Is there any place that sells the centrifugal switch by itself? I understand as a rule you have to buy a new motor with centrifugal switch. And I suspect the motor is not being manufactured any more.

Or, is it possible to repair the centrifugal switch?

The centrifugal switch is on the motor shaft and is not a replaceable part.
You may be able to clean any lint and dust from around it then manually move it back and forth to free it up.
The motor is available.

Is the brown plastic device with a number of lugs attached to the motor not related to the run switch? If I understand your post the run switch is internal to the motor?

From reading, I understand that there are two centrifugal switches on dryer motors. One is for starting, and after the motor starts, it disconnects the start circuit. The other switch is a safety feature which ensures that if the motor is not turning, the heat is off.

Is this the way this motor works?

You gota couple of leaf switches inside the black box. The box itself has a metal tab sticking out that you can't see. When the motor takes off the springloaded flyweights get slung outwards and the tab gets released. The 2 leaf switches inside change contacts. One powers the heating element circuit so the motor must be running before the heater comes on. The other make the jump from start to light speed (run). In motors this age the fly weights will stick holding the heater element on till the timer is turned off. Lubricating the sliding flyweights on the shaft can sometimes fix the problem. I have one of those switches on a motor in my shop.

How do you get at them?

Also, can you see that metal tab you mention on the second picture of the motor (view from above), between the shaft and the switch case?
