2AG .5A Slow Blow Glass Fuse for Doorbox Controller - for AC
 

This Fuse is in-series with the AC power cord and the electronics in the Door Box Controller. It should never blow, but if there's no power to the Controller and it's plugged in to a live AC outlet, this might be the problem.
 

The other fuse in the Controller is a fast blow fuse, but you can use this one to replace either one (using the Slow Blow on the Phone Line may prevent Caller ID from working?).
 

This is a Slow Blow Fuse.
 

Unplug the AC before removing the circuit board from the Metal Box!

It's easy to get the circuit board out of the Controller by spreading the legs on the metal box.

The AC Fuse is the top fuse, next to the AC power cord on the circuit board. The Phone LIne Fuse is the bottom  fuse.

You can tell the fuse is Slow Blow by looking for the two little solder blobs on the wire inside the fuse (circled in red).
