ATW4675YQ1 Admiral Washer

A detailed Service Technician Service Manual is hidden inside the machine on the front panel. It is hidden by the bleach dispenser input. It gives a list of fault codes and instructions for calibration after repair, resetting fault codes, and a manual test mode for stepping the machine through each mode on command. The Tachometer failed which would not let the machine come up to maximum spin speed. The tachometer is part of the solenoid actuator that shifts the transmission. It is not specifically called out in the manual. Any failure causes the lid lock light to blink which gives the appearance of a lid lock failure

Watched a video on the internet.

The instructions that came with the part were worthless. Essentially, unplug, put in new part, plug it back in. I spent a considerable amount of time on the internet and finally found a video showing how to open the top. Unlike other models, it is held down by clamps in the back rather than clips in the front. Once finding this information the installation was simple. Remove the clamps and the back of the console, slide the top forward and lift, remove and replace the lock and reassemble. You don't even have to remove the hoses.
