Good evening.

I have noticed lately a small problem with my furnace blower. The furnace works fine, keeping at the right temperature. However, when the furnace reaches temperature, it shuts off. An then in a few minutes or so, just the blower will start up, run maybe 30 seconds to a minute and then shut off. It'll do this every cycle of the furnace.

I tried a different thermostat, and it did the same thing. I don't know where else to try.... HELP!

Sounds like your fan limit/control is turning the fan on again to cool down.. You may have to turn the "Off" setting to a lower temp.

Id look at the air filter first is it clean and the AC coil clean if you have one. Then check out the fan control. Its not up in the tstat let that alone. You fan will stay on and run when you go to fan on ???

Ed good call

Dirty filter or dirty coil or dirty blower wheel, but

Sooted up heat exchanger can also cause this.

Dirty burners or low L.P. Gas pressure.
