Replaced pressure control switch on well pump, now what's wrong?

We have a 165 foot deep well with a 240 volt pump. About a month ago, we noticed water dripping from it slowly. The pressure read 75 lbs I think my husband turned down the pressure at that point.


Soon after the water pressure in the house dropped off considerable. When you flush, you couldn't completely wash your hands before it ran out. Then leave alone awhile, and it came back. Sometimes when the water went out, you could flush then wait a minute, and it would correct the problem. My husband added more air to the bladder tank. and it worked.


At least until last week . When it got really cold the other night, it happened again, but worse. The pressure gauge was broken, so he replaced it. The points on the switch were burned, so he replaced it today. We went from having slow water to having no water. He says he thinks he got the wires right. One to ground and going left to right red, then 2 yellow wires, then the black. Does that sound right?


Are we missing anything?Replaced pressure control switch on well pump, now what's wrong?
you should only have power going into the pressure switch from your electric panel , normally a black a white and a ground wire . they should go on the terminals marked line . from the pressure switch to a control box you should have another set of wires normally a black a white and a ground wire . these should go to the load or T terminals . Seems to me your pump was building excess pressure and the relief valve is set to release pressure at 75 psi . you should check the nipple going to the pressure switch , remove it and make sure it is clear of rust and sediment build up as this can give the pressure switch a false read, either not reading the correct high pressure ( dripping relief valve ) and not coming on as it falsely reads pressure is satisfied .





Also the bladder tank pressure needs to be set at 2 psi lower than the cut in setting on the pressure switch . check the pressure in the tank when the water is off and tank is completely empty .
