First off let me say I’m not entirely sure if this is the sub I should be posting in, feel free to correct me or direct me to the correct one, thanks!

So this is the second house I’ve had this doorbell on and everything has been working fine up until last week. All of a sudden we noticed no lights were on the doorbell. FIL came by to do some work, said the GFCI was tripped in the bathroom, the same circuit that the doorbell is wired to, it’s currently back up and running but not the doorbell. Also the power module that was hooked up to the chime box was super hot, not sure if that’s normal but I removed it just in case. So i’m not sure what is going on here, very strange, it’s like the contacts that run to the doorbell all of a sudden stopped working or something. I pulled the doorbell off and plugged it in via the USB port and it was blinking red for a few and is now solid green, so I’m assuming it’s not fried or completely dead. Any ideas what could be happening?Should I buy a new power module? Thanks!
