If your refrigerator starts and stops very frequently, you may have an overheated compressor. This refrigerator part is a component in the cooling system of the refrigerator. The reason for an overheated compressor? Take a look in the back of your refrigerator. The refrigerator parts you see clogged with dirt, dust, and grime are the condenser coils. These coils help dissipate heat. Any coating on the coils interferes with that process and can result in a major loss of efficiency of refrigerator parts like the compressor. Clean the coils, and monitor your fridge to see how often it starts and stops once the compressor load is lessened.
