If the dryer has a button that says "Push to Start", and you push it and nothing happens, the centrifugal start switch is bad. If you can get to it, and it is an "assembled" switch (as opposed to molded or sonically welded), you can disassemble it and clean it with electrical contact cleaner (available at the large retailers). That will fix it for awhile - possible a long while. But it is not terribly expensive, and to order the factory specified replacement switch for it online is a permanent fix.

Where can you get a replacement centrifugal switch for an Emerson motor?

What is used on a single phase induction motor to disconnect the start winding after the motor starts?
A centrifugal switch, once the motor reaches near run speed, centrifugal force causes a set of contacts to open and disconnect the start capacitors. Some larger motors use a contactor which is disconnected by the centrifugal switch.
Why you cant have a centrifugal switch in a hermetic motor?
The hermetic compressor cannot use a centrifugal switch like an open motor because it will disrupt the start winding. Hermetic compressors work through insulated motor terminals, and not in the open.
Why can't you have a centrifugal switch inside a hermetic compressor motor?
The centrifugal switch is likely to wear out and require replacement. It could also create a spark which could cause fumes from the oil inside the motor
How does the centrifugal switch work in a single phase electric motor?
In a single phase electric motor, the centrifugal switch allows the start winding to be energized through the start capacitor when the motor is starting. This gives an out of phase magnetic field that, along with the in phase magnetic field from the run winding, helps the rotor to begin spinning. Once the rotor reaches a certain speed, the centrifugal switch changes state and cuts off the start winding. At that point, the motor continues running only through its run winding, and inertia keeps the rotor properly phase biased relative to the run winding's magnetic field.
The device which disconnects the start winding in some split-phase motor circuits after a preset speed is obtained is the?
It is called a centrifugal switch. The switch is in series with the start winding. When the RPM of the motor reaches a certain speed the switch drops the start winding of the motor out of the circuit.
What is centrifugal motor?
"Clem Motor"
What is the advantage in running a 3pH motor on a 1pH circuit?
The 3PH motor has no internal contacts for a centrifugal switch and are therefore more durable when switched on and off frequently,
What is a centrifugal motor?
A centrifugal motor is a motor that David Unaipon invented for his people but couldn't be created because he doesn't have enough money
What to do when the windshield wipers don't move when you turn the switch on?
check the wiper fuse. then check the switch, then check the wiper motor
What is the use of centrifugal switch in single phase induction motors do all single phase motors gave them?
To stop a three-phase motor dead ('plugging'), rather than allowing it to slow to a stop, the motor controller interchanges two of the three lines -which applies a reverse torque to the machine. But before the motor then gets a chance to reverse direction, the centrifugal switch trips the starter and removes the supply. <<>> The centrifugal switch that you refer to and can see in an open frame motor, is used to open the start winding of small HP single phase motors. Once the motor gets up to a certain RPM, the switch opens and the motor continues to operate on its run winding. When the motor stops, the switch goes back to its normally closed position in the start winding and awaits the next start operation.
What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
