Another homefill problem with video

[Jar-Jar]

i have this homefill thats giving me a issue i cant seem to find the answer on. when its pumping it pumps fine with good pressure but it keeps switching from O2 below normal to filling every couple seconds. I know the problem is not my oxy con it works fine on other compressors. i have shorted out the o2 sensor but have the same problem. any help will be appreciated

What kind of concentrator? Did you let it warm up for 30 minutes prior to connecting it? Do you have another concentrator that you can swap it out with for testing?

i have a platinum, and yeah i do wait 30 mins for the purity of the oxy con, and yes i have tested on both of my oxy cons i have same issue. i know 100% its not my oxy con cuz i have another homefill thats pumping fine but its probably close to toast cuz it takes like 2 days to fill with that unit

you need to turn the oxy meter on the front of your oxy con down below two. that regulator on the front shows you what it is pushing out of the front, not what it is feeding out of the back to your homefill. 99% this is your problem. you can even turn it off all the way in the front, but I like to leave it cracked just incase the homefill fails, there is less chance it will damage your oxycon. hope that works

I dont even let mine warm up.

also, never get rid of your O2 sensor, thats one of the great things about the machines IMO

the o2 sensor just leaks oxygen.

If it were my homefill in the video i would, plug the fan motor into a 120 volt ac power outlet, bypassing the sensor and the circuit board. You can't bypass the o2 sensor like kovacsglass did because not all machines are the same. The only sure way to bypass the o2 sensor and all the other circuit board is to just plug in the fan directly. It's 120 volt fan so it plugs into standard outlets. The connector you want to plug into 120 v/ac power supply looks like this, and is coming from the fan motor. You can still use the same on/off switch, you'll just need to wire it in. The delay will no longer be present, and it will pump immediately when turned on. This bypasses the pressure switch that turns everything off when full, so you'll need to watch your fill times and pressures.

so you are saying that the o2 meter is basically just saying wether or not there is some gas or another passing through the machine, it does not actually monitor oxygen purity??

thats not my problem i have it set to only 1lpm. im pretty seasoned when it comes to operating these things but fixing them i have had difficulty with

the o2 sensor is measuring for pure oxygen it wont fill if the purity is below 90% i think is the number

It probably does monitor purity.

Most o2 concentrators also monitor the purity, so in my opinion it's not always needed.

It bleeds off a little oxygen naturally. I'm not saying that it will drastically increase your fill rate, but it does leak a little. Also you can hook the machine up to a timer easily in the manner i described without worrying about the annoying beeping(you can also unhook the beeper). If the purity sensor casing gets loose from the circuit board it will cause it to cycle from filling to low o2. Usually you can push the casing back onto the circuit board.

Yes just overide everything and directly wire motor and cooling fan.

[Jar-Jar]

on mine the casing is on fine. im thinking about just pulling the circuit board off a old machine i have and put it on this one to see if its the board causing the issue

You previously stated that the concentrators is producing good oxygen because another homefill works off of it. Based on that i would assume that your concentrator is fine. Hooking the fan motor up directly will force it to fill, but yes you will need to manually shut it off or set it on a timer.

good point, i forgot about the cooling fan. That is a must. It is also 120 v/ac, so you can just wire it to the fan wires.

i got what your saying now i re read what you wrote and it all makes sense now. barry do you know how to replace the bearing on that wheel thing i have another machine that has broken bearing

Of course it's the board. That's the only option. If you indeed hooked the concentrator to another homefill and it worked.

yes. It's really easy. If you can get it down to basically just the hub/and motor mount. You could take it to a auto repair shop, or another repair shop that replaces bearings. Show them what you have, and see what they say. I would tell them it's a compressor and leave it at that. If it gets dirty or something like that, clean it with 409, or some other degreaser.

I changed mine but not everyone is into that kinda thing. I use a hammer, a block of wood(2x4), a socket the same size as the roller bearing and that's it. Installation was basically the opposite of removal. If you have ever changed the bearings on a bike(crank) or the wheal bearings of a car, it's very similar.

thanks for your help barry

Whoops! Wrong one! Gimme a sec to upload the right one.

What happened? I was stoked for the repair manual...

[shawnette]

It's posted ^^

[LooseSeal Baller]

Yeehaw...it tells you how to change a ziptie...it doesn't provide anything useful. IMO

[Swim]

I have not had a chance to look, is there really nothing there?

It may not be helpful to you, but it may help others.

No. It has some simple troubleshooting and parts replacement information. It's a level 1 tech manual.

lets just put it that the manual is not going to help anyone repair a homefill. Unless your homefill has a loose hose. It actually detours you from working on any parts that may actually need replacing. It states that only a "qualified" technician can perform those repairs.

It doesn't tell you how to replace the spring energized PTFE push rod seals, or the roller bearing.

Just saying don't get your hopes up. I've been there

[Kovacs Glass]

If you're already futzing around under the case, it would be an idea to familiarise yourself with what is what and where.

Buying a couple spare sce101 2rs bearings wouldn't be a bad shout. Maybe even install some water cooling coils to your compression chambers.
