Wired doorbell pro.
Doorbell works great except when someone rings the doorbell….
Replaced the transformer from 24VAC 20VA to a 24VAC 40VA and still had the same issue.
Doorbell normally pulls 0.05 amps and is getting 25VAC. but when it is rung, the current spikes up to 2.3 amps and then goes back down to 0.05 amps. Now the voltage is 6VAC and it stops working.
Anyone else have a similar issue or know how to fix it? Customer support is useless. I can’t even count how many times I have restarted and re-setup the doorbell.
