If no cool or heat, just fan on, there has blower start in furnace;
While in air conditioner, regardless fan on or auto, there will be no indoor blower on at all;
While outside condenser and its fan seems fine.
I lready jump wires G, RC and Y in T-start, won't see any difference.
By the way, yesterday it suddentely worked for a minutes or 2 before it is completely dead after I lower the temprature.
Thanks for your advice
Roy
