

do you have any power or display that might give clue to root cauae but dhe two most likely issues that i would first eliminate are protection of electric circuit when the volatge spikes during a power on grid cycle and master reset or other resetfp. many homes are not well grounded thus putting strain on lower cost power for consumer product. inexpensive surge protectors might be robust enough to use in time for actual date.
the other is a switch located behind plastic horizontal grill. a hard reset via holding start button while power cycling might restore the cpu lockup ot main bord toaster.
if this doesnt help more detail is needed.
other thing concerns a precious pbut i? .his might be only a ailed couis condensor is not sufficient and your product that might be your root cause
I'm assuming the that you determined the unit is getting power, because the lights on the dehumidifier light up, when you turn Master ON/OFF Switch ON.
If that's the case, it may simply be that the humidity level you have it set for is equal to or higher than the humidity level in the house. In which case, lower the humidity level to it's lowest setting to see if the unit turns on then. Also, check the water collection bucket, making sure it's installed properly and is making good contact with the safety trigger.
Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
A dehumidifier is a 'de-tuned' air conditioner. Its job is to remove some of the heat from the air, causing a temperature differential which in turn should make the warm air give up some of its moisture ... just like a AC unit.
To understand the operation, you must accept that you cannot cool anything ... you must remove the heat from it. The heat (energy) must go somewhere ... in the case of a dehumidifier, it goes back into the room. Oh yes, also contributing to the heat is the electric components you are running ... the control boards, the compressor and the fan ... all use power and thus, give off heat.
Should there be heat coming out of the unit? ... yes, if it is running. Don't get mad ... these are things you probably learned in 6th grade science class - relative humidity - heat differential - properties of energy - etc.
The applaince parts companies that I work with do not provide a replacement main board. You can write or call the manufacturer to try to get a replacement main board.
These problems occur because of voltage spikes that occur during power outages and lightening storms. You should consider installing whole house surge protection.
All of your electronic equipment is subject to damage; investing a couple hundred dollars for a good surge protector may save you $1000s of dollars in the future.

No. I went away for a week and set mine up in the tub. Power went out and it was off when I got home. You could buy a UPS ( unterruptable power supply) from the computer area in Walmart and hook it up to it. This would allow it to still run for a while and if the power came back on while it was still under battery power it would run like it was running. You can buy larger UPS units that would keep it running for longer amounts of time. Just an idea.
I believe a dehumidifier is supposed to operate in temps above 60 degrees. Even though your house is warmer than that, the air entering the dehimidifier may be getting into that range due to it being on a basement level etc. This is perfectly normal and is not a malfunction with your humidifier.
Your options are to either place the dehumidifier closer to a heat source in order to keep the air which is entering warmer. (I've even heard of someone placing a light bulb in front the unit during winter to warm the air slightly as it enters). Because the dehumidifier's coils get cold in order for it to collect moisture from the air, if they are freezing, giving the unit a rest for a few hours every few hours may allow the coils to thaw in between and prevent them from reaching freezing temperatures while running. You could use a timer to accomplish this, but you'll want to insure that it's a commercial grade timer in order to handle the electrical draw that the dehumidifier requires.
