Did you ever figure out what the problem was? I am having the same problem and the limit switches are OK?
Four flashes is supposed to mean bad limit switches. I replace both and the problem continues. It runs about 5 min then the gas is turned off and the fan continues to run and I get the 4 flash code?...
My 8 year old Trane XE80 heat comes on then when it cycles off the fan keeps running and I get 4 flash error code. Help please. Thanks
