Whirlpool motor wiring question

[maytag85]

Hello all, this is my first thread in the Imperial forum index on the ‘new’ AW site. Awhile back, I created a thread in regards to the older vs newer Whirlpool 29” dryer motors on the old AW site, almost done with the Mark 18 conversion to my Whirlpool dryer. While I did check to make sure everything is wired up correctly (essentially transferred the wiring harness from the Mark 18 to the ‘63 dryer cabinet), the thing that has me stumped is the wiring to the motor. While the color coding appears to be the same (2 red wires for the heater circuit, black for live, blue for common, white for neutral), it appears that 5M, 6M, 4M are different since 6M is neutral to the wiring diagram from 1963 and 4M is the neutral to the wiring diagram from 1977 that was forwarded by Ben. Just want to double check since I don’t want to ruin the original motor from 1963.

The first photo is a wiring diagram from my friend Richard’s dryer (same dryer), second is the one in the service manual that Ben forwarded to me awhile back. Third photo is how it’s wired up currently at the moment.

As long as the two red heater wires are on the correct terminals it doesn’t matter where the other wires are. It’s either gonna work or not if it doesn’t work use a different combination.

As long as the two red heater wires are on the correct terminals you can’t hurt anything. Try it out if it doesn’t work use a different combination of wires on the remaining two power terminals for the motor.

That’s what I might do. It appears that I got the to wires for the heater circuit correct, along with wire 5M. More than likely wires 4M and 6M may need to be reversed if they aren’t correct.

Will have to convert it over to 120v since I don’t have 240v available in the garage.

The machine is essentially all back together, though need to figure what terminals need to be moved over for 120v operation.

Line two to neutral for 120 volt operation. In other words the terminal block wire that goes down the motor's centrifugal switch gets hooked to the incoming neutral.


Wire that goes up to the timer gets connected to your incoming hot.


At 120 volts you will get 1/4 the heating output.

More so just to see if the motor will work, along with the auto dry features possibly.

Got the wires moved over (had to move L1 over to the right, L2 to the left), now just have to plug it in to see if it’ll work.

Plugged it in and…nothing. About the only thing that works is the drum light, relay was engaging, but nothing else.

Looks like I’ll have to do some digging to see why it’s not wanting to work.
