Maytag M7DH65B2A Dehumidifier Questions & Answers
The orange full light is
This problem is usually caused by an improperly installed water collection bucket or the float valve inside the top of the bucket is broken or stuck in the DOWN position.
To troubleshoot this, turn the unit OFF & unplug it. Remove he bucket, check the float valve's position. If it stuck in the UP position, jiggle the handle to make it return to the DOWN position. This will also allow you to determine if the float is broken. If all this checks out, reinstall the bucket "squarely" from top to bottom into the bucket holder. It must make contact with the bucket safety removal switch on the back wall of the holder. When installed properly, the bottom of the bucket will not tilt down at all. Plug the unit in and turn it ON. If everything was done correctly, the unit should start within a few seconds.
Hope this helps you to troubleshoot and solve the problem. Thnanks for choosing FixYa.
Dehumidifier frosting up
It needs gas.
Quite simply the only way it can freeze up is when the refrigerant gas is getting low to the point when it starts super-expanding at the evaporator.
Any authorised refrigeration technician should be able to top it up, and check it for leaks - there may be a seal that is partially shot, or possibly a leaky joint / pipe / compressor. A refrigerant leak detector will track this down quickly.
Only thing is - get a quote for the work first - sometimes refrigerant is pricey enough to make it close to not worth it on some units.
Unfortunately this is not something you are permitted to do yourself (topping the gas up, not the leak checking) due to environmental legislation.
Good luck, it should be worth doing, otherwise it will probably continue to get worse until the compressor fails, maybe quite quickly.
Hope this helps :)
Why does my dehumidifer not work?
If it is not running because it thinks the bucket is full even when it isn't, the problem is that the float is broken or jammed. A replacement is no longer available, but you can find the small switch and tape it so it always stays on. It won't shut off when the bucket is full, but it will run. This assumes all the other panel lights come on properly - you didn't provide much detail about what works and what doesn't work.
Fill light on and beeps but holding tank is empty
If it is like mine, the plastic part attached to the float in the collection bucket is broken and no longer actuates the switch that indicates the collection bucket (holding tank) is full. When I checked several years ago, the replacement part was no longer available. I used tape to keep the switch in the position that allowed the dehumidifier to operate and attached the hose connector to allow the condensate to drain. The collection bucket isn't needed anymore with this arrangement.
The "full light" will not quit blinking.
you take out the filter screen and vacumn it or run it under warm water. As far as the full light is concerned it probably means the last time you emptied it you didn't seat it back into the unit properly. If you take the tank out and reinstall it the light will probably go off. Sometimes I have to do it a couple of times before it seats properly.
