E Calvert we use a clamp style amp neater clipped over the neural wire. Set the meter to AC amps and turn on the motor each different size motor will have it’s expected amp draw typically listed on the mfg label. On the K9 II dryer for example it says 17 amps or 8.5 per motor. As for OHM readings they can vary slightly from motor to motor of the same model number. But on an individual motor the important reading to keep is all windings on that motor must be within 10% resistance to each other. Finding one set outside the 10% average can cause the high amp draw or possibly trip breakers.
In order to change the back brushes, you must remove the two brackets that hold the front motor in place. Then you will pull the front motor out through the front of the housing. You must be careful of the wires as they will most likely not be long enough for the motor to sit down on the table. Usually we sit the motor on the leg (usually I have the dryer standing on the back end while I do this repair). Looking down through the tube of the housing, you can see the front of the back motor. You will have to first use a flat screwdriver to slide the brush tabs out of the brushes, then remove the screws and take the retaining brackets off. Remove the old brush, slide the new brushes in place *make sure you catch the brush wire into the slot on the new brush while installing it*. Once it is in place, put the retaining bracket and screws back in, and finish pushing the brush tab/wire tight into place. Then you can replace the front motor and put the brackets in.
@@TheEdgePro thank you! The only other video I've found on UA-cam about the back motor brushes has me taking the back housing apart, all the wires and switches and taking the whole thing out.

How often should the brushes be replaced? What other maintenance should I be doing amd when?
Is there a filter to replace?
How do I remove the motor?
which end is the easy end? I can't figure this out at all. the hose end wont come off and the other end looks nothing like this.
how do we find someone to do this for us? I am not about to pull motors out myself.
How do you test the load on motor, amp draw. What is the OMS per segment?

I also managed to break the brass crimp connector. Anyone know the part number and/or where I can buy a replacement?

@@lilynunya9449 You are welcome!
My wires are so short I can’t get the front motor out. What’s the secret?
Despite watching & rewatching this video, I managed to break the hook off the brass tab. 🤦♀️ Help!
What an absolutely bs design. Hours of labor with poorly designed garbage. No wonder people just buy cheap Chinese dryers.
