Troubleshooting why this old 2004 Craftsman 919.167311, 30 gallon, 6-peak HP, air compressor keeps tripping breakers at startup and after running for a few minutes. Most of the time it will be one of the two capacitors that go bad but I've changed these in the last year.

Part I--- "A" for effort, "D minus" for theory. Here goes- The black cap is a START cap, The silver caps are RUN caps. START caps are rated above 70MFD and have their capacitance in a range . Your Mallory and Packard are 400-480MFD . RUN caps are rated below 70MFD and have an exact capacitance. Yours are 40MFD. Replacement must be exact for RUN caps. START caps have a 10% acceptable tolerance. Voltage ratings of replacement caps can be higher but not lower than original. The "safety switch" at 4:45 is actually the centrifigal switch for the caps. At around 75% of full speed the START cap de-energizes and the RUN cap takes over. If your replacement RUN cap is not exact or is not energizing, the motor will run hot, pop the cap, trip the breaker, or burn up the motor windings. I also noticed @ 4:45 the winding switch is missing the right side contact leaf. Not sure there ever was one on your motor. See Part II

Hello I need help troubleshooting my compressor please

@steadyeddie7453 2 жыл бұрын

Part II- If the unloader valve is bad it will leave pressure at the head, making the compressor hard to start and trip the breaker. The unloader is what makes the hissing when the compressor reaches its cut out pressure and shuts off. Finally, the arm behind the cooling fins is a counterweight. It smoothes out the motion of the piston. Similar to a harmonic balancer on the front of an engine. Considering your comp starts and runs for a while before it cuts out I would say there's a problem in the centrifugal switch assembly (as long as your replacement caps are correct and wired properly). Oh, and I would confirm the actual contact switch in the cover uses only one contact leaf, and doesn't need two. Cheers.

@Comm0ut Жыл бұрын

I have one of those cheap POS (at least I bought it used and got some use from it) and the unloader was indeed bad. I've other compressors so it's a storage tank for the end of long air hoses (at which it works nicely). If I fix it I'll use better parts. BTW the person directly responsible for ruining Sears is Eddie Lampert, may he smoke cocks in hell (to put it more gently than deserved) when he finally kicks the bucket.

I gave it it's own, dedicated 20A circuit, 12 gauge wire, 20A breaker, recep is 6 feet from the breaker. Ran great for years, but now, it has started to trip the 20A breaker on restarts. I haven't checked it yet, but I'm betting on capacitor.

Similar problem for years. Trips breaker only on startup... sometimes cold. Compressor is on 1st floor and am now reshingleing roof. I know I"ve got a tripped breaker when the nail gun won't drive in the nail. Off the roof and down the stairs to hit the breaker and it starts up every time. This is my second compressor bought from Sears. My first one had pump issues and I needed another one immediately and got another 30 gal. and had to return it because of an air leak. Replaced it with this one and they run fine until the warranty expired. POS craftsman. I used the old dead pump compressor for a sand blaster sand pot. I've got a great sand blaster now. I think I will find me a 220V 60 gal compressor. Maybe a twin piston. Sorry that your troubleshoot did not work. I was looking for the magic fix. Thanks for your video because you convinced me that I should treat this POS like what it is and get a quality tool.

Hey Tuner try this, in the case that holds the capacitors there is a contact mounted on the bottom, with the cover off press the contact and turn it on, when it starts up release the switch, if that cures your issue than its the broken cover giving you your issue. That switch is closed on start up and when the motor turns the clutch moves in disconnecting that switch.

I had a similar problem with my Craftsman compressor about the same size as yours. Mine tripped the breaker upon startup. A good assumtion was that the starting cap was bad. Not knowing which cap was which, I ordered the running cap instead of the starter cap. After that failed to fix the problem, I bought a capacitor tester online to test the capacitance of the caps. I quickly found that the starter cap was the culprit. I then ordered the starter cap and that fixed the problem. The best practice is to replace a capacitor with the same rating as the old. The manufacturer doesn't matter just the voltage, capacitance range (rated in farads-typically MFD) and farad tolerance percentage. When shopping for a replacement, the physical dimensions are usually noted in the description. The capacitor tester takes the guesswork out of the equation and costs about the same as a capacitor you didn't need.

So I just had the same problem. The switch inside the plastic shroud is what kicks the start capacitor out of the circuit, if you have that sitting too far from the rotating piece inside the shroud it won’t switch from the start capacitor to the run capacitor. On mine the screws holding the shroud broke and it was running on the start capacitor until it burned the capacitor up. I replaced the capacitor, and made some brackets with sheet metal to hold the shroud and switch in the right position. Works like a charm now. That’s probably why you’ve been burning through capacitors.

PROBLEM SOLVED----I have a 2002 craftsman oilless compressor since new, did had the same problem after many years of service and had same thoughts about the pressure switch and the capacitors, to make it short did found the problem, after many years of service the contacts on the back motor cover were dirty, something so simple easy to miss, once I cleaned them with very fine sand paper problem was solved, after that i went ahead and bought the two pistons and cylinders kit (mine has 2), after a number of years again started popping the breakers, and again cleaned those contacts and started again with no problem, when you pulled the back cover I saw the contact metals, do clean them and am sure will work, at first I almost threw away my compressor after all the work same as you but saw another video somebody cleaning those contacts so I went back and cleaned them and it worked, 'till this day I still have the same compressor, hope this helps like it did to me.

@andrewmartino6144 3 жыл бұрын

Hey how's it going? I have a few questions and tips. What is the amp rating on the motor and what is the amp rating on your breaker? Have you checked to see if your breaker is working properly? Over time breakers loose their capacity as the contacts wear down. The more times it trips the more it wears down. Is your 220 a 30 amp breaker? Because it should be. Motors over time wear down, the graphite contactors at the bottom of the windings shaft wear down and sometimes get full of dust and stick and the copper plates of the stater? wear down as well. You have to take the motor apart and clean it up and check the connections and make sure there isn't a short internally. Also if the shaft bearings are shot which likely will happen after 16 years then it would cause the motor to over current. Fun fact, you can take the entire motor/compressor off of your tank and get a new multi piston compressor with a belt driven shaft and hook up any 110 or 220 motor to it. If you're worried about compressions efficiency with a 110v single stage 5 amp motor, all you have to do is change the pulley ratio. Smaller pulley and bigger pulley. One more thing to troubleshoot is to disconnect the armature for the piston assembly and run the motor. If it doesn't trip then its the compressor itself.

@TunerwithKids 3 жыл бұрын

Thanks for the insight. I haven’t thought of it that far. My first inclination was to see if their are replacement motors (there’s not). Aside from that, ideally I’ll probably get by with this until I can find a used industrial 220V IR compressor. Then I’ll use this as a spare storage tank.

I have a brand new compressor its 20gal, same amps (I wont go into how its smaller, less cfm, more draw despite it being larger..maybe because of the pump being oiled V-2 design..whatever). It will not run on my circuit. It barely gets to 80psi, and once the motor needs to work a little more, it pops the breaker. I am using a HD extension cord, and maybe thats enough, but Im in an old garage, and even though the wiring in fairly new, its still just 15A only. So, Im trying to think of all kinds of cheats on how to lower the draw of the motor...even if that will further decrease perfomance. I do need over 100psi (at least 120 for tires and air system diagnostics). The other stuff? I have to rely on electric tools... At this point, Im debating cranking up my generator and running the compressor off that, but in the winter, fumes and all...not my idea of fun.

I watched this video attempting to troubleshoot why my same compressor was tripping a breaker. I found that the black case that secures the capacitors was the culprit. that small switch on the inside between the capacitors Has to be in full contact with the motor or it continuously draws too much power tripping the breaker. Just like your compressor the mounting screws for that black plastic peaks were broken. Allowing the capacitor mount to float freely. I was able to secure that plate with a few large zip ties and it has not tripped a breakersince. That was two weeks ago

Mine ran fine all the other times I replaced capacitors but recently acted up again. I’m probably gonna try new caps one more time to see it that’s the culprit. Since I infrequently use my compressor, I think that the caps end up going bad.

@@TunerwithKids is the outlet your plugged into a dedicated 15 amp or higher breaker? Meaning- One outlet wired directly to the breaker box? NO other sources on the same power line?

No it’s for half the garage. But I also have a chest freezer attached to the same circuit. The breaker is right there in the garage so it’s a short run.

The problem is with the disk on the armature and the contact switch that it engages with on the plastic cover. I'll attach the link from the article I found on how to adjust the switch. It's not a capacitor problem like I thought too. www.bobvila.com/posts/41656-6-hp-30-gal-1-stage-compressor-won-t-start-trips-breaker-fyi#reply_top

@@jeffreyeyer1971 I read through all of the post you left the link too but unfortunately I can’t visually comprehend what Steve was saying to fix. Do you happen to have the photos or where the washers needs to go? Or the bottom of the housing that breaks and people push in and fix that’s mentioned on a comment later in the post? Thanks for the post.

Is it just me? I think we're asking a lot from that 120VAC circuit, on a 6HP motor, especially upon restarts, when it is under partial load to begin with.

@TunerwithKids 3 жыл бұрын

These motors aren’t really 6HP, they are barely 2HP. It’s marketing, it peak 6HP just like all the vacuums and other stuff that claim HP.

The foam you have stuffed into your intake is to restrictive. Try replacing it with the correct or equivalent air filter.

check induction motor bearings a step you didn't take, they are sealed but as they wear out, the grease leaks out into the armature. It will be as good as new when replaced. I'll confirm this as thats my project for today on mine. POST EDIT: My electric motor is toast the stator windings are shorted...

Your problem is called a turn to turn short on the run winding on your electric motor. essentially your run and start winding has a short. If you have a meter test your resistance ohms your common to start and run to start resistance will be very similar. New motor needed.

That switch is a centrifugal switch that cuts out the start winding when it reaches speed. It is not a safety switch. My compressor motor end cap which holds the capacitors and the switch broke off the end of the motor so that it would start with little pressure in the tank but after it cut off it would not restart and then it would trip. I am rigging up a way to retain the end cap on the motor. The endcap should be made of heavier material so it would not break so easily.

Naw, it ended up being capacitors. Very common issue and I had a follow up video like 1 year after. The run cap needs to be exact value to balance the motor load or it overheats and trips any breaker.

I would advise people to having the problem of a breaker tripping to put a plug in meter in outlet that reads current. A lot of those 12-15 amp rated motors will actually draw 15-20 amps when the compressor starts to load up on air. 20 amp breaker and 12ga wire should be used with a 13-15 amp motor.

In short : craftman/ sears should be ashamed of not selling or procuring replacements to the run capacitor. My compressor is slightly different and there used to be a capacitor replacement kit D30107. I am about to just trash that motor and replace it with something from Grainger.

They capacitors are usually off the shelf commodity items that can be purchased anywhere. See links in description for some options. One of the caps is an odd size so I just bought cheapest one and made it work. The correct physical sized one wasn’t worth the extra money.

Hard to measure capacitors with a MM. also, we have over current issues tripping the breaker, so most MM aren’t rated for that high of amps in Current mode.
