Air Condioner compressor runs continuously

I have a Kenmore Room Air Conditioner, Model# 580.75121501, 1 1/2
years old. The unit puts out very cold air but the temp controller never
cycles the compressor. I have set the temp control has high as 85
degrees and the room temp is cooled down to 75 and the compressor
continues to run, in both the Cool & Energy Saver modes. In Fan mode
the compressor does not run.

SOURCE: dehumidify mode also cools

Some units do cool/dehumidify only im afraid why cant you let the unit dump its hot air into the room then it wont heat or cool the room?

More than likely you is gonna have to replace the control.Sometimes getting a wash rag real hot and going over the buttons will help unstick them.

SOURCE: This goldstar air conditioner model is WG2405RY7

Doe's the temp reach the set point? If not then it will run until it doe's. If you set the stat warmer and the fan keeps running after compressor shuts off check to make sure it is in power saver mode. Most AC units keep more even temp when fan is left on.

SOURCE: Air conditioner constantly running, not cooling house

Ours was worse than yours. It was not frozen up, but it did need freon. The tech told us that the compressor coil (the unit in the attic) was leaking freon and that the unit would have to be replaced within a year, but adding freon dropped the temperature inside from the mid-80s to the mid-70s (on 100 degree days). It might go lower, but we don't set the thermostats below 76. We paid $80 for the service call plus another $197 for 3 lbs of freon (for our 4-ton unit). Total cost: $274. The quote to replace the system with a new 14 SEER unit is $7,000 -- but this will get us through the summer. Oh, be sure to replace your filters monthly and keep your condensor fins clean. Spray them down with a hose (even while the unit is running), make sure there are no leaves or other trash blocking them, and make sure you have 2 feet of clearance around the condensor. Putting plants or other objects right up against it will impede its operation. Good luck!

SOURCE: air conditioner doesn't blow cold air. Continues

If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs

Isn't blowing cold air, clened coils, removed, dirt, leaves, but still no cold air. Seems to be low on Freon. How do I get the unit charged?


The compressor needs to run, does it run? If it runs and the outdoor radiator is not producing heat, then it may be low on refrigerant. The compressor refrigerant lines, the skinny gets hot and the thick line gets cold under normal operation.
To recharge the unit, it needs to be leak checked and repair any leaks found, then recharged. The refrigerant type used needs to be known, a manifold gage set is used to diagnose and recharge.
If you have a window unit, you should have it serviced or replaced.

Download this illustration and then using a good multimeter start basic troubleshooting.


All residential window air conditioners have a cooling system made up of four primary components, a compressor, an evaporator fan, a control or switch, capacitor.When the thermostat is calling for a colder room temperature the compressor is energized. It is normally very quiet. The evaporator is always located on the front of the air conditioner. It also has silver fins. Be sure it is clean. Use a foaming type cleaner and rinse with plain water. Because the evaporator is absorbing heat, it is very cold to the touch. The temperature drop causes any humidity in the air to collect on the evaporator - sometimes called sweat. There is a fan inside the air conditioner that circulates the air for the evaporator and condenser coils. The circulating fan and compressor are running simultaneously. The fan motor has two fan blades attached to it on either end. The fan blade on the inside part of the unit continually draws room air over the evaporator coils, which are cold. The fan blade on the outside part of the unit continually draws fresh outside air over the condenser coils, which are warm. Because the evaporator coils are cold, they cause moisture in the room to collect on them, much like a cup of ice water on a warm, humid day. When the amount of moisture increases, it begins to drip down off of the coils into the bottom pan of the air conditioner.
If the compressor fails to start or the fan you may need to replace the capacitor.
You may need a hard start kit.

Thermostat control The thermostat on a window air conditioner works by sensing the air temperature entering the air conditioner. As the air entering the unit reaches the set temperature it will cause the compressor to turn off. The blower may continue to run depending on the selection chosen on the control panel. Digital thermostats work on a similar principle but display a more precise temperature.
Test for continuity with the multimeter between the two terminals . Warm you should read continuity (contacts closed). If not change it.
Selector switches The air conditioner selector switches allow the user to choose the fan speed. The compressor always runs at the same speed regardless of the settings. If low cool is chosen, for example, the fan runs at a slower speed but the compressor still offers the same cooling capacity. There are other switches to control louver operation and other features on some units.

Samsung window unit air conditioner model # AW2402M freezes up one time, and the next time freezes you out of the room. What is wrong with it, Termistat or compressor?


Try to set the thermostat to higher temperature and monitor if the compressor will turn " off " when the room temp. is cool, and turn " on " when the room temp. is high. If does not work then your thermostat is defective. Continue running of compressor with very cold room temp. can build up ice in the unit. The compressora73b784.jpg should shutdown when setting temp. will attain.

Thermostat ?


The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .
