Our treadmill is acting up. I found a place that can repair the circuit board. They maybe messed up when they asked if there was a blue capacitor in line to the motor. It may be bad. It is actually on the circuit board. 1.500 uf and 250 volts. About 2 5/8" tall and about 1 3/8" in diameter. Where to find one? I would like to put in a new cap before I send out the board for repair. I can send a picture if anyone needs one. It is your typically large sized cap in the blue can.
One trick I devised a long time ago (I'm sure others do it). Once the old component is removed heat up the solder on the board one hole at a time and quickly blow real hard at the board close to your mouth. Blows the melted solder out and the new component usually goes right in the holes. You might have to do it a few times.

That is why we have desoldering braid and vacuum bulbs. ( tho i stopped using bulbs after i grew up )
The noise in my opinion is the brushes. My opinion was the signal from the board was bad. It is a simple brush motor. Same as hand drills etc. In my opinion the feed from the board is erratic and causes the brushes to bounce or something??
I sent some emails to some local electric repair places. A guy called and offered some suggestions. He says it is not the board. Maybe a lifted commentator. He says disconnect the drive belt and rotate the motor. If it makes the noise twice per revolution it is a raised commentator. So maybe I will need a new armature. New motor is $500. New armature is still probably $300 I bet. I think I am on track now to getting it fixed.
PS: replacing that capacitor was a joy. The board was clear coated and the capacitor was glued around the rim to the circuit board. I had to pry it up slightly with a screw driver while I heated one leg. Then use a scalpel to cut the glue joint. Then heat each leg etc. But I got it.

Thanks Rodney
Should have told us why you were doing it in the first place Would be free to check out the motor...
I took a cover off the motor and could look at the armature/brush area. One commentator is burned. Since I can't get a new armature for this motor I decided to try cutting the wire to that commentator. The motor still worked but once I got on the fuse in my house electrical panel blew. So this motor is junk unfortunately. So I'm going to buy a new motor. But I thought it was the board so I'm ahead. New motor is big bucks but without it the treadmill is junk. We bought it like new used for a bargain price so not the worst.
New motor is in. Works like new. Just one of those things. Something shorted in a winding. But no service call and got it right the first time so no not needed parts were bought and tried. Well I did put in a new capacitor that was not needed and I have 2 spare capacitors now. But that was not that much compared to buying a new $500 control board or a service call by a tech.
