Topic tags/keywords: dust collector dust collection electrical breaker remote start

I’d like to get a little feedback if anyone has any ideas (not usually a problem here).

I bought a Delta 50-760 Dust Collector about a year and a half ago. Like most everyone, I tweak the 4” system a little here and a little there.

I added a remote start switch about 6 months ago and love it! About 2 weeks ago I fired the DC up with the remote and heard a “click”. The small breaker on the remote switch box had flipped. Thinking that the switch might have gone bad, I removed it from the DC and plugged the DC directly into the wall. Wrongo!

When I flipped the switch on the DC it started up but seemed to be dragging. The startup was really slow. Then the 20amp breaker in the breaker box flipped. I reset it and tried again. Again it started up slowly, but it did start up and ran fine.

For the last 2 weeks I’ve been running back and forth resetting the breaker. The DC will usually start up eventually. I know I have been ignoring a problem but just haven’t gotten around to properly diagnosing it.

Now, the second the DC is switched on, the breaker flips and there is no coaxing it into starting up. Does this ring a bell for anyone? Is the motor going/gone out? Is the bearing going/gone out and causing the fan to drag resulting in increased load? Am I full of beans and completely on the wrong track (a likely possibility)?

Any suggestions?

You may have saw dust built up in the motor, time to get an air hose out.

I second the idea of cleaning it up. If that doesn’t work, then check all electrical connections in the DC and make sure they are all tight.

Sounds like it could be a starting capacitor problem, maybe the cover is full of dust. Becareful though, I think they might hold a charge, I would check first to see if it’s true before digging into it. If you are useing an extension cord, is it the right size ? Have you added any other tool to that electrical circuit that would put the whole circuit under a load when attempting to use the dc ? Is the impeller clean ? Wet treated lumber will accumulate on the impeller. It’s hard to say without being there to actually see what it is you have got going on.

Could also be the centrifugal switch in the motor. If it’s stuck in the open position and doesn’t close when the motor stops spinning the next time you turn it on there’s no power to the start winding. I had this happen on a 2HP Marathon motor.

If you can somehow coax it back to life, when you shut it off and it’s spinning down, stand by it until it stops spinning and listen for a click. If you don’t hear a click it could mean that the switch is stuck open.

The capacitor should discharge across the windings if I remember correctly. But always be careful around capacitors. Even if they discharge you need to be careful in case you didn’t give it long enough to do so.

Thanks for all the suggestions folks! I’ll start by getting into what I can and clean it like mad. Blank, I don’t think it’s the centrifugal switch because it does “click” when winding down. I kind of thought that might be some sort of switch disengaging and you confirmed it. Thanks!

I’ll let you know what I find and whether I need more ideas or whether it’s back up and running!

could temperature changes be a factor now that it is getting hot out?

Durnik, did you buy it new? If you had it a year and a half it’s still in the 2 year warranty. When it comes to motors though, Delta usually wants it returned to verify it’s bad and you might have to pay shipping. If you have a DeWalt Service Center near you or a Delta authorized repair center or the motor manufacturers authorized service center, you might be able to do that to avoid shipping costs.

Blank. I did buy it new (Rockler). I’ll dig out the warranty info. Thanks for the tip. For some reason I thought it was only one year.
Hokie. I’m in Colorado and it really hasn’t warmed up significantly yet. We just had a snow yesterday! Once it gets started it runs fine and I haven’t noticed any inordinate heat.

These are excellent questions and you guys have given me a lot to explore! I’ll let you know.

Most Delta stuff always had at least a 2 year, then they started the X5 with the 5 year warranty. It comes with a 5 year warranty now. If it was purchased after January 1st, 2009 or if its date code is on or after 200818 (May 1st, 2008) it then qualifies for the 5 year warranty.

Well, I disassembled the DC down to anything that didn’t appear to be sealed up. I pulled off both of the bags as well as the input hoses. Cleaned like mad. There was a little “cake” in the impeller chamber but nothing significant.
I opened the top of the motor and the fan and bearing appear to be moving freely. I didn’t go any further into the motor itself since it looked to be factory sealed.
I then popped open the switch housing. There was extremely little buildup in there and everything seemed to be attached well. I did see the capacitor sitting in there since it was marked “Capacitor.” I’m pretty sharp on things like that.
After the cleaning I tried firing it up and the breaker flipped. I was able to coax it up to speed and stay on after about 3 tries. It seems to be the initial start up that is bogging things down. I’m leaning toward the capacitor since everything spins right and moves freely. If anyone has any other ideas, I’m open to anything.
I’ll call Delta on Monday and see what they have to say about covering it under warranty. I looked it up and I have had the unit for 17 months so I should be good under the 2 yr warranty. I’ll let you know.

If you can “coax” it on, it’s the starting swith that flips from the start to the run windings.

You guys are a little late joining the party, I think he’s having Delta deal with the motor since it’s still under warranty. But I’d be interested in hearing the outcome.
