Maytag Neptune MAH5500AWW washer.

I bought a Maytag Neptune MAH5500AWW front loading washer in November of 2000.

In March of 2002 the motor control board failed. The control board and motor were replaced at no cost to myself. The parts were covered by Maytag, and the travel and labor picked up by a free extended warranty offered by my credit card.

In November of 2004 the triac and resistor that drive the wax motor that locks the door during operation of the washer cooked. I knew these components were covered under a class action suit. I contacted Maytag and they replaced the main control board and wax motor free of charge. I didn't think to mention the moldy door boot at the time. I think that was covered under the class action suit as well. Oh Well!

See closeup image above of the main control board showing the R11 resistor and Q6 triac. This triac and resistor drive the wax motor that locks the door when the washer is in operation.

In September of 2006 a power mosfet located on the motor control board that drives one of the phases of the main motor blew out. The washer still worked but made a cool growling sound when the motor was running and the washer's performance decreased.
The motor is a 3 phase motor and only 2 of the phases were powering it.

I called Maytag because I knew this was also covered by the same class action suit that covered the wax motor and control board that I had replaced back in 2004 under the class action suit. I was told that I had never signed up back in 2004 to be covered by the suit. So calling to have something fixed in 2004 under the class action suit and Maytag fixing it is not the same as signing up for the class action suit.
If I couldn't fix the washer myself, I probably would have found the conversation with the Maytag rep less entertaining.
I generally like fixing my own stuff anyway! Whatever!!!
