    Default Help..Broken micro-switch tab, twice

    My Kenmore softener was consistently running. After looking, I noticed the white tab on the microswitch had broken off. I ordered a new one, installed, and the white tab broke off right away. I was able to epoxy the outer shell back so the switch is fine, but before I reinstall it, I wanted to know what would keep causing the switch to break? It is a Kenmore 625. 348670. The switch does not have the metal arm, just the white button., It does look very tight tolerances when the hub rotates, any ideas?

    The rotor seal is acting like a rubber band when the rotor turns. You need to replace the rotor seal.

    Thanks for the quick reply... I am confused, what does the rotor seal do?
    How would that affect the switch breaking?

    Thanks......

    Did you replace the micro switch with the same kind of micro switch?

    Did the old one have a metal arm or the little white button?
    What is the new one that sears says is the one for your unit?
    Possible that they sent the wrong one?

    i replaced with the exact same switch. Here is the pic. I just got my entire seal kit, replaced rotor seal and orings like stated in earlier post, put new switch on, it made it a few clicks then BROKE again. I know my old switch did not have the tab. I am stumped..... Something caused the switch to break and keep breaking.

    One of the reasons that I am not fond of the sears units....

    Metal cam is still turning in the same direction that it was before..

    First one broke the same way that the second one did...

    I ask about the rotation of the cam becuase I just had to replace a motor that was turning counter clock wise when it should have been doing clock wise... talk about doing a number on the rest of the system....

    Yes, cam is turning the correct clockwise way. both broke the same way. I understand the design, the tapered groove which should slowly press the switch down, but i am at a loss.

    Like wise,,, I am running over a few ideas in the mind...

    The first one or old one might have been because of age, but the second one after a turn or two of the cam.. that is a puzzle.

    Ok, the 2nd broken switch was actually a repaired switch with epoxy after it broke. Remember I bought this switch after the 1st broke, installed it BEFORE I got the rotor seal kit, and it broke.

    So, I installed the new one I just got and it ran the complete cycle last night...so the repair was probably not sufficient... I'll monitor it and let you know. Thanks for the help...
