SOURCE: have an older Trane furnace. no 'board' just

If you do not have a fan board you have a fan limit switch. That brings the fan on about 120 and off at 90. It is located in the middle of your heat exchanger. Check across with voltmeter when you turn it on. If you have voltage after it runs for a while its bad. Or just jumper across it and see if afan comes on. They just go bad. Pick one up at HVAC supply house or you can order on line. If you have an electronic thermostat. On the back it has a switch that says gas or el switch to electric and the fan will come on with furnace. Rus but you still need to change fan limit this will just get you thru till you get it.

Chances are you need to replace both the condenser and furnace, then you you should get a varaible speed blower with the new furnace, get at least a 90% gas system with a 16 SEER condenser, save on energy cost as soon as it's installed. Go Get IT

Trane XB80, no heating, limit circuit open


Sometimes these can be reset by gently taping them on the floor. Can be caused by not changing your furnace filter.

Trane ac, inside blower does not stop. The heater stops, the Ac compressor stops, but the inside blower does not, this the thermostat set at auto. Regards, Faylbp


Hi, I want you to try a couple of things for me if you will. Go to the thermostat and remove the cover. Now if you have a small bladed screw driver, loosen all the screw on this next section and remove it. Turn off power to the unit, if it is a split system, turn off the indoor unit. Once you remove this section which is the thermostat you will see the subbase and wiring. Take the red wire loose and off of the terminal. You may have a red jumper wire going from RH to RC. Remove the red wire coming into the stat at either point. Give it a minute and see if the fan stops now. If it does, you will need to replace the stat. If not, depending on the age of your unit, if your high limit/fan control tripped, that will be the problem. Some units have a fan control combination high limit that trips causing the fan to run all the time. You need to take a look at your heater section at the front of it to see what kind you have. If it is a combination fan/limit. it will be inserted into the fire box. It is square looking box with a cover on it some with a auto/ manual button on them Sometimes the contats will stick causing the fan to run. They can be removed with power off and cleaned up. They will have a dial with a temperature reading on them which tells the fan to come on when it reaches this set-point and off when it cools down. It may have stuck closed. Check what I have told you with the stat, and this and let me know the age of heater and if it is a split system Trane with a remote condenser and furnace located somewhere else. Get back to me on this.
