hello, name is walt, having some cooling problems wit a trane heating unit outside wherein the cooling fan has stopped working, i patched it up wit another one, work for a day or so and now the newer one is having problems. to make matters worse, i think the whole unit is starting to overheat now, have since turned the thing off but can't go long without ac wit kids around. have to do this on my own since finances are already tight, would greatly appreciate some greatly needed advice, thanks a million. walt

If your unit is overheating I would suggest that you call a licensed repair person to come and properly service your unit. You may or may not have made things worse by trying to fix it yourself. Please do not keep running the unit as you could do more harm to the unit and possibly start a fire by the wiring heating up too much. Get the fans out and use them in the meantime.
