Haier dehumidifier will not power on

Turn the ON/OFF Switch to OFF and unplug the unit for 15 minutes.
Once the time has elapsed, plug the unit in and turn the unit ON.

Hopefully, during that 15 minute timeout, the electronics reset and reverted back to the original factory settings. And the unit will turn ON when you press the ON/OFF Switch.

It's also a good idea to check the outlet it's plugged into. It very well could be an issue with the outlet (no power) or the circuit breaker for that outlet has tripped.

If you continue to have a problem getting it started, contact LG Customer Support 1-800-243-0000.

I have an amana d545m in the crawl space at my lakehome...when i went to check on the furnace filter, i noticed it was not running and has no and what do i check to diagnose the...

First, make sure that there's power to the unit. Has a circuit breaker in the circuit breaker panel been tripped? If so, unplug the unit before resetting the breaker. Also, check the receptacle or extension cord that you're using to power the unit, as it may be damaged.

If you have power to the unit, it may be that some critter or insects have gotten into the unit and shouted it out. In which case, you're lucky that it didn't start a fire. It's not a good idea to leave the dehumidifier running unattended for a week or more.

Hope this helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

First, check the source of the power to the unit, Has a circuit breaker in your home's circuit breaker panel been tripped? If so, unplug the unit, before resetting the circuit breaker. If that's not the case, check the outlet it's plugged into. It may be damaged or have a loose wiring connection. Be sure to turn the circuit breaker for that receptacle OFF, before removing the cover plate.

If all of the above checks out OK, check the water collection bucket, as it may need to be emptied and/or the bucket was not reinstalled properly or the float valve in the top of the bucket is stuck in the UP position, If so, jiggle the arm of the float valve to get to return to the DOWN position.

When reinstalling the bucket, be sure that it fits "squarely" into it's holder and makes firm contact with the bucket safety removal switch.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

Model GHD30 will not run. Have power to the board. I can hear a click noise when turning the switch on. I electricially checked the compressor and fan both ok. PCB board?

Jim, you may also want to check the water bucket installation, too. If it is not properly installed, the unit will not turn ON. Also, check the float valve in the top of the bucket. It may be stuck in the UP position. In which case the unit will not start. Giggle the arm of the float valve to get it to return to the DOWN position.

Hope this helps you to further troubleshoot & solve the problem. Thanks for choosing FixYa.

Just stopped working. When I turn unit on the power light comes on for about 2 seconds then goes off, nothing else happens. Any ideas?

It may simply be that the water collection bucket is not installed properly or the air intake filter is clogged.

Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Remove the air intake filter and clean it, if necessary. While the unit is unplugged and OFF, remove the water collection bucket and reinstall it. Making sure that the bucket fits "squarely" from top to bottom, in the bucket holder. It must make contact with the bucket safety removal switch, to activate the unit. Once you have reinstalled the bucket, make sure the bottom of the bucket is not tilting downward.

If you cleaned the filter, be sure it is totally dry, before reinstalling it. Then plug the unit back in, turn the Master ON/OFF Switch to ON and if everything was done correctly, the unit should start and run. DO NOT OPERATE THE UNIT, WITHOUT THE AIR INTAKE FILTER INSTALLED.

Hope this helped you to troubleshoot and solve the problem.

My DeLonghi DEM10 wont power on any more - like fuse gone

The tank may be full. Your dehumidifier has a safety device that turns off the dehumidifier when the water tank is full. Usually the tank itself either presses against a switch or there's a device connected to the tank that triggers a switch when the tank is in place and full.

If you've emptied the tank and the unit doesn't run, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger.

Bogus 'Full' warning

or you could just tape the bucket in place. when the compressor kicks in the unit vibrates which might be shacking the bucket loose to the point that it doesn't make contact with the switch.
