Maytag Dehumidifiers - Recent Questions, Troubleshooting & Support

Contact Maytag to ask.

Check if it was recalled as were many dehumidifiers due to a fire hazard, as it did not appear in lists on the internet, but that is something to be certain about.

FIXYA questions in 2010 suggest that model number was manufactured at least that many years ago.

It may be right. Are you sure you need dehumidification?

Put a free-standing humidity meter near the unit to check.

If you still want to run the dehum, take the humidity sensor out of the line and control the unit with a timer.

I had the same problem and went for the s**t or bust option, worked for me.... The pipe that feeds water into the bucket had become 'silted' (clogged up and causing water to flood the floor) so I shoved a pencil up it and wiggled it about. Has been perfect ever since.

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 :)
