New clarke keeps cutting out

[mike 109444]

remove load

If the compressor is belt drive, try removing the belt and running it. Atleast if it runs then you will know that the motor is ok under "noload" and will allow you to progress with the fault finding. Don't forget it's very cold at this time of year so oil in pump will be thicker and cylinders being very cold will be tighter. If motor runs ok then try disconnecting pump to tank so pump is not under much load, and go from there (may be ok once warmed up by running under no load) Hope this helps MG

Tried this mate. I took off the belt, ran the motor on its own and it still cuts out only it does last for longer but not much maybe 10-15 secs

Duff motor or cap.

Duff motor or cap.

Or centrifugal switch on the **** end of the motor, have you been able to test or renew the caps yet.

It's more than likely a permanent split capacitor motor so wouldn't have a switch, most small induction motors don't these days.

Yes mate it has split capacitors. Haven't had a chance to check them yet. Hopefully I'll get it done tmw night or Sat
Thanks for the replies

Sorry my mistake, seeing its a compressor I thought high starting torque, and two capacitors I took that to mean Cap start/Cap run motor

Right update on this: I took the motor apart and its burn't out so I've taken it to be repaired. The guy said that it could be the non return valve made the motor burn out.
What do you guys think?
I don't want this happening again anytime soon
Thanks

Edit: Caps were ok afterall

Then fit a contactor with an overload as motor protection.
