I have a Trane XL90 model TUC100B960A0 Furnace. I was told by "HVAC Guru" (justanswer.com HVAC Technician) in May that my board needed to be replaced due to non-start condition. I have purchased a White Rogers Model 50E47-843 to replace my White Rogers Model 50E47-060. I am having problems identifying the correct wire conversion from the old to new board.

L2 - Ground to frame via pigtail included in replacement board kit
HS2 - Not used
FP - White wire to flame Sensor
L1 - Large red wire going to limit control
HS1 - Large blue wire going to Igniter
Customer reply replied 1 year ago
I have the manual. With the wires connected as stated in my previous text it throughts the breaker on the main house panel.
Customer reply replied 1 year ago
Pretty sure I have something crossed somewhere.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Ok. Let me check.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

and Hs2 should have a wire from ignitor on it

Ask Your Own HVAC Question
Customer reply replied 1 year ago
L2 is green going to grounding on furnace cabinet based on note "e" listed at bottom of the table you sent me.
L1 is Large Red Wire going to black wire that goes to main power coming from on/off switch on side of the furnace.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

the note E is if there is NO l2 terminal available. But on this control board there is a L2 terminal.

Ok. I am removing the the green ground to furnace jumper wire I added.
Customer reply replied 1 year ago
Removed.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

You said hs2 was not used...where is the other wire from the ignitor?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Nothing attached to L2 and still throws the breaker.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

where is your white neutral wire that comes into furnace with the black power wire?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
White wire from igniter goes to netral in juction box built into furnace.
Black wire from igniter goes to HS1
Customer reply replied 1 year ago
Power comes in from furnace juntion box to L1
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

ok that is a problem

The white wire from ignitor goes to hsi2

The white wire from neutral box goes to L2

Purge fan is running. No hot ignitor. The ignitor is new. No flame. Purge fan is still running though. I have noting connected to HS2 or TR
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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

Ask Your Own HVAC Question

Purge fan continues to run constant but no hot ignitor. Again. I do not have any wires to blades HS2 or TR

HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
I only have two white wires;One from Ignitor that is currently on L2
One from Flame sensor that is on FP
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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

Ask Your Own HVAC Question
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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

Ask Your Own HVAC Question
Customer reply replied 1 year ago
OK. I am giving you exactly where the the white ignitor wire goes.1. From the ignitor itself it goes up into the funace juction box.
2. It pigtails to a 24V converter.
3. It pigtails and goes to the white wire on the purge motor
4. It pigtails and goes to the incoming white neutral white.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Black wire from ignitor goes directly to HS1.
Black main power goes directly to L1
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

the 2 blacks are fine.

Move ignitor white to HSI 2

Attach neutral to L2

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Roger-
Moving ignitor white to HSI 2
Attach neutral to L2I have to go to the garage and get a new blade to put on the wire to attach it.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

no problem.

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.

Ask Your Own HVAC Question
Customer reply replied 1 year ago
I have wired everything as you stated. Purge fan runs but no ignition. No light comes on the new board either. This is exactly what it was doing in March. I went on justanswer in May and was told the board was bad. Now I replaced the board and nothing has changed. What else could be causing this do you think?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

if you turn thermostat off does purge fan stop?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Turned off the thermostat off completely and purge fan continues to run!
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

ok, this is commonly a tripped safety or open safety.

When this happens is the main blower running?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
OK here is the deal. Purge fan is not running the main furnace fan is running. The AC worked perfectly all through the summer and shut on and off including the furnace. Now I flip to heat and the damn thing has gremlins. If I which it back to AC it works perfectly again.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

Prior to this swap...did the exhaust fan run?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Scratch that. Now the furnace fan runs continuously regardless if the Cool / Off or Heat is picked at the thermostat. It did not do that before replacing the board.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

is there a fuse on the new board?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Not that I see. It is a sealed unit.
Customer reply replied 1 year ago
Shit. The manual switch for the fan was on. Pulled it out now it is on auto. Fan has stopped.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

ok,

so where are we at now as far as operation

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Ok, I switched the thermostat to heat and nothing. No purge fan no light on the control board. Nothing. If I switch it to cool it kicks the furnace fan on and the condenser outside runs.
Customer reply replied 1 year ago
Do I need to check the thermostat for a jumper?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

Thank you. Do you mind removing the top section of thermostat?

OK. There is no jumper. Just the red wire on R. Nothing jumped to R to RC. Should I add a jumper?

tell me if blower starts, and then we will go to circuit board for more testing

Ask Your Own HVAC Question
Customer reply replied 1 year ago
Nothing. No blower or purge fan. Nothing turns on at the furnace.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

I thought with the fan setting in "ON" the blower ran?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
There is a manual/auto button inside the furnace. When I was tracing wires I bumped it in to manual mode and it ran all the time. I have sense pulled it back out to auto mode so that it only operates when the AC or heat calls for it.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

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.

OK I took the relay off and pushed the plunger up and the purge fan started. Still no ingnitor. There is a wiring gremlin in this furnace on the heat side. I am calling it quits. Thank you for all your help.
