When a compressor stops starting reliably, you can't replace a part like a start relay and move on; you have to investigate why the compressor stopped starting to determine if the bad start relay was a cause or an effect of another cause. For example, if the compressor fan is not running at rated speed, this will make the compressor run at a higher temperature and pressure and draw more current when it starts, thus drawing more start current and shortening the life of the start relay. See this instruction for more on that ==> http://appliantology...nser-fan-motor/
Another cause of a compressor not starting reliably is compromised insulation on the motor windings inside the compressor. This can be easily checked using an inexpensive instrument called a Megger, short for megaohmeter. This video explains...
