We have a DAB Jet 62 on a pressure switch due to our poor water supply pressure. It recently blew the run capacitor in a spectacular fashion, and having replaced it with a new one, the pump won't start. There is voltage to the pressure switch and the new capacitor, and the motor turns freely by hand. I can't see what else would have been damaged (if anything). There is scant info available for these pumps. Even the manual is less than useless for trouble shooting. Any ideas?
U might've burned the start capacitor also. If u don't see one on the exterior,check inside the end bell (cap) of your motor. Do u hear the motor hum? If not there a likelyness u burned ur motor
SOURCE: IS MY WATER PUMP MOTOR BURNED?
The easiest way to be sure is to meter the cord and see if you have 5-10 ohms across the lines and infinite resistance on each to the ground prong. You are better served to use a high output voltage tester as compared to a small hand-held 9 volt meter for testing grounds. It is likley the motor is shot though and the unit will need to be replaced.
SOURCE: My water pump stops and starts. the contacts on
A lot of these pumps do have automatic thermal switches built into the motor end cap, Double check that its being fed the name plate voltage and that the voltage doesn't drop when the pump is running (which would indicate a loose or bad connection or just undersized wire in the circuit)
SOURCE: why wont my Jet pump shut off?
Is the little pipe that connects to the pressure switch clear?
I suggest you remove it and blow through it to make sure it is clear. If the pressure is getting to the switch, it has to shut off ... your switch should be set around 30/50 (on at 30 - off at 50)

The water and therefore the pressure has to be going somewhere. If you are sure that there are no leaks in the house or outside, then the water is going back into the well. There is a check valve either in the suction line of the pump between the top of the well and the pump or down in the well.
If this check valve fails, it allows water to go the wrong way and back to the well. The result is that you lose pressure.
Secondly, you have to be sure that there are no air leaks between the top of the well and the inlet to the check valve. Leaks in that piping will make repriming difficult.
Write back with more and I'll try to help more.
