I recently charged my AC System and now blowing fuse that runs the fan,AC,digitial dash. Did I overcharge the AC system? All was working fine before.
" Did I overcharge the AC system?"
No. The compressor clutch does not care about how much or how little freon is in the system. It’s mechanically driven…The electrical load does not change with the compressor load.
Unless you have some sort of short in the wiring to the pressure sense switch or the wiring to the clutch, this is completely unrelated to the Freon added.
I would measure the current flowing to the clutch coil. Maybe you have a problem there. You wouldn’t have seen it before because the low refrigerant pressure kept the clutch from being engaged, or being engaged for very long.
