Older Maytag won't keep running

[theripster]

I have an older Maytag, model number DE107. It starts when the knob is pushed in, but a soon as the knob is released it stops.

I have taken the motor control box off the motor and opened it up. I dressed up the points with an old dressing file that I used to use on motorcycle points and put it back together. I will re-install it in the morning and test it.

Just sort of wanting someone to tell me that maybe I did the right thing. If not, then what should I be looking at?

Thanks in advance as always. :)

Since it stops when you release the knob. The knob is where I would start looking

Are you saying that the current for the motor should be running through the push to start switch all the time? :confused:

I was under the impression that this switch would work like a cars ignition switch. It shuts another much heavier duty switch(in the starter celenoid) that actually holds the high current needed for the starter motor.

Not an expert on the circutry but you can start and stop the washer using this knob. It works until you let go of the knob. The knob is where I would start.

I guess I should have clarified a little more. It's a dryer, not a washer. I looked on the schematic and it says the push to start switch is only "momentary contact". It must have the momentary contact or it wouldn't start, but whatever is supposed to close and stay closed doesn't seem to be doing it's job. I would assume it's the control mechanism(small black box) mounted on the motor with about 8 wires coming off it that should then be maintaining the contact. At any rate dressing the contacts inside it hasn't made a difference. The door switch also seems to be in order. :(

You may have a motor run winding open or a bad timer. Would need to take a meter and check per the schematic. Just turn power off ist and check for continuity of the run winding and the timer contacts for the motor.

Sorry I haven't gotten back on this. I've been tied up with other things. I need to open this up and start checking again. I do have one question though.

If I have an open run winding, how does it run as long as I hold the start button in? Wouldn't the open prevent the motor from running at all? :confused:

I have one more question.

Am I correct in thinking that if I find the correct motor terminals on the timer and have continuity, that continuity should continue uninterupted through the entire timer cycle.? :confused:
