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.

First, tunr the unit OFF and unplug it for 10 minutes. Then plug it back in and turn it ON. It will automatically set at 70%. Press the - button and lower the humidity extraction level to 45% in increments of 5%. Once you reach 35% press and the - button one more time. Now the unit is set to run continuously, until the bucket is full and the unit turns OFF automatically or you manually turn the unit OFF.

I hope this helped you and thanks for choosing FixYa..
I beleive there is some confusion about the Timer Mode. It can only be set to turn the unit OFF after a selected time period. For example: It's 6pm you want the unit to turn OFF at 10pm. You press the Timer button on the unit itself, in increments, until it reaches 4 hours. At 10pm the unit will turn OFF. As a safety feature, it does not have the capability to turn the unit ON at a selected time and then OFF again. In the interim, until you get really familiar with all the functions of this model, use the control pad on the unit, rather than the remote control.
I hope this helped you understand what the timer does and how to activate & set it.
Sorry to read about your problem, I hope this helps you out.
Their has to be a model difference issue . I have checked the Manuel and have put a copy of the section, for modes. and their is no heat only mode.
Your unit uses heat anyway, so i really do not know how, heat only would help you. I would say to look at the sticker on your friends model, and see if the numbers are exact.
When the unit is first connected to a power supply, the electronic circuit board will automatically default to the following factory settings; Mode: Dehumidifier Humidity Set Air Value:60% RH Fan Speed: = Low
NOTE: In the event of a power failure or the unit is switched 'Off', the most recent settings are retained and restored once the power is switched "On"/resumed. IMPORTANT NOTE: Depending on the ambient humidity conditions, when power is restored or switched 'On' the dehumidifier may not start automatically under the factory or custom (see page 7) default setting. This is an indica- tion that the ambient RH% level of the surrounding envi- ronment is lower than the current default setting and it may be necessary to select a lower set RH% value. DRY MODE SELECTION: 1. The unit does not have to be switched on (opera- tional) to select/set a program. All programs can be selected with the unit in the "off" position. 2. Press the MODE button until the Dry symbol is shown in the mode area of the display. Note: Each time the MODE button is pressed, the setting will alternate between DRY (dehumidifier) and FAN (only) mode.
3. Press the or cursor buttons to select the desired RH% operating value. To select CONTINUOUS operation,pressthe buttonuntilthesymbol"--" appears in the SET AIR display. During CONTINUOUS mode operation, the humidistat (control) will be by-passed and the compressor will operate non-stop regardless of humidity conditions. FAN SPEED SELECTION:
4. Press the fan symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options. The fan speed you select will appear in the LED display; either a 4 blade fan symbol for 'high fan' or a 3 blade fan symbol for 'low fan' will be shown in the display area.
5. When all settings are complete, press the I/O button to start the selected operation (MODE) and the blue opera- tion light will illuminate.
FAN ONLY MODE SELECTION: 1. Press the MODE button until the fan blade symbol is shown in the mode area of the display. 2. Press the "Fan" symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options. 3. When all settings are complete, press the on/off button to start fan mode operation and the blue operation light will illuminate.

TURN UNIT OFF.. MAKE SURE DEHUMIDIFIER HAS NOT BEEN RUN FOR AT LEAST FIFTEEN MINUTES... TAKE BUCKET OUT... HOLD IN THE BUTTON THAT THE FLOAT IN THE BUCKET PUSHES ON.. THEN TURN ON THE UNIT.. DO NOT LET GO OF THE BUTTON EVEN A LITTLE BIT IF YOU DO YOU WILL HAVE TO WAIT FIFTEEN MINUTES AND TRY AGAIN.. IF UNIT WORKS THEN YOUR FLOAT IN THE BUCKET IS THE PROBLEM...
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.
before you go to fix it, what is the setting it is at? What is the tempurature of the room it is in? If the setting has been satified the unit has done it job and if it is too cold in the room it will not operate properly either.
the control board is a very simple design and it is to signal and switch options like fan speed, power on/off, humidity up/down and sets the on/off run time. Like above the board does collect dust,but the true problem runs deeper.
My unit was stuck in run mode with the fan speed, humidity and run timmer non functioning. the unit worked and the power switch turned it on and off. The display said ON
I removed the front cover (two screws) and slight pressure on the side of the cover to remove it. This exposes the control board. The control board can be removed by removing the 6 screws on the board. the cable can then be removed by pulling out the multi-pin ribbon cable.
I diagnosed that only two of the 5 push button switched were functioning. There was also dust and mold on the board. This board is poorly protected from the moist air entering the unit and the constand moisture causes corrosion on the board, the switched seem to be the weak link.
By using a multi meter I noted that only the power switch and the humidity down button were making contact when pressed. Now it all came together. I could turn it on and off. and if you press the humidity down button to the lowers setting (ON) means run all the time.
I used a elecronic contact cleaner and sprayed it into each of the switches. I wiggled it around and blew it out with canned air. It took a few wiggles and blasts but all switched then made contact. I the board back on and tested all functions and it was like new. The contact cleaner should keep it protected for a while. The non functioning of the switches works both ways. They can stick on also. This would explain most of the other control problems. These switched are common and can be picked up at Radio Shack. On a do-it-yourself bananna scale it was a 2 for me, but I had the tools and the spray. I am not sure what sears gets for the PC control board,but this is the issue and if they were to address this the unit complaints would drop greatly.
