Dryer motor testing
« on: May 02, 2020, 11:14:03 AM »

 I have a dryer motor  with model number S58NXMZD-6910 and p/n 40099801  that I salvaged from a junk dryer. I need to test this to see if it is usable. Can someone give me some help on which terminals on the connection block are the appropriate ones to use for the 110 volt input ?

It's actually a Whirlpool part # 279827, a very common dryer motor. To test, neutral to terminal 5, L1 to terminal 4

Hooked up a set of lead for 110 volt to the terminals , mentioned and the motor would not turn  and also started to emit smoke. Looks like this unit is scrap/

Did you remember to bridge the start and run windings? If it is split phase you might have been trying to hard start it on run but if you donít bridge then itíll over current being stuck on start but it would trip the TOL anyways after it smoked Either way then it would reset after about 2 minutes.
