We had a Ring doorbell pro. We bought the specified hardwire plug in power supply to hardwire it because our existing doorbell circuit was unuseable.
All went well for a couple months then the doorbell kept loosing wifi & got super hot. Okay, stuff happens so now we have a brand new Ring doorbell 3 to replace it. The power supply for the pro will not work for the 3- confirmed yesterday by customer support. Fine.
Then I started going through the community posts. Finding a post about HOT doorbells-the power supply hardwired for several models of Ring doorbells needs a wirewound resistor installed in line from transformer to doorbell! NO WHERE in the instructions that came with the doorbell is this mentioned! Why wasn’t this mentioned when i bought the doorbell pro power supply directly from Ring was this mentioned? Yeah it has a diode inside just for this doorbell but oviously no resistor. Try & find the resistor in the online store- if it wasn’t for a reply to a previous post I would have never known!
So the doorbell pro is powerless (unplugged) until I can replace it with the doorbell 3 AFTER I receive the wirewound resistor needed for the hardwire power source. I’m pretty sure the doorbell pro is damaged.
My main gripe beyond the $$ and time this has cost us is WHY is this resistor not mentioned in any instructions that came with the unit? Either unit!! Thankfully I did my own research before the new one was “plugged in”. WOW Ring- you really need to provide better info on these things. Show this item in your online list of sale items too with details. I wonder how many other people have had this same problem. Shameful.
