Wherer is the temp sensor?

bad thermostat. the stat can be as must as 5 degrees off. try, if possible testing the unit in a differeent location

SOURCE: air conditioner is frosting up.

Frost is caused by the refrigerant pressure being too low on the low pressure side of the system. That is, the compressor has more ability than the cold coil is using up. This can be caused by insufficient air flow over the cold coil or a shortage of refrigerant.

Insufficient air flow can be caused by a dirty coil, filter, or blower wheel, or collapsed ducts, to name a few. It is most likely that some of the refrigerant has escaped and the leak needs to be repaired and the refrigerant topped up to the right amount. You'll need to use the proper gauges, a good thermometer, and read the chart that is glued inside the access door on the condenser, or...check for any available repairs that are free because of your warranty.

I did know of a Sears 5,000 BTU window air that was simply designed wrong, but that was many many years ago.

personally i'd just replace the thermostat, but try pulling the front panel off and look on the circuit board and see if there is a jumper for F/C or any other settings. you may try changing its position. you can also remove the batteries for 15 minutes and see if it resets itself. the only other thing it could be is a wiring issue.

its telling you the room temp that is been sucked into the evaporator.its normal for this to happen.once you set the temp you want.it stays there untile you change it.but its all good.

SOURCE: unit not blowing cold air

you have a slow leak in your refrigerant and need to find the leak. you will have to get an AC repairman to come to your house and check it for leaks and fix the problem.
