My Kenmore washer (series 90) stopped working in between the rinse and spin cycles. It will not drain (half full as we speak), agitate or spin. It will fill with water but once it reaches the proper water level there is a humming/buzzing sound for about 20-30 seconds and then silence. I have also noticed a slight burnt plastic smell around that time. Ideas?

Hi Norm. Welcome to FixYa.
The first thing to check with the kind of symptoms your machine exhibits is the operation of the lid switch. Make sure that the pin/plunger on the lid itself has not broken off, and check the actuator lever on the switch itself. It is REALLY common on your model for the actuator arm to break off or crack, and this will cause no spin/no pump problems. Your machine is built by Whirlpool and the part number for the switch assembly is a 3849238. You can get it at any local whirlpool parts center in your area.

I hope you find this info helpful and thank you for allowing us to serve you.

Happy New Year from the FixYa crew!

Kenmore 90 series model 110.28912791 stops and wont spin

SOURCE: Kenmore front-load washer stops at rinse cycle

When the washer initially fills for the wash, is it only hot water entering the drum? Try switching the water temperature between hot and cold as it fills. If any of them show little or no water getting through, it sounds too easy but check to make sure water supply taps are on, and that the cold/hot fill hoses aren't reversed. Remove the fill hoses and check any of the screen filters for blockage (in the hoses and in the inlet water valve). When the machine stops and waits to fill but all you hear is a hum, it sounds like there is power going to the valve but water is not able to get through it.
Good luck!

A washer that fills and doesn't do anything, or stops right after the wash cycle and then does not advance to the rinse cycle and drain is commonly caused by a lid switch malfunction. The lid switch is usually mounted under the washer top casing, on the right hand side on most top load models. It is activated by a plastic piece on the lid (called a "Lid Strike") through a small hole on the rim of the wash tub opening. In many cases the lid strike breaks off the lid, or the lid switch becomes loose and no longer makes contact. Inspect the lid to make sure the lid strike is still intact, and then inspect the mounting screws (adjacent to the small opening on the wash tub rim) and make sure they are snug. If you determine the switch to be defective, the following link explains how to replace one:
