It won't cool below 90. It's worse than a fan. The air is not cool and I can't find the manual. I think I did not install it correctly. Do I have to put ice in that tray? Because that tray is empty. Even after using it for 3 days. I recently found this tube with water in it. I released it and still nothing. The air coming out is hot not cool or cold.

Sounds like the evap fan is not running. The fan takes cold air from the freezer to cool the refer compartment. If the freezer is cold the compressor is running. Generally the freezer will stay cold since the cooling coils are there but it must have the fan working to get the air up to the refer area. Pull everything out the freezer and take the back panel off to view the coils and fan, etc. It's a simple easy job to change the fan. If you find the coils are a total block of ice then it's another problem... the defrost cycle isn't working. Sooo... see if the fan is running in the freezer compartment first. See http://www.partselect.com/Schematics/Maytag/AA43-57.gif for fan location, item 18 is the fan motor. Let us know what you find out.

There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. 1. The humidity extraction level is set to HIGH. Lower it to 32-35%.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the Unit, before removing to inspect & clean it, if necessary. If washed, allow filter to completely dry before reinstalling. DO NOT operate the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures (Unless, you have a Low Temp Unit). This applies mainly to where the air
temperature at floor level is colder than at shoulder level in basement applications. Raising the unit up off the floor, onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full tank of water, will usually resolve this problem.
I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FuxYa.
A portable air conditioner may not cool for several reasons. Check the filter by removing the unit's grill and clean the filter.
Also check for clogs in the evaporator or condenser coils by light vacuuming. Make sure the evaporator isn't frosted over, but if it is, allow it to defrost and normal operation should resume.
Lastly, ensure the ambient temperature is lower than your AC's set temperature, as this can prevent cooling. However, if all of these steps fail to resolve your problem, the compressor may be malfunctioning, and in this case, the compressor needs to be replaced or repaired.
In summary, if the air won't cool, remove the grill and clean the filter. Clean out any clogs in the evaporator or condenser coils by vacuuming them and scrubbing them lightly with an old toothbrush. And since fan is working, you compressor might be defective.
I hope the above information is clear.
Check and clean the filter if found to be dirty. It is usually behind a decorative panel below the cold air output grates (when the cold air is on the top front).
The filter is behind the large, rectangular, slotted front panel. The evaporator coil is behind the filter. The fan behind the evaporator pulls the room air through the filter and evaporator coil where it is cooled and dehumidified. It is then discharged through the grates on the top of the front.
Direct the airflow from the unit up and away or left / right to prevent the cool air from being drawn in the front of the unit (this is where the thermostat sensor is located). Use the highest fan speed to help force the air away from the intake, too. Inspect the condenser and evaporator coils (condenser is outside and evaporator is directly behind the filter. Clean if dirty or icing over. Be sure to install a filter if none was present. There are products made specifically for cleaning between the fins of the condenser and evaporator coils. Use them only as directed.
If these suggestions do not work, you may have a problem with the thermostat, refrigerant level, condenser or condenser fan.
is the distributor inside the condensing unit on this system? it sounds like it is under charged also check the fan operation on the evap along with the filters and evap not dirty. if all is good i would say low on charge. i never had a restriction in a mini split. check the orifice in the condensing unit
check to see if you have a cabin air filter and if it is dirty have it replaced at a local auto shop.. if that isnt the problem and the freon level is correct then you will have to live with it.. a/c are concidered effiectient if they cool 20* below ambiant tempature.. personally i would say have the freon level/quality checked again
The coil in the conditioned space is called the evaporator.
If the water droplets are forming on the ceiling around the evap, it is due, most likely, to the defrost cycle being too long.
Defrost cycle: compressor stops, evap fans stop, electric heaters in the evap come on to clear any ice/ frost on evap fins/ coil.
The ice/ frost melts and some of it turns into vapor. As it hits the cold ceiling surface, it condensates into water droplets. Defrost cycle could be too long. Usually 4 time aday and no longer than 30 minutes should be enough unless there is high humidity.
There could be another cause.
Normally, after a defrost cycle terminates, the evap fans do not come on, due to a delay control. This prevents circulating warm are due to the heaters. The compressor comes on and cools the evap down to, usually 20 degrees or so, and then the fans come on. What could be happening is, the fans are coming on too early and blowing the water driplet off the evap and onto the back wall of the unit.
A third item, is to be sure that the condensate drain is "P" trapped. The prevents warm, outside air from being drawn in and causing exess frost build up, thus excess water and vapor.
90 psi suction too high possible bad valves or non condensablies in the system (AIR) what is the head pressure and what type of freon r-22 410-A? your unit is never shutting off watch out for that electric bill. and did you take apart the condenser and clean it? Tom
