Topic tags/keywords: dust collector hf harbor freight circuit hot

So I think my HF dust collector motor might be going out. I noticed that the circuit breaker had popped so I went and reset it. By the time I got my hearing protection back on it had popped again. So I started to look at my equipment and my HF dust collector motor was hot as hell! The chord that goes from the motor to the outlet was too hot to touch, but the wire in the wall was cool to the touch. So the problem is in the motor right? I just bought this dust collector a couple of months ago and it has been a great dust collector up till now. Any ideas on fixing this problem? Anyone else had this problem? I know it’s a Harbor Freight but I have never heard anything bad about their dust collectors. Please let me know what you guys think.

Here’s hoping you got the extended warranty. -OR- Maybe they cover 90 days anyway.

The power cord being hot and the wall wiring not hot throws up a flag for me.
Would you say the power cord was hotter than the motor?
Could the power cord be loose at the motor connection?
This connection could be bad and making everything else hot and pop the breaker.

BUT, my first guess would still be the motor, just check out the other things first.

Very hard to say since I wasn’t there.

Are you running this with over size ducts or without the bag and exhausting outside?
This will overload the motor as well.

what circuit are you running this on ? 15Amp? 20Amp? 30Amp?

considering this is a 2HP motor, it should probably be AT LEAST 20Amp, but 30 would be better.

Mine has done well. I’d check with the HF store about warrenty.

It was running on a 20 amp, but I bumped it up to a 30 amp. On the 30 amp it does not throw the breaker but it still runs hot as hell. I don’t think I bought the extended warranty. All of the connections are tight, I have checked all. Chord was hotter than the motor but the motor is very hot as well.
