Ordered timer for increasingly dysfunctional 20-year-old washing machine based on descriptions of similar problems: certain settings wouldn't work, machine would fill but not agitate, etc. Removed the old timer (the exploded drawings were essential, and a list of required tools would have been helpful. Thankfully, we had the right socket in the garage and replaced it with the new one. Pulling the socket was the most difficult/strenuous part, mostly because I was taking extra care to no break tabs or stress wires any more than necessary. Note: bottom of the panel goes inside the flange during reassembly; it's easy to just screw everything together without thinking about this (and admittedly easy to fix). First test load was heavy, and at first the machine seemed classically overloaded: no agitation, slight burning-rubber smell. Was initially worried that the agitator had somehow been abused to failure, but draining and starting with a lower water level/lighter load proved effective and after about the third load the machine was fully functional and able to handle normal heavy loads. The replacement timer and less than half an hour of slow, conscientious work probably saved more than $250 on a repair visit and who knows how much on a new washing machine.
