My appartment does not have cenral AC/heat, it has a GE cooling/heater unit in each room. You can set up low heat or high heat but it continues runing on until you manually stop it when is to hot. Is there a way to set up this units for temperature autocontrol on/off?

answer is in instructions
Save-Smart®
Press () to activate the Save-Smart®Function.
1.Set the thermostat to desired temperature using the +/-
buttons (Note: The default Save-Smart®temperature is 72 ? F)
2.When you reach the temperature at which you want to
set the unit, the set temperature will flash several times
and then the display will return to indicate the current
room temperature and will gradually change as the
room temperature changes.
3.When the air temperature is less than the set temperature,
the heater will run in HIGH heat.
4.Once the thermostat reaches the set temperature the heater
will automatically switch to LOW heat to save energy.
5.When the air temperature reaches 4? above the set temperature,
the heater will turn off. The Heater will cycle off and on in the LOW
mode to maintain the set temperature.
All this happens automatically with Lasko Save-Smart®Technology.
To deactivate the Save-Smart®function, press Save-Smart®
again or (hi/lo) for continuous high/low heat.

AUTOMATIC TEMPERATURE CONTROL(Figure 3)
The automatic temperature function will only operate on "High" heat.
You cannot set the temperature automatically when the unit is in the low heat mode.
1.To set the room at a specific temperature press the () or()buttons
to the desired temperature. The display will now reflect the () and the temperature will be flashing. The Heater is now in Auto Temperature Mode.
2.When you reach the temperature at which you want to set the unit, the set temperature will flash several times and then the display will return to indicate the current room temperature and will gradually change as the room temperature changes. NOTE: the temperature display does not indicate the temperature of the heated air being emitted by the heater.
3.Once the room temperature reaches 2 degrees above the set temperature, the Heater will shut off. Once the room temperature reaches 1 degree below the set temperature, the Heater will turn back on and continue to cycle off and on to maintain the set temperature.
4.This function will cancel if the ()button is pressed. The Heater will now be in High heat and run continuously.
NOTE:It is normal for the Heater "fan" to run for approximately 15 seconds when the Heater shuts off after reaching the set temperature.Press the () and() buttons at the same time to change the display to ° Celsius. Press the same two buttons together again to change the display
back to ° Fahrenheit.

Normal ACs (non inverter) work in the following way

• The AC compressor runs continuously till set temperature is reached in the room
• The compressor then switches off, but the blower fan in the wall mounter unit keeps running. Durint this time the AC fan blows air out at Room temperature (which feels warmer)
• When temperature of room rises then compressor starts running again. During theis period the air coming out from the inner uny is cooled by the condenser coils
• And the process is repeated.... as long as you keep AC running

Ac works this way throught the operation period.
Now if you feel that your AC keeps switching off and on very frequently check the following

• Your AC may be over powered for room *for example a 1.5 ton AC installed in a scenario where 1 ton is enough)
• If there is voltage fluctuation in your area then the compressor may keep shutting don on large voltage swings
  • Solution: Get a Stabilizer
• You have set the temperature setting too high. Max temp suggested for ACs is 25 degree Celsius, any higher will mean the compressor shuts down often. Remember every compressor shutdown and startup draws a high starting current
  • Set AC temperatures between 22 and 24 degrees Celsius
• The thermostat/ Temperature sensor is faulty
  • Get unit inspected by Authorized technician
• There is dust buildup on the outer unit / compressor unit. The dust buildup may cause overheating by preventing efficient heat exchange, This may lead to overheating of compressor and it shuts down to, prevent damage to itself
  • Get unit serviced by Authorized technician
• The fan motor of the outer unit is not working properly
  • Get unit inspected by Authorized technician

Remember to get the AC serviced at least thrice a year to ensure smooth operation

if it is an inverter type air conditioner ( make not indicated) the unit runs continually but the compressor delivery is reduced thereby reducing the load on the motor
as the room warms up again the compressor starts to pump more gas to keep the room at the desired temp setting
older types shut the compressor down and restarted when the high temp was reached

clean blower and coils , check out fan motor and fan capacitor .

The first 3 answers were from idiots. If a person had read her problem they would understand that it is not a oven / stove, but a PTAC unit that heats and cools a room. This type of unit is what is commonly seen in hotels and motels where the individual heating / cooling system is in each room.

Hello, Here is a trouble shooting guide for you and some details of how to fix it based on your symptoms. Here is a link to go to and make sure you jump around the site, it will tell you the fix based on your problem off the trouble shooting table. Link is below , copy and paste in browser. If this helped you, please rate it and some kind words are nice. Thanks Mike

Check temp setting and also room sensor. Setting must be minimum 3 degree more than room temp. Check continuity for sensor. If open replace it. Check coil , air filter and heater element are cleaned.
If high amps, replace heating element. Thanks.

Most little window units are mainly for 300-500 Square foot rooms.
Should be putting around 80-105 degrees top out of those little units, Make sure that your thermostat is set for heat rather then the normal setting of cooling (Turn more towards Heat) also if you have a fan setting you may want to try lowering the fan to low speed vs high fan, which should give you more heat.
Make sure the Filter is clean as well as the coils behind the filter or it will shut down the heaters quicker due to lack of air, shutting down your T-stat and bi-metals quicker.

Good luck!

It sounds like the space is too large for the BTU capacity output of the unit.

Did the unit ever heat the space?

Have you measured the temperature of the incoming air, vs the discharged air?

And finally, based on the Model number in the heading of this thread, this unit is cooling only, no heating (it's not a heat pump).

If it was me I would cnage the sensor first. Simply because it is way cheaper than the control board and these sensors are fickle as hell to begin with.
