maytag Neptune
« on: August 18, 2008, 09:39:28 AM »

Well having fun with the control board.  Replaced it once to have it blow again.  The part that blows is Q6.  I have voltage tested the wax latch motor it is at 16 v.  Manual is listed at 24.  Also tested ohms on wax motor it is at 1100 instead of 1900.  Not sure if it is the wax motor or what Q6 is wired too. Help?

Model MAW4000AWW

The wax motor runs on 120 volts.

Only the spin enable switch in the lock assembly carries 24 volts.

Replace the wax motor and the board. Replacing individual components on the board as suggested by other web sources is a lesson in futility.

Something does not seem correct with your model number.

Are you sure it's not a MAH4000AWWicon?

Here are the parts that Repair-man talked about for that model number.

Was the original Wax Motor ever replaced when the Board was replaced ?

The new Wax Motors have a black plunger.

when the wax motor blows it burns out the resisters in the board. If you fail to replace the wax motor then every board you put on there is gonna blow. The way I understand it is when the wax motor is good it locks the lid. When it goes bad instead of it preventing power to the board it bleeds voltage to that board, frying it. When it goes out then it allows full fledged 120 volts to go into the board and frys it.This is a defect . Later models have been modified with better wax motors. They have a different color to show the modified version.
