One of my antminer s1 upgrade kits isn't working. I think it has something to do with the fact that it is showing 4 chains in the miner status. Please help:

BitMain, there's something seriously wrong with your S2s. When are you going to release firmware to improve their performance 
I have 16 S2s and they all stop hashing several times a day. I have to turn their power off and on to get them to restart. Reboot does not work. I've replaced the underpowered EnerMax PSUs with Corsair AX1200 PSUs so that's not it. You also released them with a ridiculously high queue of 8192 causing huge discards and an api-allow W:0/0 giving hackers easy access.
Is the S2 so unreliable that it dies in just a few months
Are you going to abandon your existing customers or support their purchases
I have a batch 2 S2 that has been mining since 2014-04-17. I replaced the PSU with a Corsair AX1200i, other than that I'm happy with the unit. Rock solid, never goes down.I have 16 S2s and they all stop hashing several times a day. I have to turn their power off and on to get them to restart. Reboot does not work.

Since an S2 draws about 1kW, your farm is producing about 16kW of heat. That's a lot of heat, and I suspect that is the problem.
What temperatures are your S2s running at? Sounds like they are overheating and shutting down. Constantly having to restart them is no fun, and also doesn't solve the problem. The only way to fix this is to get better cooling (more airflow / better heat extraction / etc), or break the farm into different locations.
The good news is that your S2s will shut themselves down due to thermal limits before any damage is done. Once you improve the cooling, all your units will be rock-solid. Try this test: take one trouble unit - one that needs rebooting several times a day - and put it in a different location all by itself (with great cooling / ventilation). Take it home, or put it in a totally different room on the other side of the building, or another building, or something. If it still needs rebooting then cooling isn't your problem. But I'm 99% sure cooling is the problem. It's the major problem of any miner with a big enough farm.
My mine uses 96 kW of power. Temperature is well controlled and ambient heat is not the problem. If anything I suspect it may be due to an issue with house power, but, my S1s and S3s do not suffer this issue. Two days ago I put several S2s on their own 120 V 20 amp circuits distributed across all 3 phases. That has not helped.
Today I'll swap a few AX1200s for AX1200i's and monitor their power.
I still think it's thermal. What temperatures do the S2 show?

My computer is telling me the HTTPS is not there just http and there may be someone trying to steal information. Wants me to click I understand the risks if I go forward. So no I have not logged in. Not sure I should.

Lets wait and see if they adjust the BTC price of the S3+ to make the S4 more attractive. Can't wait to see what they do there. But I hope not, I was planning to try to buy 4 more S3+'s.
They owe me a replacement fan and said they would ship it when I place my next order. Which I told them was fine, but not if they jack the price up.

$1450?!? Ouch. At that price I will stick with the S3+.

Back up--S4 pricing updated to $1450.
Very much not interested at that price.
Agreed 4 x S3+ at the current value if still .58 is only $997, and I have mine clocked at 250 frequency doing 500Gh some under a hair some over a hair in last 24 hours

^^^^ The latest firmware has the frequency select blank. You need to set and save, reboot.
Thank you. Details on how/where to do that please?
Status tab
then Miner configuration
then Advanced Settings (grayed out til you click it)
