Your fan motor part number is 4681A20040J manufacturered by LG.
This motor is also found in Goldstar dehumidifiers, which, according to the service manual, bear a striking resemblance (not a coincidence) to your Kenmore dehumidifer (same manufacturer).
The Goldstar Service Manual is located
here. The fan motor is item 34681 across all the models. Take a look at the circuit board itself. One side of the motor is connected directly to the AC incoming, and there are 2 relays that control high and low speeds (2 windings).
So, your fan motor is 120vac operated, if you are not getting power to the fan, then the relays are suspect.
Have fun with the info, I did trying to find everything.
