Machine tumbles but does not spin up to full speed. I troubleshot IAW Maytag service manual and replaced motor control board from known good machine. Worked fine for a week but now has same problem. Measured motor windings, found them good according to service manual. Measured tach output from motor pins 4 & 5 and found them open, service manual calls for 155-195 ohms. Maytag service manual troubleshooting tree does not address this condition. Is the tach output required for operation or is it used as part of the help mode that provides failure codes? No diagnostic (failure) codes given when using service mode.
