I hear the motor start, it only stays on a few seconds, then it does the same thing over and over?

Question

the motor won't stay on long enough to pump water, I hear the motor come on it will only stay on a few seconds then kicks off, it will do this about every 15 to 20 min.

Answer 1

the circulator pump is bad. The water is heating up then the thermostat tells the furnace to shut off.

Answer 2

Actually, your problem is that the system is waterlogged. The resevoir tank has completely filled with water, and water CANNOT be compressed. When you open the spigot, faucet, tap, whatever you want to call it, the pressure inside the tank drops immediately to the point where the pressure switch tells the motor to kick in. Within seconds of kicking on, the motor has built enough pressure back into the tank so that the switch tells it to shut off again. Sometimes if the tank is completely full, the motor will kick on an off continuously till you shut it off.
Air and water, if they meet, will eventually mix. Consequently, if you have the old style tank with no bladder, then the water is pushed out of the tank, when you open a tap, by the compressed air above it. Eventually, as I said, the air and water will mix from being exposed to each other and the volume of air becomes smaller and smaller, until it litterally doesn't have enough room to compress at all. In the new bladder tanks, there is a rubber membrane stretched across the center of the tank to keep the water and the air separated so that they don't mix. However, the bladders occasionally break, then the tanks fill with water just as the old style ones do, and become water logged. The procedure is to turn off the electricity to the pump, start a tap running, and drain as much water off as possible, till there's no pressure left. Then you need to get some compressed air into the tank, via a small air chuck, which you will need to install on the tank if there isn't one, or if you have a newer bladder tank, there's already an air valve in the top, sometimes covered by a small plastic cap. Pump about 40 lbs of pressure into it and then drain more water. A couple of times like that and you can shut up the system, turn the pump back on and it should come up fine. The procedure reintroduces enough air back into the top of the tank to make the system work as designed. I have a couple of customers on the lakes around here that have me do this very thing every couple years. Good luck

Answer 3

the motor sounds like it is trying to work, there are thermal links that kick out if the ampereeage go to high a circiut breaker of sort, when they kool down it trys again ,is this a well pump make sure it is primed

Answer 4

Your motor is dead in the water

Answer 5

The motor is shot...get a new one
