Lennox G8 reads 55volts at W


I am totally understanding it better now. Thanks so much! Didn't do anything with it last night.. valentine's day.. obligations

I'll be here again next week at which time i'll do the re-wire and report back. Thanks again Yuri.

PS: i made a little youtube video of the 55 volt measurement.. check it out.. that's the Fan Center buzzing! http://www.youtube.com/watch?v=n7ZdoPz_yOk

Yuri.. what if i simply put the white from the gas valve to C instead of R as it is now? I am still curious why the old transformer was left in to power the gas valve.. is there a good reason to do that?

You sound dangerous to me and I don't take kindly to people questioning my instructions. DON'T overthink and follow my instructions EXACTLY. I am leery of you burning your house down by fooling around with your wiring. The old transformer comes with the furnace and is too small to power a fan relay. The fan centre has a bigger transformer. I won't babysit you thru repairing it if you fry it or spend hours teaching you HVAC wiring as you don't know any of the components or what they do. There are Community colleges for that.

Yikes! I'm not questioning your instructions.. i apologize if it appears that way. Just making sure that there isn't a reason that transformer was left in there. After all.. another tech installed the Fan Center lol

Your instructions are fantastic and i thank you for them. The only part that still confuses me a bit is that the "brown wire is closed and pigtailed off". Not sure what you mean by "pigtailed"? The way i picture it, it seems open to me. I know i'm wrong; just wish to know why.

:Dan <-- totally not dangerous.. ..unless cooking dinner

Sorry Man, I am used to training apprentices with some basic knowledge of what we are working with. I cannot help you if I feel you are not following instructions properly and cannot hold your hand over the net and connect the wires for you. I am not sure what the original guy was thinking but it was done wrong and w/o being there cannot straighten it out. I have told you exactly how to wire it and am not going to answer everyone of your questions. Get a tech to wire it for you and make sure all the controls are working properly. The fan centre may be damaged by this setup you have and there is no way I feel this job is going to turn out safely for you or the next guy who buys your house if you leave it miswired. I have dealt with too many DIYers who think a furnace is some fun project like a lawnmower to play with. You don't know what is going on there so get someone who does.

Fair enough.. thanks for all of your efforts. If i decide to call a tech in, at least i know what to tell him.

Now.. all i need to do is find a tech that a) knows the old furnaces, b) is competent, and c) is honest.

Apparently... like most trades, it's hit and miss. And i'm not much of a gambler.

Thanks again,
:Dan

Just wanted to thank you for the instructions. I decided to try the fix myself. Finished the re-wire last night. All works perfect. Since you weren't 100% sure about the gv, I did some research on Honeywell gas valves and confirmed your description. You were right about the terminals TH/TR etc.

The original tech who installed the A/C basically followed the old 2-wire style of wiring, feeding the original the transformer from limit, and adding the new Fan Center.

I have removed the old TR and re-wired as per your directions. Limit control works fine, though it's set a bit higher (220deg).

Thank you,
Dan
