Yes I did.
Yes I did
That is correct.
No no voltage at XFMR.
Yes the black wire goes from XFMR to the transformer.
Id like to add that when I connect the black transformer wire to HUM instead, the board does power on.
How should the door switch be wired, I know one wire to line. But the other wire was going to the exhaust blower. Does that make sense?-
Ok, I think I may just have to add a wire to the switch tthat hooks to power. Maybe its different then the way the old one hooked up.
The black line thats currently connected from door switch to the exhaust fan, where do I plug that into on the board so it comes on when the heat comes on.
Yes, the black was plugged into the door switch and the white is connected to 120 VAC neutral.
I'm thinking the installers did something funny during the install back in 98 thats causing me problems now.
I think running a live wire to the switch, and hooking up theblack wire from the exhaust blower to a pin on the board might solve the problem. I'm thining the EAC pin? Which used to be ACC on the old board
You mean the 6-pin to 4-pin? Yes I do. That hooks up directly to the main power coming in.
The 6 to 4 adapter plugs right into the board, that adapter plugs right into the house power supply.
I'm just going by what the manual says where to hook the switch to. It was on 120 VAC HOT on the old board, but the diagram in the manual says that 120 VAC HOT is now LINE on the new board.
From what I can tell, the switch does not have power, thats why the board is not powering on. After powering the switch, it should turn on I would think. Now to figure out where the black line from the exhaust blower plugs in.
Thats an image of the board thats labeled. Where would the black wire coming from the exhaust fan plug in?. This is a hot line, put 120 through the line and the blower powered on.
This hot black wire is supposed to be plugged into a terminal somewhere. It was before. It powers on the fan. There is no way to connect it to the 4 pin plug unless I would splice it in.
It is a plug.
But, the male end thats plugged into the plug coming from the exhaust is just two wires, one white, and one black. Both wires have normal connectors on the end to hook them up to a terminal.
I have to head off to work, Ill deal with this tomorrow. I'm sure it just something simple thats being missed.
OK just wanted to let you know I've solved the problem. I had the plug that was going to the exhaust blower mixed up with the plug that goes to the main house power. They are the same. It was wired correctly on the board and door switch, just plugged into the wrong plugs. Stupid mistake
Thanks for your last answer, it got me thinking about it and discovered the problem.
