How can someone tell if an ac relay fuse is blown?

There are a few ways to tell if an AC relay fuse is blown:

1. Visual inspection: The fuse will often have a small window that allows you to see the filament inside. If the filament is broken, the fuse is blown.

2. Continuity test: You can use a multimeter to test the continuity of the fuse. If the multimeter does not beep when you touch the probes to the terminals of the fuse, the fuse is blown.

3. Voltage test: You can use a voltmeter to test the voltage across the terminals of the fuse. If there is no voltage, the fuse is blown.

If you suspect that an AC relay fuse is blown, it is important to replace it as soon as possible. A blown fuse can prevent the air conditioner from working properly, and it can also be a fire hazard.
