Single Stage dead??

Just been running my single stage and the compressor has just stopped i have just opened up the electrical box and theres a large capacitor, could that of failed?? How do i test?? Not sure if my mm has a capacitance reading.

The fans still spins but nothing else, it just cut out, no pop or anything.

Did you happen to turn it off and back on within a short period of time or did it just stop and you've not turned it on again since?

I made the mistake of turning it on too soon after I turned it off and the fuse popped which is meant to happen. Maybe your fuse went, so check that first.

No mate it was running whilst i was switching a gpu out, like the compressor part stopped and the fan was still going. It was quiet for a change!!

I would of thought its pretty old now?? So something was bound to let go

If i connect mm on ohm setting to capacitor it drops to 0 and then starts to rise and keeps going??

I'm no electronics engineer but that doesn't sound right to me. Perhaps it has lost its charging ability.

Oh, I know, that rotary is ****ing loud. It performs like a beast though.

Hopefully someone else can help you here.

Have seen a new 1hp rotary R22, does that sound about right?? Can i post links here??

I think that one is 1hp too, but I don't remember. There should be a sticker on there somewhere if memory serves, but I could be mistaken.

Of course you can post links on here.

The sticker does not say much

Very similar to this one http://airmend-hvac.en.made-in-china.com/product/eSyniZMlLPkL/China-T3-Rotary-Compressor-R22-220-240V-50Hz-1HP-3HP-LG-Compressor-QP407PAA-.html

Brendan, is there a fuse for the compressor?? If so can you remember where?? Had one guy at MLG say to wire up compressor direct to mains to test?

Oh my, now you're asking! LOL.

It's within the electrics box, but I can't tell you where exactly. I think it's in the white junction box. I had to replace it once myself.

Are these the fuses?

I honestly can't remember and I'm taking stabs in the dark here.

Try looking under the live terminal closest to the earth. I think it needs to be unscrewed.

I can't logically think where else it could be, but you may be able to spot it.

Perhaps a bit of resistance probing with your DMM will do the trick. Find out where the link is broken and base your search around that.

Found it!! You were correct! Fuse ok but 1 of the contacts was a bit slack so i bent it in and not sure if that was the problem but its working, testing now and currently at -57c i'll see how long it lasts. Thanks for your help!

Glad to be of assistance. Now you know where it is in case you pop the fuse in the future.

On another note: Damn, I miss that unit.

What, i can't hear you!!

Well played, Nick. Well played.

Ha ha no seriously thanks, got a new board and chip coming in next couple of days and i would of been truly gutted if it were fubar, so fingers crossed its all good and i can rag this new hardware still building upto LN2 but work needs to pick up a bit before i start throwing the $$$$ at that.

Whereabouts are you based, Nick? I assume further north like most overclockers.

Oh, new hardware? Do tell me more.

Also, add me on Skype. I assume you have it.

Based near Lincoln, have never used skype mate but never say never, got a lot to learn yet and want to keep pushing. just grabbed an X58 platform to thrash, just building up my hardware before making the jump, thought about DICE but lewis reckons i'm not gonna gain much as far as cpu(SS) is concerned. Just need to get volt modding then i'm set to have a bash, just always hard work being a privateer funding everything. Dagmar has been very helpful in that respect regards hardware but i generally refuse as i dont like being responsible for other peoples stuff but i may borrow his dewar and of course knowledge

Lewis is right, going from that phase to DICE is not worth it at all. I did it, and it was a waste of £70 on the DICE.

It's an expensive game, without any doubt. Even more so when you slaughter a GPU before you even use it.

Sounds like a plan. You're welcome to venture down to my place to have a day with LN2 if you wish. It's a long way down though.

I've already slaughtered a very good 680lightning which is why i have been buying older/cheaper cards to test with. And i appreceiate your kind offer, will have to take you up on that you still in the states??

Oh dear. How did that happen?

That's definitely the way to go. I bought a 780 Ti from Ian though so we will see what happens with that.

I am, yeah. I'll be back next week but I can't get any LN2 until the beginnining of April, unless Lewis can find another supplier as he wants to come down too.

I couldn't wait to get suitable sized bolts to connect the SS so i drilled the holes bigger on the card, still not sure what killed it but possibly static.

Where are you based?? Do mansfield cryogenics deliver to where you are?? Viz uses 'em and he's way down. http://mansfieldcryogenics.com

they do deliver there but the problem was that they weren't in the area anywhere near when I was planning to go. They're on a 6 week schedule in brendans place and I was planning on coming right in the middle of said schedule

I doubt static killed it, I think you're more likely to have severed a few traces that lay underneath the visible PCB.

Truly gutting and a great shame. You'll know better next time buddy. It hurts, doesn't it?

Nick, get Skype. Us three need to have a chat so we can organise a meet!

nope wasn't a track, I already looked over it for that and was extremely unlikely to be that.

I do actually maybe have another theory, nick you haven't thrown that card yet have you?
