If your refrigerator is short cycling, it can be caused by a number of issues including: An incorrectly set thermostat inside your refrigerator. Dirt and dust on the coils that prevents efficient operation. Faulty capacitors or relays that prevent the compressor from staying on.

The compressor will cycle on and off. As long as the unit is cooling properly it's ok. If it is not cooling enough and cycling it might be low on freon.

thermostat

i think that what you call the defrost is just the compressor not running so it warms . a defrost cycle does turn the heaters on for about 28 min and then goes baci into cold cycle . so if compressor is not running enough look for bad relay on compressor or bad control board that keep thins in ck .. mm

This is most likely the cycling of the AC unit. As the compressor pressurizes the 134a Freon you get the cold air, once it reaches a certain pressure it cuts out. If you are low on Freon it will cycle out more often. Check your freon level with a gauge to see if your within the proper tolerance. If the compressor runs for a period and doesn't reach the right pressure it will cut out to keep from damaging your compressor so it is important to keep the correct amount of freon in the system.

I believe you have a faulty pressure switch. The black hose reports to the switch what the pressure is and either starts or stops the compressor through the switch. Air is bleeding out of the hose ...causing short cycling ... for some reason. Fix the leak - fix your problem

replace your compressor relay. that's what goes wrong 99% of the time

Freezer defrosted everything fan continues to run but will not freeze. Compressor is cycling enough to keep refigerator section cold. 106 Series Kenmore. Turned up thermostat to keep fridge cold and a shorter intermittent compressor cycle run

replace the compressor "compressor relay and the compressor overload" that are on the side of the compressor.
location: should be in the back on the bottom behind the panel.
if you have a circuit board they may need to be replaced as well.

If the compressor is run off of a relay then you could install a delay timer to prevent short cycling.
