My Fedders dehumidifier keeps reading full all the time

My Fedders dehumidifier Model M3DH30B2A keeps reading full all the time. Switch is working when held in manually, the float in the tray seems like its not making contact with the switch. The float does not appear to be damaged.

The unit fills but does not stop when full. It keeps running so water is spilling all over.

More than likely, the float valve in the water collection bucket is stuck in the DOWN position. There for the automatic shut off does recognize that the bucket is full. Remove the bucket and check the float valve in the top of the bucket. If it's stuck in the down position, jiggle the arm to get to return to the UP position. Be sure to turn the unit OFF & unplug it before doing the above.

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

Fedders a7dh45b2a*a-r dehumidifier shuts off before the bucket fills

Actually, it's probably doing what it should. Let me explain: Dehumidifiers run until they have lowered the humidity/moisture level to where you have the humidity extraction level set. At that point, the unit shuts OFF, until senses the humidity level has risen above where you set the level and it turns ON again. That doesn't mean the bucket will always be full when it shuts OFF. It may turn ON & OFF many times before the bucket is full. Watch for the Bucket Full Light to illuminate. That's when the bucket is FULL and needs to be emptied.

Hope this helped you understand how the unit works.

I have a Fedders dehumidifier Model A7DH45B2A REV-A. The nipple on the float broke off. Where can I buy a float? Do you have one? How much is it?

Although Fedders, as you knew it is no longer in business, some parts are still available.

Here is a link, with an explodes view of your model's parts.Locate th epart you need and then enter the part number, to see if it's still available. FYI Maytag Dehumidifier parts are interchangeable with Fedders. Fedders made the units for Maytag.

I hope this helps you find what you need.

The float switch where it pivots wore out i would like to buy a replacement tray if possible

I think what you're looking for is the bucket or tank assembly that has the float valve in it, rather than the tray. In any event, there are not many parts still available for this unit, as it has been discontinued by Fedders. However, they did make the identical unit for Maytag & Whirlpool and you may be able to find interchangeable parts from them.

In the meantime, here is a link to some Fedder's parts that are still available for your model.Which may be helpful in cross referencing the Maytag & Whirlpool models.

Sears Parts Central may be another good source.

Hope this information has helped steer you in the right direction.

Bought a Maytag 65 pint dehumidifier second hand. A hose or tray didn't come with it. Need to buy parts and would like to get a free owners manual. Model # M7DH65B2A*A Thank you, J Duke

You can find the manual and the parts online a Sears Parts Direct. However, when you enter the model number, drop the *A off the number.

FYI - This unit was made for Maytag by Fedders. And they make one of their own, with the same model number.

Hope this helps you.
