How to Troubleshoot & Replace Whirlpool AP6006265 / WP22002119 Wax Motor

Replaced wax motor and circuit board 

Verified that wax motor had power and ground, witch it did. Checked resistance value of wax motor, was about 1200 ohms. Seems to be correct value. Ordered new wax motor and asked tech line about it. They pretty much insisted it was The $214 Control Board. I questioned there judgement, they asked me to inspect the control board for burnt components. It did in fact have a few burnt resistors. I replaced Control Board and wax motor, It corrected the Problem. 

Replaced the motor wax door lock switch and the door lock spin enable switch. 

Changed wax motor but did not work.changed circuit board and solved problem 

Changed out the wax motor and the door switch. Works perfect now. Thank you. 

Saw the YouTube videos and saw it could be 1 of 2 parts. I decided since one part, the motor-wax wasn't very expensive to get, I bought the motor-wax and also the drain pump assembly. Replaced the motor-wax and tried a load but it still wouldn't drain. Replaced the drain pump and bingo I now have a working washing machine. The biggest challenge was getting the drain tubing off the old drain pump. Found that heating the tube with a hairdryer made the tubing more pliable and it came off. 

Replaced wax motor switch and door lock switch. 

We replaced the door lock wax motor, the control board, a new belt as the machine was 20 years old. 

Replaced the main control board and wax motor (with the black plunger). Also, while having the machine exoskeleton off, checked connection tightness and cleaned with wd-40 electronic cleaning spray all connections, start button, timer etc. Then carefully replaced the wax motor (the most difficult thing was getting the darn spring out--till I ascertained that the back of the spring was in a slot--compressed the spring and used a screwdriver to pry it up and out); marked all the connectors to the old board with sequential numbers before removing to be sure they got on the right connectors on the control board. Put the board back in (top right of my unit which was a Maytag Stacked Washer/Dryer Model MLG2000AWW-vintage--about 2002) buttoned up the remaining panels(two screws went missing somehow so had to improvise a bit with substitutes that would fit and do the job) Then, having reassembled the machine, because I had suspicions that the starter button might be a culprit, pushed it and to my surprise--it went on--then called wife and set the timer, pushed the button and Eureka--it sprung to life and went through the entire cycle perfectly!! All smiles--and the 1/2 hr or so I spent monitoring the trial cycle was worth the time in satisfaction for a job completed and well done--KUDOS to AppliancePartsPros for their courteous service on the phone and for getting it promptly here in a couple of days--and especially for their parts functioning as advertised. 

First tested the control board above the dryer in my stacked Neptune. Q6 Triac and R11 resistor looked and tested fine. Then tested micro switches above washer door. One was bad. replaced it and the still working original wax motor for good measure. Total repair including tests about an hour. But I've had this apart before...
