Oh honorable teacher,
I have read the posts and am seeking guidance.
I have a Frigidaire Washer that was not spinning. I read the post and checked the coin catcher (made my self a handsome $2.25 in coins) As it was noted in another post, I turned on the machine and unplugged it and I was able to open the door.
I replaced the door lock, and five minutes later all was working.
Life was good.
A week later, the washer stopped spinning mid cycle. I ran the diagnostics and got E52 = "bad signal from tacho generator"
Now, I need to "Disconnect the plug from the drive motor and measure the resistance pins 4&5 in the motor"
umm, I'm not sure how to get to the drive motor, or where the 4 & 5 pins are.
Also, the washing machine has just complete a load of laundry while I was typing this, so it's an intermittent problem.
