My well is 214 feet deep, and runs at 100 gal/min. During a very hot period, when I had to run the pump, I noticed the cut off switching about every 45 sec. I continued to run the system. I discovered the pump had stopped working and the contactor relay was buzzing. When I try the reset switch nothing happens. Is there a way to test the Contactor relay to see if replacing it would solve it?
