Hi everyone. I was hoping someone could give me a few pointers. I came home to a hot house yesterday so I opened the ac unit in the garage to take a look. It was nice and cold in there but the fan was not running. I switched the fan to "on" on the thermostat and it still won’t turn on. Could this be as simple as a fuse or something? How would I check? Thanks for the patience. I know nothing about AC systems.
