Performed diagnostic el darrado hills. 11yr old Lennox split system. Found system on garage side of house not functioning correctly, outside turning on blower not running fan inside. Checked blower capacitor found it just out of range. 5@4.7 good till 4.75... next adjusted the molex connection, on board and system turned on. If problem is loose molex we might need to replace board in near future. Tested system 3 times working for now. Inside of Blower compartment very dusty. Recommend upgrading filtration. Once got system up and running, ran system to perform tune up. Noticed return is kinked over gas pipe. Outside unit partially buried in leafs and debris... need to keep up on regular maintenance on system. System doesn’t have a hard start kit or compressor saver kit. Disconnect ok, contactor ok. Dual capacitor rusting, but holding for now. Had to give system a good bath. Tested other side, inside is louder. Smaller return grill. Removed a lot of leafs and debris again. Have
