Craftsman 919.165310 - Fills fine from empty, chugs and blows fuse when restarting on low pressure.
I just acquired a Craftsman 919.165310 for a decent price. When demo'ed the unit worked just fine.
I get it home with air in the tank and it won't start. The compressor tries (think car with low battery) then popped my 15A breaker. My garage was low on amperage anyways with all my stuff, so I ran out to Lowes for materials.
Now I have a shiney new 20A GFCI circuit I just put in. It runs fine from empty, but when you drain air and it tries to start again it fails as mentioned above and blows the circuit.
I've read that GFCI can cause it, so much to the dislike of my pregnant wife I drag it in the house to test with a non-GFCI circuit w/the same problem.
I'm new to compressor DIY fixing. However, I noticed many threads on this matter and no one has said "I fixed it with this..." that I could find. I'll be researching your site but am out of ideas. I've cleaned everything, lubed anything that seemed safe to lube (wd-40) with zero results.
Any help will be appreciated.
Hi Chris. Thanks for visiting this site and taking the time to write in.
Tell me, when your compressor runs from empty and reaches the cut-out pressure level, does the unloader valve work?
This question is a link to the page explaining all about unloader valves, if you're not sure what they are.
If there's pressure in your tank, then there is pressure in the line from the compressor head to the check valve going into your tank.
If the unloader valve doesn't work, then the pressure in the line between the head and tank is also still in the cylinder, pushing down on the compression piston.
If this is the scenario, then what you are doing when trying to start your compressor with pressure in the line is having your electric motor try to start against the load of the compressor itself, and the extra load caused by the air pushing down on the piston - the air that isn't supposed to be there if the unloader valve works.
The electric compressor motor draws amps on inrush to start. If the inrush amp draw is too high, which often happens if the compressor motor is trying to start against additional load, the breaker pops.
Check this out, and let us know how it turns out, OK?

Craftsman 33 Gallon 1.6HP Compressor
Hi there, I bought this compressor from someone and it has very little use on it. Well since I have had it there has been one issue with it that I am trying to get resolved before I take on a bigger project.
When I turn it on its gets up to 150psi which is it's trip point. When I use it and it drops below the trip point the compressor tries to start up again but eventually trips the breaker.
I have tried cleaning the one way valve and it seems to be working correctly. I can also hear the pressure relief when it hits the pressure point.
I do have it hooked up on a heavy duty extension cord but it seems to work fine when there is no load in the tank. I thought it could be an undervoltage but I would think that would affect it when airing up irregardless of tanker pressure.
In conclusion, if I drain the tank completely and then turn it back on it runs like a champ back to 150psi. I appreciate any feedback that you may have.
You've done everything right.... except, did you check to see if the unloader valve was working?
You'll find a link to that page from the sitemap.
From your description, I think ensuring that the unloader valve works when it's supposed to will solve your problem.
