      [Webinar] Samurai's Sealed System Sleuthing Secrets - 10/30/2017 @7PM ET   10/19/2017

      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

Help troubleshooting treadmill with GE 1/2 hp motor

Recommended Posts

scconsulting

Ok, I know the first answer to this is : take it to a junkyard or scrap the metal. But I am determined to make this work regardless if it makes sense or not at this point. Now that that's out of the way...This is an old treadmill from like 1988, and it worked until about 5 seconds before I loaded it up and brought it home. Didn't really see a spark or flash or anything, it just stopped like a normal stop if you pushed the stop button. I picked up a new relay because it was just a few bucks and they had it at my local elect.supply store. I swapped it in with no results. I've checked pretty much every wire and switch that I could with an ohm meter. But I don't understand what the relay does inside or why it's there. Or how the stop button works (whether pushing it is supposed to open or close the switch, but right now the way it is wired it opens the switch when you push it. The master power is closed in the on position and open in the off position. The "start" bump switch is closed when you push it and open when you let go. The "reset" breaker doesn't seem to do anything, but it meters closed and I bypassed it once an tried that with no result. I read on another site to rotate the motor manually and see if it produces voltage, and it does. So I don't know where to start next. Any ideas would be greatly appreciated. Here are some pics and sadly hand drawn wiring detail....I can post the drawings with more detail, but with the 500K limit this is all I can post for now.

With the Main Power Switch ON

and the Start Switch momentarily pushed ON

The Relay should energize, and stay energized unless the Stop Switch is pushed

When the Relay is energized, there should be 120v AC at the Motor:

Red to White

It's getting late, I will try tomorrow to see if the relay energizes when I close the start switch. And just to clarify when the stop button is pushed it is supposed to open? and this is what you are saying will de-energize the relay? thanks again, I will check back tomorrow.

Well I got it fixed....and I feel like a total idiot. I knew in my heart everything was metering out correctly...just didn't trust myself. Turns out the main power cable running from the motor up to the panel had a big chunk out of it. In some speed positions I guess it was chaffing on the main drive pulley. Looked like a rat chewed through half the cable...I never saw it because it was in a tiny dark hard to access gap. So I cut it, stripped the 3 wires and reconnected them with the twister type caps...taped it up and boom...fired right up first time I hit the switch. I want to thank you again for the help...Even though it was a simple problem, I would have just given up before I found it if I hadn't found your site. It's totally awesome, and I'm glad I paid for a membership. Maybe we can dig into my toaster in the next month or so! LOL! Can't thank you enough... :dazzler::thumbsup::thanks::rocker: :rocker: :rocker::thanks::thumbsup::dazzler::woohoo:
