I recently experienced a Square-D pressure switch that went bad. One of the two separate contacts within it (along with a spring) came loose and fell off inside it. No breakers were tripped. I cut the power and managed to push the contact back on. It cylced a couple of times, but was working loose again and eventually fell off a second time. Again, no breakers were tripped. As a temporary fix to allow us to have water, I pushed the contact back on and put a slight bend on the piece of metal that holds the contact and spring in place, and that seemed to work for several cylces. Eventually, like after several hours, it tripped the main circuit panel for the first time. It tripped once durign a 24 hour period. There were no shorts in the rigged up switch (the slight bend). Resetting the main circuit breaker once allowed us to have water for many hours of use.
The next day I replaced the pressure switch with a new one (30/50). It has functioned for one week now without any problems...until this morning. The 220 main circuit breaker tripped again, but hadn't until last week, the day prior to putting the new switch on. So far, the breaker has not tripped again, but I believe it is just a matter of time. Did the faulty switch cause issues with any other electrical parts or to the pump itself? I reviewed some other posts, and there was mention of a capacitor failure or some relay problem related to another person's similar but different problem.
When I replaced the pressure switch I shut the water valve off that leads from the well to the switch and shut another valve off that leads from the pressure switch to the air tank. I'll check the pressure in the tank when I get home, but I don't believe that the tank is causing an issue. It should be set at whatever it was when I started having this problem.
Any help that you could give would be appreciated. Thank you.
