Hello,My name is ***** ***** I will do my best to assist you. I am looking over your question now and will respond shortly.
what particular wires do you have an issue with?
Thank you...now just to assist as go along.
Did you have this in with the new control?
MV - mv 1MV- mv2TR -trTH- thFP- fpGND - grndL - L1
ING - hsi
are there others?
does that help at all?
the terminals you have connected are all low voltage and would not trip the breaker except for L1 and L2
Your white wire from power...that needs to go to L2 on the board
and Hs2 should have a wire from ignitor on it
the note E is if there is NO l2 terminal available. But on this control board there is a L2 terminal.
You said hs2 was not used...where is the other wire from the ignitor?
where is your white neutral wire that comes into furnace with the black power wire?
ok that is a problem
The white wire from ignitor goes to hsi2
The white wire from neutral box goes to L2
the white from ignitor that you had in neutral box...that goes in hsi2
And previously you said the white wire from pressure switch was on TR.
Did you move it off
Ok this was mentioned earlier but lets make sure.
White wire from ignitor goes to HSI2
White wire from neutral box goes to L2
White wire from pressure switch you said was on TR but is not now?
The furnace needs 2 main things from the home power system
a black 120v and a white neutral. Both of these have to be on the board...L2 has to have a wire from the incoming white neutral to furnace
the ignitor goes on HSI 2
Before doing anything right now...
Put the white from ignitor on HSI2
we will go one wire at a time.
Once again put the white wire fromignitor on HSI2
We do not want the white ignitor going anywhere except HSI 2 on the board.
Before moving forward...move the white ignitor wire to HSI 2
the 2 blacks are fine.
Move ignitor white to HSI 2
Attach neutral to L2
I have to leave for 15 minutes. If you have another question I will respond as soon as I can.
If you are all set after the switch just rate service at top of page.
if you turn thermostat off does purge fan stop?
ok, this is commonly a tripped safety or open safety.
When this happens is the main blower running?
Prior to this swap...did the exhaust fan run?
is there a fuse on the new board?
so where are we at now as far as operation
Thank you. Do you mind removing the top section of thermostat?
we want a jumper from r to rc........and then we want to cross 2 wires so let me know when you are ready
before we do that...take the red wire and the white wire on W terminal and cross them together. Tell me if the exhaust fan starts
now red to green...
tell me if blower starts, and then we will go to circuit board for more testing
I thought with the fan setting in "ON" the blower ran?
the issue is..
touching red wire to green wire starts the blower even in ac mode.
but your saying the red wire touching the green wire does nothing, so I am at a bit of a loss.
so we know power is right
Now put thermostat back together.
We go to the furnace next.
Door off and pop out safety switch (if present) taped down.
Then with a U shaped wire....we want to put one end on r and other end on w on the board.
R to W at board eliminates the thermostat.
Is there a chance you could take a pic of the furnace with doors off and post here so I can mark test spots
Look at this picture
Take the 2 wires off the switch and connect the wires direct together metal to metal. Then try R to W jumper again
If same with no operation see HERE
put those back...and try the next switch I showed you...also it would be a good time to see if the exhaust motor gets power but does not run.
go back to the r,w,y,b/c termonals (furnace)
set thermostat to heat and turn up temp...
then test terminal B/C to W and tell me if 24v
Attached is a close up of a relay in top section.
With an insulated handle screwdriver or a pencil I want you to move the points I hav an arrow at...by move I mean press until it makes contact with other points
please tell me where the purge fan wires come from
and I apologize but I have to go offline for a while but will respond as soon as I can
