I have a Amana single split AC 3 ton. For some reason the FAN ONLY function does not work, everything else work fine. I did the following test:
I removed the T-stat cover. jumped R,G,Y 3 wires, condenser started, furnace blower also started. If I only jump R and G, the blower will not work , condenser will not work either. I remember I jumped R and G before, the blower started right away, but now, the blower does not work anymore. What can cause this problem ? Thanks.
