Where can I buy a replacement centrifugal switch (PMS 004-01) for a Samaung dryer motor

From what you describe, it could be several different problems. Rarely is it the push to start switch. The most likely scenario is that the centrifugal switch on the motor is not working correctly. The other scenario would be the timer. There should be a schematic located somewhere inside the control console. Look for the wires that go to the motor's centrifugal switch and the start button. Jumper the centrifugal switch on the motor so that the dryer thinks the motor is turning all the time. Then, test it by powering it on and pushing the start button. If the motor keeps running, then it's the centrifugal switch, if it shuts off, then it's most likely the timer.

Good luck!

The problem is likely with the centrifugal switch on the dryer motor. This switch connects the start winding of the motor which provides additional torque at startup. Once the dryer is up to speed, the switch disconnects the start winding. If it malfunctions, the dryer will not turn and the motor will hum. By spinning the drum, you are providing enough torque for the start winding to be able to take over and bring the dryer up to speed.

You may be able to correct this by simply lubricating the centrifugal switch which may be sticking. I am not sure if the centrifugal switch is replacable, or if a new motor is necessary if lubricating does not solve your problem

You may be able to solve this if you can lubricate the centrifugal switch with a spray lubricant. If not, you may have to replace the motor. I do not know if the centrifugal switch assembly can be replaced.

Hi,

Check that the motor is turning. If not turning, is it humming? If humming, then the problem is likely start winding or centrifugal switch failure. Try lubricating centrifugal switch if stuck. If that does not work, replace motor. Be sure to disconnect dryer before working on it. Centrifugal switch assembly is located in the motor frame on the shaft.

Good day,
The dryer start switch, starts the motor by bypassing the centrifugal
switch built into the motor. Once the motor is running, releasing the switch doesn't matter because the motor gets it's power directly from the timer to the motor thru the centrifugal switch.

Either the switch on the consul has welded the contacts, or the centrifugal switch in the motor has done the same.

To test, unplug, and access the start switch. remove one of the wires from the switch, tape it to prevent shorting, and try the dryer. If it fails to start, then it is the switch.
If it still does the same thing as before, it is the centrifugal switch in the motor.

Good day,
When you push the start switch, power is sent to the motor directly.
When released the centrifugal switch mounted on the motor has another electrical path to that power wire, and keeps it running.
The switch has failed.
With complete model number, you can call to see if you can buy only the switch, but more likely you'll have to replace the motor.
Sorry about that.
Jack....

you have a bad motor the centrifugal switch in the motor is stuck and the only thing you can do is buy a new motor but it is probably more feasible to buy a new dryer

You cant get the switch seperate for that motor, you have to get a whole new motor.

When you turn your start switch it gives temporary power to the motor and then centrifugal switch in the motor kicks in and gives power to the motor until the timer stops it or the door is opened.Your motor centrifugal switch could be bad due to poor contact or heavy linting in and around the motor.Vacuum inside the dryer specially around the motor. If it doesn't fix it you have to buy a new motor, centrifugal switch cannot be bought separately.
