Can I replace AC capacitor myself?

Anyone is free to write down the capacitor size for their system, buy another one online, and install it. However, we recommend not doing that. Capacitors can be dangerous. Even after you disconnect the power to the AC, the capacitor still holds a lot of charge.

How do I know if my AC fuse is blown?

If there is the voltage on the “line” side, test for voltage on the “load” side of the fuses by placing the meter's leads on the load wire lugs. If you read voltage on this side(220-240V), this means the current is flowing through the fuse. If you get a zero-voltage reading on the load, this means your fuse is blown.
