whirlpool window a/c , compressor cycles

I have a whirlpool window a/c unit which is permanently window mounted in my home. I have noticed that on hotter days, (90 degrees) that the compressor cycles off about every 10 minutes, and will stay off for about 5 minutes before coming on again. Upon doing some reading concerning this topic, the condenser fan is running fine, and the speed does not change. During the time the compressor shuts off, I have also tried adjusting temp settings, fan speeds etc. Nothing seems to help. During the evening hours, when the temp drops to 70 degrees, the compressor will run constant. Is there some type of thermal switch that could be causing this? While listening to the unit run, there is no obvious grinding noise that would indicate bad bearings in the fan motor.

Any help is appreciated.

Thanks.

Outdoor coil most likely plugged with dust.

I thoroughly sprayed the outdoor condenser to wash out any and all dirt. The unit seems to be running better now, but I noticed that it still seems to cycle, but the off time now is much shorter. Now the compressor will run for 15-20 mins and will shut off for 2-3 mins. now. Is this normal, or is there still an issue?
