Question about Maytag M7DH45B2A Dehumidifier

2 Answers

Dehumidifier My Maytag dehumidifier stopped working recently. When I took it apart, I noticed a solid block of ice in the front around the condensing coils. I thought there was a sensor that was supposed to prevent freezing like this. I've had the unit for over 3 years with no problem. Is this a sign that it needs new refrigerant - similar to when an AC compressor runs low. Or perhaps the sensor needs to be replaced?

    I have the same problem. I have seen the sensor all rusted and not fixed. I'll fixe it with a tyrap and let you know if it works again

    My unit also would only produce a block of ice. I took it to the authorized repair agent over a year ago and paid him $40 to look into the problem which would be returned if it indeed was a problem covered by warranty. After a few months they got back to me and told me they could not get parts and that since Fedders was bankrupt there was no warranty anymore. What really frosts me is that they would not give me my $40 back telling me that I needed to get it back from Maytag - fat chance! Maytag just said, "Tough buddy, it's Fedders problem and they're bankrupt!" No more Maytag anything for me. hof

I do believe you have it right. either you are low on freon 22 or the coil sensor and clip has failed so it can not shut off for cold conditions. the sensor can be tie wrapped back on if it is that, the plactic should not fail

Condensation on frigidaire dehumidifier turn to ice


Good Morning Friend,

I understand that the condensation is turning to ice on your Frigidaire dehumidifier, model# LAD704TDL. This can be a possible cause of your dehumidifier being turned on recently. This is normal, due to refrigerant rushing through the coil. Frost will usually disappear within 60 minutes. Another possibility is the room temperature is too low. All dehumidifiers will operate satisfactorily at temperatures greater than 41 degrees Fahrenheit. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your dehumidifier status has changed successfully. Hope this is helpful.

-Best Regards-
WP

Moisture collecting at the top front when running, even at mid power, over the control panel, sometimes turns to ice. if I shut it off when it is doing this the problem stops for awhile


Well, sounds like you have a good cold section in the dehumidifier-- that is good!-- But I agree-- we don't want water condensing on the surface-- and we surely don't need it turning to ice!
A couple questions to help us get to the next level of trouble shooting this problem:
1.) How cold is the room you are running the dehumidifier in?
(Obviously-- the warmer a room is, the easier to remove moisture--
the colder the room, the easier to drop the air temperature well below the freezing point-- making ice.)

2.) Have the air filters been cleaned/changed recently?
A dehumidifier needs a steady fast moving supply of air across its whole condenser/evaporator surface, in order to remove the maximum amount of water from the air, and not freeze up. (I would winder if something isn't blocking the flow of air toward the top of the coil?-- so that the coil in that area is going well below freezing temperatures, and thus allowing water (or ICE!) to develop near the top of the coil?-- Can you check air flow for us?

3.) You have suggested a good solution,-- especially if the above problems can not be easily corrected: Turn off the unit every few hours, and allow the warmth of the room, to defrost the coil....
In fact-- just to make sure that the air flow is not being restricted by ice deep within the coil-- let it stay off over night-- or bring the dehumidifier into a much warmer room, to make sure no ice is still blocking air flow deep within the coil..

Let us know what you learn about air flow, and get back with us-- THen maybe we need to take the trouble shooting deeper insicde the device.

I hope this helps-- MB

Error Code CH 01


I have a Comfortaire BHD501 dehumidifier. A couple weeks ago I noticed ice building up on top of the unit,so I unplugged it to defrost. I plugged it back in and it worked until I noticed the "CH" "01" code. It would run a few seconds then shut off with that code showing. I took off the front of the unit and noticed rust on some of the metal parts. Then I took the cover off the circuit board for the front read out. I noticed corrosion on some of the solder points. When I looked closer at the plastic cover for the circuit board I noticed a small burn mark. The water from the melting ice must have run behind the cover and shorted out the circuitboard. At this point I don't know if new boards are available.

Dehumidifier freezes up


Most dehumidifiers need warmer air to work properly. The temperature in a basement is usually 60 - 65F; too cool for standard models. You could buy a "basement" dehumidifier. They're designed to work at lower temperatures; some as low as 40 F. Costs are about the same as a standard dehumidifier; you just have to find it.

For a cheap fix, try this; it seems to be working for me.

Since the condensate coil (the one icing up) is cold, the air entering it is too cool and the condensate frosts up the coil. Additional condensate freezes to the frost and before you know it, you've got a block of ice. Since the air coming out of the front is very warm take a large piece of cardboard around 6' x 3') and form a V. Placed it in front of the dehumidifier so it channels some of the warm air back to the rear where it warms the moist air up before it hits the cooling fins. It's helped keep the ice down.

If you want something attractive, any screen that redirects some of the air back to the rear will work. Just leave the top open so it doesn't get too hot and the some of the drier air gets out into the room.

Dehumidifier


if the fins feel cold then you should be collecting condensate. so try this: remove the outer shell to access the fins. with a garden hose, spray the fins off thoroughly. you may see a lot of dust and line that was clogging the air flow.
