Replaced rotor position sensor and rotor assembly. Let's put it this way: It took longer to get the dryer onto a dolly and out of the way; the washer onto a dolly and into the garage; my tools out and reverse this procedure. It took less than 6 minutes to swap out the parts with air and electric tools. The final tightening was done with torque wrenches. Plugged it in and: "Wah-la" DONE!
Thanks to this website that offered me the videos on how to repair it and the extremely fast delivery (ordered Monday-received Thursday) I was able to do the repairs that quickly. It appears that LG makes the most sensible and easiest machines to work on! Thank-you.
