We have a Maytag portable air conditioner that recently has been draining water out of the back of the unit (onto the floor). This occurs when we are running it in A/C mode. We don't run it in fan or dehumidify mode.
We have had this unit for several years now and we did not have to drain the unit except once a month or so. Now, we have to drain it several times a day.
It's almost like the unit is running as a dehumidifier, but it is cooling the room fine and sounds ok.
Please advise. Thanks, in advance.

Re: Excessive water draining from portable A/C
It appears that you have changed the location of the unit, I mean have you relocated to an area whwre the humidity is high, usuallly coastal areas have high humidity.If not is there a door that is being constantly left open causing a lot of fresh high humidity air into the room

there is a holding tank in the bottom of the unit, on the front right by the floor is a rubber cap that plugs this tank. water evaporates from there, if the tank gets too full, the power button will flash red and the unit will not turn on. put pan under, pull plug and drain if this happens. if it doesnt happen, don't worry about exhausting the water as its not a problem.
There should be 2 ports in the back or on the side with screw on caps take those caps off and you should see some rubber stoppers when you remove them all of the water will drain out. From what you are saying there should be alot to drain out so be prepared for it to pour out.
Condensation occurs when warm, humid air is pulled across a cold fins of an air conditioner and blown out the front as cool, dry air.
What is happening with your air conditioner sounds to be normal operation - here's why:
The condensate usually drips onto the ground from traditional window air conditioner units or through a pipe to the ground from remote air handlers of split systems. Since yours has no place to drain away into soil or waste pipe, it is collected in a compartment that must be emptied, just like a dehumidifier. When the compartment is full, the unit shuts off - otherwise the compartment would overflow on the the flooring or carpet. This could be a very expensive repair if hardwood floors were damaged or carpeting were to become moldy. Even more so if the the space under yours were finished - like an apartment building or if you used this on the second floor of your home - and damage to the ceiling below were damaged.
You could operate the device if it were connected by a hose to a drain at or below the bottom of the connection point (a floor drain, shower drain, etc.) or if the unit were placed on a counter top and allowed to drain into a sink or other drain / waste pipe below the the hose connection point. The hose must not get higher than the connection point at the drain plug on the air conditioner to work properly.
I have the same model air conditioner, and had the same symptoms. As you've probably discovered, Fedders is the company that actually built it, and went of business. No one is supporting it any more.
However, you may be in luck. I fixed the problem by simply tipping the unit almost all the way over on its back (leave a little gap) and letting the water drain out of the hose and the filter. After that, it started right up.
Air conditioners remove moisture from the air like a dehumidifier does. With portable units it is captured in a removable container and when full will turn the unit off so it won't overflow onto the floor. There should be option for a hose to attach to the bucket which could be run to a drain so you won't have to keep emptying the bucket. Just remember the a/c unit needs to be higher than the drain.
