Yesterday when I fired up my a/c nothing happened. Found it had blown a 3 amp fuse on the circuit board. Replaced it and blew right away. Hunted like mad for a short. After being inside and out at the unit I found a mouse had chewed the T-stat wire to the outside unit inside the 10" block wall. Pulled it out and taped it up so the wires were not shorting and it runs like a champ now. Needed it today especially as it is 84 and humid as hell.
Boy that was lucky that you found the short. Wow!
Lucky that there was a control fuse. That fuse saves the transformer from cooking up nice and crispy.
I had the same thing happen, but it was a short from a staple that cut into the low voltage wire going out to the condensing unit.
The DD's X was insulating the cellar wall, and he fired a staple from the staple gun with a Non Insulated staples. Well one of them cut in to the wires and shorted it.
DD gives me a call at work, and said Dad,"There is no A/C and the house smells funny. LOL.... It cooked the 24Volt Transformer crispy. LOL
It was easier to run a new wire, than remove the insulation to find the short and possibly more just waiting to happen.
The maintenance on the A/c systems is on the agenda for this week.
The bedroom is a split Fujitsu System .... that one is easy, but the main area is a split overhead, with the dang air handler in the attic. No standing either. It's a pain crawling on the old rotted knees; and even with knee pads. Grrrrrrrr!!
