UNIT NOT BLOWING WARM AIR-OR REACHING DESIRED TEMP
My model number is not recognized but the correct one is WSKA-A024JK 000 My problem is the same only about the cool air, if the temp outside gets warmer than about 60 degrees or so it seems the heat is working fine. If the temp outside is colder then set the unit on 70 it continuously runs. Set it at 69 and seems to shut off and on correctly. The air feels warm at first then blows cool. If the unit is set any higher it never reaches that temp and continuously runs. My electric bill went from around 135.00 to 456.00 from one month to the next. Breakers have been changed and the vents all seem to be connected and there are no holes. It is getting really annoying to hear this thing run constantly and not heat as other type units I have had. I do live in an older home with less insulation than a new home but we're working on that as well. Upstairs the heat that blows for that area is warm to hot and really works well. I'm disappointed and really need some advice.

Re: UNIT NOT BLOWING WARM AIR-OR REACHING DESIRED TEMP
I assume this is a heat pump. The outside unit may be icing up. It should have a defrost cycle with electronic control that sometimes fails or sensor associated with the electronic determination of when to defrost may have failed or may not be sensing because its out of position. You can check for a defrost problem. If frost is blocking the outside unit air will not pass through it after the frost builds up and you may be able to see the white frost as well. If all this is true you need to get a service manual and use its procedures to find out why the unit is not defrosting.

it's known as the split. Room air going into the unit should be 10 to 12 degrees cooler coming out. Unit size, area to be cooled, insulation value and local weather are considered. If the split is close to the numbers the unit is doing all it can. If it's low on freon the evaporation coils will freeze and ice over.
It sounds as if warm outside air is being drawn back into the room when the unit is not actively cooling. Portable units depend on room air to carry the heat outside, & therefore will not work properly if the room is too airtight. Provide a makeup air passage by leaving the door slightly open, & see if this helps. Use a room thermometer to see if your desired temperature is being reached. Note that if the wind is strong & coming from the wrong direction, it may not be possible to prevent warm air drawback.
If the unit is frozen you should be able to see ice at the indoor coil. If you pull the air filters and peer inside to the indoor coil there may be ice. Either way it needs service. If no ice and blowing cool not cold it could be the condenser coil is dirty. On the outside you can see the air leaving side of the condenser coil. The air entering side is the side that gets dirty and can only be seen by pulling the unit out of the wall. Its best to leave it in the wall and call a tech that has experience with ptacs.
Hey kellyrepp -- Three things to check quickly, so many things can be wrong, but i will try to help with the info you gave me.
The first sounds like your electric aux heat is not wired in or not working correctly , this should kick in when the heat pump cannot keep up with desired set temperature. For sure thats a problem
The second thing i would check is that the compressor for that unit is running. It should sound exactly like the one for the upstairs, the fan noise should be like a whrrrr , and the compressor should be a semi loud hummm.
Third feel the pipes on the outside unit that are on the outside of the unit (the unit for the second floor) Let the unit run for 5 minuites. Now check that the first floor unit pipes are the same tempereture. They are about 110 degrees or so, depending on the outside temperatur , be carefull not to burn yourself. If the lower unit is colder , the two most prominent problems would be #1 the compressor is not running #2 Low on freon.
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye
