Your wiring concerns may be more with the thermostat wiring connections than the condensor connections. if you look inside the cover of the evaporator unit (usually called air handler) there should be a wiring diagram glued to the panel cover. This diagram will show all 3 units (stat,cndsr, airhndlr) and the wiring needed between them. Trane and Lennox are notorious for having the most wiring between components. You also need to be sure the stat is the correct type for the system (i assume this is a heat pump system) and there can be as many as 9 wires from stat to system and 6 wires from inside to outside units. Also, the stat will have a wiring diagram with it that shows most typical system wiring including the wiring between in and out units. Your best bet (if you have no diagram on the unit or with the stat) is to call trane and have their tech division fax a diagram to you. Goodluck,Macgivor

SOURCE: furnace doesn't heat the burners
The flame sensor is not sensing that the flame has come on....the flame sensor could be dirty or the could be ignition module problems...
I am assuming that this is not a new installation....because reveres polarity can cause that also....
I would clean/ replace the flame sensor first and then from the the control board will ned to be replaced if that don't work.....
Have had to drive a totally separate ground rod and ground the furnace separately in one extreme case...
