    GFI TRIPPED? THERMAL OVERLOAD ON MOTOR? ARE YOU GETTING 220 VOLTS TO THE MOTOR WHEN YOU ARE SUPPOSED TO. DOES THE WATER LEVEL HAVE TO BE A CERTAIN HEIGHT FOR IT TO WORK - MAYBE FLOAT SWITCH?

    Hi, Do you have a model for the pump? Have you checked the brushes if it has any? How about the impeller? Have you checked the impeller area to see if it sucked up some foreign object? Can you move the impeller? Get back to me and let me know what you find. Good Luck!

Check the start switch on the end inside the motor. If the contacts are scorched they become non conductive. 4000 grid sandpaper will clean them. Rivets in the pc board material can also loose connection. Contacts are polished so sanding them is a stop gap. The centrifugal part of the switch could also fail. That is the part that contacts the start sw.

Check for three potential problems. Bad capacitors and or leaking in-tank check valve or low voltage. Check voltage with meter. On 220 v systems you could have lost one leg giving you only 110v. Check caps with meter and verify that they are within 90% of rating. Finally, if the checkvalve is leaking air back into pump, motor will not overcome pressure at start. If no pressure in the tank, the motor will start even with bad checkvalve. Good luck

Breaker trips when you try to start compressor motor spins a little before tripping breaker


Just fixed my compressor. It would start ok when the tank was empty but trip the breaker if it tried to start with pressure. Searched and read about weak caps, or problem with check valve or pressure switch leaving pressure in the pump head, etc. Turned out that the black plastic box which holds the 2 start up caps and is attached to the end of the motor with 2 screws had cracked on the bottom. The black box had tilted out enough that the start up caps switch was not engaging. Pushed on the lower part of the box and it started perfectly. Fixed it for the cost of some 2 part epoxy. Maybe not your fail, but definitely worth checking out first.

BELT SLIPPING ON FLYWHEEL WHEN HOT


To solve the problem, first check the basic requirements for good function. The deflection of the belt should be 1/64 per inch of span between the centerpoint of the two pulleys. An example, if pulleys are 12" apart, the deflection is aprox 3/16". Next check for air leaks. With air in the tank at about cut out pressure, shut down unit and listen carefully for leaks (spray with soapy water) and repair as needed. Most likely leak is at the in-tank check valve. Remove the airline from the check valve and apply soapy water. If the check valve is leaking the pump with work extra hard to fill the tank. Clean the valve or replace if leaking. If no leaks, then suspect reed valves or head gasket. If reed valves or head gasket are leaking internally, the unit will take longer to fill and the discharge tube will be very hot. To keep track of the overall condition of your unit, you should know how much time it takes to reach cutout pressure. Ideal would be to time the unit when new then retest every month. If unit begins to take longer to fill, you know that a component is failing. Finally check that mounting bolts are tight and brace is not broken or cracked (some compressors have a very thin mounting plate causing the motor or pump to vibrate and the belt to wobble, a brace is added from the top of the pump to motor or motor mount). Good luck and let me know what you find.

Mdl.919.165250need to change wiring from 110v to220vshow wiring diagram for compresor


Your compressor was made by Porter Cable for Sears. The motor / pump is used on many different compressor models depending on tank size and style options. None of the models /including yours/ were ever designed for 115/220v. I did happen to see a compressor that was built for european destination that was 220v. It was easy to identify because it had a two round prong male plug (it could not be wired for 115v however). Good Luck

I have a brand new IR compressor model 2475N7.5 with a 7.5 hp 460v 3 ph motor. is it possible to convert it to a single phase power supply? or should i just exchange it? ... I ordered it thru Northern Tool...


When you google home made 3 phase converters, you will find many ways to make use of 220v single phase instead, however you are limited as to the hp that the motor will produce. If you spin the motor first then apply 220v, the motor will continue to turn at much reduced hp. You need full power to turn a type 30 pump depending on pulley combination/ setup. Best to return the unit and get one that will run on 220v single phase. It will most likely consume more power to do the same work however it would cost a great deal to install 3 phase. Most likely not even available at all. Many years ago, I worked at Sears and happened to see an electrician coming down from roof access of building. He told me that sears had a 3 phase generator being turned by a 220v single phase motor to run an air conditioning unit. He said that it worked quite well. Does not sound cost effective.

Hi

You either have something blocking the pump propellors or the pump itself has failed.

You need to get to the pump. I suggest laying the machine on its back. Disconnect the power and hoses before hand.

There is a cap on the pump, where it joins to the filter cavity. You need to unscrew that cap. I believe they are star shaped screws. Once you remove the cap, look to see if anything has gone through the filter and blocked the propellors. Alot of times it may be a hair pin or some small object. If there is nothing there, then I suggest replacing the pump. Make sure when you are putting the pump back on, that you have the O-ring sealer in place.

good luck

Why the air in air compressor get hot while it's running?and then compressor shuts off no matter what the air pressure is.please help.thank you.


Your motor is running hot. Air blow it to clean it. Some motors require to be oiled on a regular basis. Check to see if yours is one of them. It helps too to rid your tank of the acumulated water.

Compressor will not start


It is a good sign that the motor turns freely with and without air. That indicates that you have good bearings and that the intank check valve is in good condition. Next you should check the capacitors and the condition of the windings. Some motors have start and run capacitors and others only have run cap. Remove from the circuit and test with meter having cap. test setting. Most shops will test them for free. The cap should test within 95% of stated ( uf ) value. Replace as needed. Finally check that the flyball switch at rear inside of motor is functioning correctly. At rest, switch is at start winding, then a split second after start, it shifts to run winding. Check contacts are not stuck and that switch is working and lastly that the winding are the color of new penny. Good luck.
