Tech was out for not cooling. When checking the system seen water in garage. Last visit tech let customer know that we need to clears drain line and add safety switch to drain. Reason why fuse has blown was due to float switch wire had touched emergency drain pan. Causing fuse to pop. Let customer know that we would need to add a safety switch to drain line to prevent flooding from happening. Customer went with option 1 . tech use 3 amp fuse to get system up and running. Check drain line customer has done cleared and cleaned it out. At this time system is operating.
