I have a front and back doorbell that share a chime. Per instructions, i connected the fuse wire to the post marked “front” after disconnecting the wire from the post marked “front”. I then connected the other end of the fuse wire to the post marked “trans,”
Doorbell running really hot at night, ambient temp is 75F. I disconnected the doorbell and measured voltage from the doorbell wires, 22.5 volts. Within spec. I then measured amperage which of course lets current pass. With no load, not great for my transformer but it was a very brief measurement. When i touched the doorbell wires with multimeter leads, my old doorbell chimes… chimed.
Since i had disconnected the wire from the post marked “front” in the chime box, shouldn’t it have not chimed?
I’m exploring the overheating issue separately but curious about my doorbell engaging Old chimes when i thought it couldn’t.
