Tech was out for no cooling. Found system not coming on. Checked voltage found light switch to furnace bad. Checked and found light switch broken with wire detached. Hooked wire back up for testing. Checked system found capacitor failing. Please note that with the capacitor failing it is causing the blower to overwork , over heat and over amp. This will also cause premature failure to the blower. No safety switch on evaporator coil. On condenser low voltage was bear at any time the wire will touch will cause a fuse to blow. Contactor is pitted and making loud noise. Spoke with customer about repairs that needed to be done. Customer stated that they will change out the light switch as well as capacitor. Customer declined other repairs expected for contactor and low voltage wire. Tech made repairs checked work before leaving. At this time system is operating.
