I have a Payne furnace that the fan will not shut off automatically

This answer was rated:

I have a Payne furnace that the fan will not shut off automatically or manually. It continues to run unless I unplug the unit.
Can you help?
Hello,

there is one easy test to decide what is wrong if you dont mind unhooking one wire in the furnace?

Customer: replied 3 years ago.

I will be glad to give it a try

Renove the doors from furnace.
Locate where the thermostat wires attach in the furnace.

The wire we are after is on G terminal.

Remove that wire and turn power back on.

If blower continues = bad circuit board with stuck relay.
If blower stops = bad thermostat or short in thermostat wire.

Terminal was labeled GC. Disconnected, replaced cover, and plugged back in and fan began to blow again.
