Hi, Tom here..I'll do my best to help and opt out if I cannot.
Do you have the model number of your furnace?
Rats...I can't access my Carrier acct. at this time.
Is there a terminal marked 24v?
or...can you tell me what terminals do not have anything connected to them?
Weather maker 8000
Ok...unfortunately I can't get into my Carrier info from here. My fault entirely.
Is there empty terminals on the board and what are they labled?
They are labeled:
PR-1; PR-2; L-1; L-2; COM; SEC-1; SEC-2
I think that is it.
Sec 1 and Sec 2 would be for the secondary or 24 volt side of the transformer.
Did all 4 transformer wires plug into the board?
The transformer lead wires should be color coded.
IF the transformer has plug in connectors on all wires...PR1 and PR2 should be the primary or 115 volt side of the transformer.
If you give me the wire colors I can help you sort that out.
The transformer wire colors are as follows:
Also...does there happen to be a diagram on the back side of one of the service panels?
On the new transformer, the Black and white wires are much heavier than on the old one.
OK...Black to PR1....White to PR2 Red to Sec 1 blue to Sec2 should get it going. L1 and L2 are for the 115 volt power from the breaker
Do they have plug in connectors on them?
L1 and L2 are heavier, and go to a connector on the furnace.
That sounds right.
OK, I will hook them up as you suggest. Thanks for your assistance.
I do not know how to bring it back up.
Got it now. Thanks a bunch.
I was on with Tom, Which is which on two "L's" L-1, L-2, black or white to which?
