My upstairs unit located in the attic, has a problem where the blower fan starts the stops it does this several times before it stays started. Going in the attic I can hear a relay engage, the blowere will kick over once and I hear the relay disengage. This happens several times before the blower fan will stay on. Also while the a/c is running the blower will stop and the start/stop cycle will start again. I replaced a 7.5mfd/370vac capacitor on the blower, but it did not resolve the issue.

It sounds like its the fan relay thats causing you your grief. You may have to replace the control module to solve the problem.

No matter how idiot proof you make something better idiots will always try and screw around with it!
