my xe90 wont stay lit its flashing 4 what does this mean is it getting gas?
I believe Trane puts a label on one of there cover panels that has the codes listed on the sticker.
I think it means ignition lockout.
Over heat lock out.
yes, if the xe80 is the same as the xe90 then 4 flashes is "high-limit switch open".
And now you know everything I know about it.
