Hello, My name is XXXXX XXXXX I will do my best to help you today.
Was the board you installed a white rodgers 50A55-843 board?
yes it was
in the box there is a supplied jumper wire that you have to insert into the 12 pin plug of the furnace
From R01 to R02 terminals
If not there the furnace thinks there is an open roll out limit and will give you that 5 flash code.
which one is the jumper wire?
I believe it's a small 2-3" white wire that has metal ends. These ends are made to snap into the holes of the 12 pin plug in the furnace that plugs into the 843 board. If you look on the top of the 843 board it has a diagram showing you the names of the terminals of the 12 pin plug.
find R01 and R02 on that diagram and then put the jumper in the corresponding holes of the male 12 pin plug
it is a black wire sorry
i take i they go in the back end of the plug
R02 is a back middle slot with a flat side
The R01 is up 2 spaces form that in the middle
yes, it just slides right in and locks. If you notice on your plug those slots are empty atm
okay. just did that. turned on heat. blowing but no flame ignition
Did the igniter glow?
flame just came on! sweet. no led lights flashing. do you think im good?
yeah you should be.
awesome. thank you so much!
Common overlook with those boards on trane furnaces. There is a small sentence about it in the directions people miss.
no problem at all. Glad I could help
I'll take credit with the wife. we'll keep this $38 charge our secret. ;)
Still having problems with the heater. It worked for a little bit and had problems shutting off today. I replaced the flame sensor and that did nothing. The guy at the part store told me to check the tube behind the pressure switch and make sure its clear. I did that and the heat worked all day. Now it doesn't. After several cycles, the LED indicates a lockout. thoughts?
