Customer Questions & Answers

I have a problem with this compressor tripping the reset button all the time!whats the deal?

Seems like you may use a min. Amount of air and it wants to replace it right away but when it goes to start it sounds like it is under a load and will trip the reset, is this a warranty issue? I am thinking so! Any ideas, thanks Doug
Asked by: Anonymous
I appreciate all of the great answers. Mine was on a 15 amp breaker at first, so I plugged it in to a 20 amp dedicated breaker. Bought it in May of 2013, and problem came up after about 1 1/2 years. I can't find the receipt to return for warranty, so what next? When pressure is building up, and all three tanks are connected, breaker pops, and air bleeds out of the switch housing. Every single time. On the web site, there are quite a number of unhappy people with the same problem

How much does this unit weigh to be carried? Does it separate?

Asked by: blue
It does separate into 2 parts. It's easy enough to separate...but I don't usually bother. The unit is heavy...but you can carry it. I wouldn't want to be hauling it around all the time. It's heavier than it looks. I think it probably should have wheels...would be more convenient and mobile. When separated, it is easier to carry. It's just not simple enough to do quickly.

Also allows you to take the tank to remote locations and not have to drag the pump also. I purchased it for a small wood shop for nailing and spray painting. It will get a inline filter and separator before I get to paint again.

Rated 1 out of 5 by from compressor broke 8 months of use. normal operation, no abuse to compressor, just broke. This is the second Ridgid compressor I have owned. The first one broke ( reed valve failed and destroyed the piston and cylinder) took it back to get it replaced, out of luck had to buy a new one. Thought I would give Ridgid one more chance, Bought the Tri Stack unit. Broke after very light normal use after 8 months. Was still under warranty, was fixed and returned in 4 weeks. Suggestion for Ridgid. Replace compressor when customer brings it back for repair. I had to buy another compressor to use while my damaged one was being repaired. I will not buy another Ridgid tool..... I hope that the repaired compressor will last for years to come but I,m not counting on it.

Rated 4 out of 5 by from Happy so Far After reading all 73 of the previous reviews I decided to give this compressor a shot. Purchased on 8/28/13. I recently sold a larger gas compressor and a smaller pancake compressor and was looking for something smaller that would fit the bill for what I need now, something in between. I have several years experience as a framing and trim carpenter and business owner. I have other Ridgid tools, some of them are good, some of them are just not up to par with tools like Bosch or Milwaukee. I was hesitant about the purchase because of the repeated problems others mentioned, then again, some people either don't read directions, or are simply just not supposed to own tools. I did one thing that was not mentioned in the directions of this compressor, but has been in every other oil free compressor that I have had, 4 gallon, 20 gallon and 32 gallon, (all different manufacturers) and that was to break in the motor and compressor. This is done by opening all the drain valves and turning the compressor on and letting run without the added resistance of building pressure for 15 minutes straight. Monitor your electrical connection as it should not get too warm, and the air that cools the motor which comes out the side. It may get warm, but not hot. The air coming out of the drain, particularly the small .5 gallon tank drain on the compressor unit will be warm since really, that is where all the air is coming out of. After 15 minutes, turn the switch to off, close the drains, turn back on and allow the unit to come up to full pressure. (if it seems excessively hot, let it cool, if the wiring is hot, your home wiring is inadequate.) I haven't had the chance to really put this thing to the test yet, but I cycled it several times, watching all the gauges making sure they are going down equally, then back up equally when the motor cycles. If the gauges are moving at completely different paces (some discrepancy would be normal), there may be some type of obstruction in one of the lines connecting each of the components. I would consider this a manufacturing flaw and would take it back to Home Depot with in the 90 day satisfaction guarantee period. The heck with dealing with a warranty if you just purchased it. That's easy for me to say, I'm 5 minutes from my Home Depot, which is why I figured I would try this one out. For now, mine is running just fine in an 11 year old home with modern wiring and breakers. It is on a 15amp circuit and I didn't experience any of the aforementioned power, or non-starting problems. I didn't really find it louder than other oil free compressors that can push this type of CFM, they are all loud, that is just the nature of the beast. I separated and replaced the top and bottom unit several times and had no reconnection problems. It is heavier than what I would consider a trim compressor, but it comes apart easily, making it easier to carry. The next compressor up, the 4.5 gal 200psi Dewalt 5 CFM@90psi is heavier than this one (it has wheels) and is much larger. I was looking for something a little more storage friendly with a minimum of 4 CFM @90psi, so this one was a better fit. I also love the versatility of being able to run 2 separate pressures. I always hated running back to change pressure when switching tools! I say try the break in method before you use the compressor and see if that works for you! I will write a follow up review if I experience any problems after using it for a while, especially at different locations where the wiring may not be as good. If you don't see a review entitled "Happy so Far, follow up", all is good!

Rated 5 out of 5 by from Good design. NOT "idiot proof" though i've been using this compressor for about 6 months now, and i've read mixed reviews about it: i wanted to share my personal experiences with it. its an amazing design as most ridgid products are. splitting the unit in 2 makes it so much easier to carry... which leads me to my first negative comment for pretty much any ridgid product: this compressor is super heavy for its size. not a problem since we all carry heavy stuff all day, right? splitting it in 2 actually helps this tremendously. 3 air ports is key, just make sure to read the manual as it explains which ones provide optimal use depending on the job. ive seen 2 of these things "fall apart" as some people describe it. what that means is the handle on the top comes loose... well Ridgid was kind enough to provide a fix for this issue. its called a manual. step one in the manual: Assembly. complete step one, and you have a sturdy, rock solid handle that will never come loose. another problem i've heard is that it draws so much power. it actually does. its a very powerful compressor; it fills in no time. to prevent beaker trips, it requires a heavy gauge cord, OR it MUST be plugged directly in an outlet. again, read the manual... i should note the unit is loud. compressors are loud, but this is very loud. i plug the unit directly in the outlet, split it in 2, and convert it into a piggyback compressor. again, its all in the manual. final thought: i'm well aware of the flaws of this compressor, so i can work around them (plugging it directly, completing step one in the manual, etc.) so personally, i think the great features outweigh the flaws. if you read the manual though... there are no flaws. 4.5 out of 5

Rated 5 out of 5 by from Great Buy!! I was on a job using a framer when my 6gal 2hp air comp. went out. I look around everywhere and couldn't really find a good a compressor for the money. So I got on home depot and other sites and found this comp. I have only had it a few days but already notice a huge power gain. I was kinda leery about buying this one because of the tank coming apart from the motor, but It works flawlessly... I love it! It isn't any louder then another comp. its size, just a little heavier. But since it does come apart it is great to carry, instead of one u have to lug on your hip. Great Deal JarrodG
