My Maytag washer model LAT9235AAE
, Serial 1377674 QM (may also be referred to as a “Newton” machine) suddenly stopped working in wash mode. When I set the dial to start a wash cycle and pull out the knob, nothing happens. But when I turn it to spin it discharges water and spins as normal. I pulled the front cover and inspected the motor but saw no issues of lose wires or corrosion. In fact this machine is surprisingly clean.
I pulled the cover off the upper control panel and found the 4-amp fuse mounted to the lid switch and off-balance switch assembly, and it was blown. I didn’t have a replacement so I jumper-ed across the fuse with needle nose pliers and produced a small spark. However the machine did not start a wash cycle. Hope I didn’t screw something else up.
I did an ohm test across the small white lid switch (black and red spade clips). Ohms shows “closed” when the lid is down and open when the lid is up. There is a 3rd white wire on this white switch that goes back to the 4 amp fuse bus bar. Don’t know why?
I also ohm tested the black rectangular “off balance” switch. It shows “ohm closed” when the lid is closed and “open” when the lid is open. The wire colors are red on one side and black on the other.
In my limited appliance experience it seems like the lid switch tests indicate the switches are good. But it’s blowing the 4 amp fuse. Is there something else to look for down line of this perhaps at the motor switching, or water level diaphragm switch, etc?
What I am trying to figure out is “what and how” to test the most common things that fail on these machines. If there is something more than the lid switch assembly broken, I don’t want to find out each problem through a process of buying multiple parts as a substitute for trouble shooting flow chart method. I want to try and test everything possible and verify with reasonable certainty what needs to be replaced in total. That way if there are numerous issues, this old machine might have to be retired.
Would appreciate any suggestions. I did get the service manual thanks to this forum but the trouble shooting section seems designed for those with advanced knowledge of appliance repair.
