A Maytag FB10 garburator and the switch is ...

This answer was rated:

A Maytag FB10 garburator and the switch is malfunctioning. It won''t turn off. The only way to turn it off is to shut off the power to the devise. What is the most likely cause of this problem? What parts do I most likely need? Are these parts available?

This model is a batch machine with some sort of magnetic switch and the devise turns on when the sink drain plug is put in the sink drain (ie the top of the garburator) That is when it is working properly.

If you have to go to the breaker to turn the power off, then you need to replace the switch on your contertop. Once you replace this switch, it will work just fine.

Hope this helps you out. If you need further assistance with this question or just need further clarification - please don’t hesitate to ask.

Reply to Joseph's Post: Your answer does not help in this situation. There is no switch at the contertop. This is a batch machine and the switch is built into the garburator. The garburator turns on when the drain plug is inserted into the top of the garburator. It is some kind of a magnetic switch built right into the garburator.

I do apologize. This is out of my realm I am going to opt out so another expert can jump in. Good Luck!!

Hi and Welcome to Just Answer,


Ok, let's take a look at this;

I see that Joseph has OPTED OUT, I will see if this will help you further

What I think the problem is, is that the "Automatic On Switch" is failing as you suspect, here is the part you will need to replace


Also here is a parts layout to help you see what you need to do to get to that switch, see part 8-18 of the drawing. Once you have replaced the switch it should shut off normally.

Thank you for that information. It is very helpful.

One more piece of information. The plate on my garburator says that it is Model FB10 and SERIES 06.
When I go on-line and look at the list of parts there is a part "Relay-Start & Overload (Series 06)"
Is this the part I need or do I need the part you specified in your earlier email.


There is two auto relays in this unit, the parts breakdown is for the 06 series as you noted, the second one you mentioned looks like it has to do more with the overload, then the actual autostart, I don't see off hand where there is any difference except for the series 1, but it has been my experience with relays, that if you have one going out, and you are going to spend a few hours to replace it, you are best off to change all relays why you are already in there. My thought still are on the upper relay I mentioned first, this is the one that would be the first choice to be your problem in my opinion.
