When I hit the power button, nothing happens. I cannot find my manual, or one on-line. Is there an internal fuse I could check? Thanx

Cause:
Assuming the fuse is good. I believe the cause of this problem is corrosion on the heating element clip leading to the heating element hanging free away from the air-exit radiator. This may lead to water accumulation in places that are undesirable such as under the power board.

Solution:
1. Replace or repair the power board (COR268BV1.0 or COR217BV1.4). See http://www.appliancefactoryparts.com/images/products/2/291480-3.jpg for reference on the COR268BV1.0 traces. I do not know if they are interchangable.

2. Replace the clip. Maybe you can use steel pipe clips from your local hardware store to make one, if you cannot find one online.

Same here. No power. Took it apart and everything looks good. No loose wires or anything unusual.

    Update, I took off the circuit board where the main power comes in. There was some corrosion under the board. Must have gotten water on it somehow?
    Anyway, the PN is COR268BV1.0. It is still under warrenty, so I'll have to see what can be done. One thing is that it does look like a bad design. The soder under the board was very close to its neghbor. Looks like it would be very easy to get a short circuit.

LG LD450EAL no power


Try resetting the GFI breaker, assuming it is connected to one. Also check the main breaker panel to make sure the breaker is not tripped. Unfortunately the electronic panels do go bad in these systems after a few years of service. Try resetting the unit. There should be a tiny reset button on the back. Also if the bucket is full it will not turn on, make sure it is in place and seated properly or it will not turn on. There may be a reset on the cord itself as well, hope this helps.

You may have the humidity extraction level set to HIGH. Try lowering the humidity extraction level to 35% or if you have an analog unit, turn the control knob to maximum. Also cleaning the air intake filter may help.

Hope this helps you to solve the problem and thanks for choosing FixYa.

Nothing comes on, light ,fan, Etc. Is there a reset or fuse to look at? Power to unit is good.


There is no fuse or reset button on your unit.

First, be sure that the water collection bucket is installed properly in the holder. Also, check the top of the bucket for a float valve when you remove it, to reinstall it.

The float valve is in the top of the bucket and may be stuck in the UP position. Therefore, the unit will not start. If you find this (not all units have them), jiggle the float valve arm to get it to return to the DOWN position.

When you reinstall the bucket, be sure that it fits "squarely" into the bucket holder from top to bottom. The bottom of the bucket should not tilt down at all.

NOTE: Before attempting any of the above, turn the unit OFF & Unplug it.

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

Plug the unit in, hit the power switch nothing not even the lights for the buttons.


Check the outlet that the unit is plugged into, to make sure that it has power. The circuit breaker for that outlet may have been tripped. Also make sure that the outlet is not damaged inside or there could be a loose wire connection or a frayed wire to the outlet.

Hope this helped you to start troubleshooting and solving the problem.

Unit does not turn on when the on-off button is pressed. No indicator lights come on. The line cord is good - I have 118 volts across the black and white wires inside the cabinet.


This unit has a 12 amp 125v glass tube fuse on the control board. Chances are you blew this fuse. This can happen if the unit is starved for air and ices up. you must take the front of this unit off to access the fuse of this control board.

There is an internal fuse. Take off the outer plastic casing. The fuse is on the bottom of the board on the upper right of the unit. It's a 12 amp fuse. I had the same problem and found the fuse blown.

Check your tank. Remove it and look to be sure that there isn't any shipping foam or foreign objects in the area which may be keeping the safety switch open. If the area is clear check the switch to make sure that it is not stuck and it moves freely. If that is OK replace the tank and make sure that it is installed completely and correctly. Try it again. If it still does not work I would take it back to the store and have them check it out under the warranty. Good luck.
