Window Air-Conditioner runs non stop and never turns off?

This is normal on some models when fan is set to run constantly.
If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.
First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."
Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.
If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:
AREA TO BE COOLED / CAPACITY (BTU/HR)
100 to 150 square feet = 5,000
150 to 250 square feet = 6,000
250 to 300 square feet = 7,000
300 to 350 square feet = 8,000
350 to 400 square feet = 9,000
400 to 450 square feet = 10,000
450 to 550 square feet = 12,000
550 to 700 square feet = 14,000
700 to 1000 square feet = 18,000
If the room is heavily shaded, reduce needed capacity by 10%
If the room receives a lot of direct sun, increase needed capacity by 10%
Add 600 Btu/Hr for each person in the room if there are more than two people
If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.
If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.
