John, I'm going to try and be as succinct as I can, but don't hold me to that. I've been up all night, and, well, you get the idea.
On my t'stat, reading from left to right, the terminals read B, O, G, Y, W, not used, R, RC. The wires had labels from the old t'stat, which was already installed when we moved in here, so I went by those labels when installing the new one. There is some kind of "jumper" across B and O. It looks like 2 very small metal pins joined together. NO WIRES are in those 2 terminals, just the jumper. I also found a very small jumper that looks as though it is made from a very small piece of wire, between R,(the white wire is there, with a "W" label), and RC, (red wire). THAT'S kind of perplexing to me..why would a jumper be there...between R and RC, and a different colored wire in each spot? Anyway, I twisted R, Y, and G together, as you said, however, the wire colors at those 3 terminals are WHITE (R), BLUE (Y), AND GREEN (G), RESPECTIVELY. Again, I went by the labels from the previous t'stat install. After twisting them together, and with the contactor plunger NOT HELD IN BY MY LITTLE ZIP TIE SLIVER, I APPLIED THE 240V. NOTHING. I looked the whole thing over. The VIOLET "low side" transformer wire is wire nutted to one of the 2 YELLOW CONTACTOR COIL WIRES, the BLUE "low side" transformer wire, wire nutted to the WHITE THERMOSTAT WIRE, THAT LEADS TO THE "R" TERMINAL ON THE WALL PLATE. The OTHER YELLOW COIL WIRE IS WIRE NUTTED TO THE RED T'STAT WIRE, LEADING TO THE "RC" ON THE WALL PLATE, AND OUTSIDE, THE GREEN, YELLOW, AND BLUE T'STAT WIRES ARE UNUSED...JUST WRAPPED AROUND THEIR CASING...RED AND WHITE BEING THE ONLY ONES USED AT THE UNIT.
Well, here we go. It's 11:25am. I was outside, letting one of my dogs back inside to eat, and WE heard ( he is shellshocked, so he jumped pretty good ) A LOUD POP. Immediately, I KNEW it came from the A/C. Down the steps, ran over and cut the power. SEE FURTHER, WHAT'S TYPED BELOW WAS HERE.
Well, I just lost an entire paragraph. These are close to the exact words I was writing when I lost it. My keyboard and screen cursor have a mind of their own, subsequently, it can take me upwards of three hours to get an email this size to finally type in, spelled at least close to correctly, and finally sent. Enough about that.
It was 11:20 when I was outside, to let one of my dogs back in to eat, when WE heard a loud POP ( he is shell-shocked, so he jumped pretty good). Immediately, I KNEW it came from the A/C. I ran and cut the power, and FOR THE FIRST TIME, I ACTUALLY SMELLED SOMETHING. Smoke was coming from the transformer. I don't know exactly what was wrong with it before, but it's for dead certain now, FOR STARTERS, IT NEEDS A NEW TRANSFORMER.
This is news that I thought you should know pronto. Man, I've been up all night, AGAIN, screwing with this piece of CRAP. And THAT'S JUST THIS DAMN COMPUTER!!!!!!!!
I'll surely have more, and I'm sorry the delay. I saw that you were wanting to be updated ASAP, but I'm going at a pace that is necessary. I'm only 56, but I am disabled, and things like this WEAR ME OUT BAD! (SEE LAST SENTENCE OF PREVIOUS PARAGRAPH).
So, I'll be in touch constantly, as often as I can, you know. We're as broke as convicts, and we need a 30 or 40 dollar transformer, at the very least, just so we won't have to do without the A/C. It's now close to noon. No sleep, a smoked transformer, and no A/C for who the hell knows how long. THANK GOD IT ISN'T SCORCHING HOT TODAY. 15 or so degrees cooler than normal, and cloudy...overcast.
John, this is a copied and pasted email to another John at another online forum, that is helping me to try and get this over with. It's now 1 o'clock Tuesday.
I made some videos. The files are very large. How can I get them to you. email me
