Question about Maytag M7DH65B2A Dehumidifier
Our Maytag M7DH65B2A was working fine one day and the next and forevermore has not been collecting water. When on, the fan runs and I hear a relay click on and the lights dim about every 15 seconds. I've opened up the unit and checked connections and all of the sensors and nothing "looks bad" but after reassembling, it continues the same behavior, of running, seemingly applying the compressor, and yet leaving a bone-dry water bucket. Any advice as to how to narrow the fault to one of the 3 sensors - humidity, heat, and defrost?
This model has a small right-angle drain hole into the bucket that can easily get packed w. mold after a couple of months or years. If you have this problem (especially if water starts dripping onto the floor), take the case apart and clear the tray below the coils. This can fix a number of "not working" type problems.

Sorry to be vague in advance. I am a bit confused as to the compressor seems to be running bit. If the unit is on you should hear the compressor making a continuous noise. What you have described over a relay going click every fifteen secs could be the compressor overload / relay. If it is then the compressor is trying to start hence the dimming lights. Either way I would suggest one of two scenarios either the compressor is faulty or cannot start due to the relay or the unit is short of gas. Eiher way not a good scenario. I would suggest a tech to confirm or spend the money towards a new unit. Hope this helps.
