Transformer For Doorbell Is Hot
Va is volt amps or volts times amps or wattage.
Transformer for doorbell is hot. It should tell you either the wattage or the va it uses. Leave the doorbell alone for a bit. The diminished volume can indicate that the transformer you are using doesn t have enough power.
It s perfectly appropriate that her aud model transformer was warm because wherever there is electricity there s also heat like where there s smoke there s fire and thunder and lightning and other dualities in life. I ve tried a variety of 24v transformers including plug in ones rated for 8va 30va the tri volt one on both 16v 10va and 24v 20va posts and am getting tired of returning re buying duds. 12 volts x 1 6 amps equals 19 2va 24 volts x 83 amps equals 20va.
When i took everything apart the first thing i noticed was that the transformer was very hot. There is no polarity on a db transformer primary coil but the secondary will blow like. If you are uncomfortable reading wiring diagrams hooking up wires or soldering them in place consult an electrician for assistance or use the built in rechargeable battery to power your video doorbell.
Also the door bell button was a closed shorted circuit like it was permanently pressed down and the doorbell chime was a closed shorted circuit. After a few minutes check to see if the transformer has a raised temperature. Ordered and collected 30 mins later.
I was about to order a 3rd transformer online when i seen screwfix offering this product. Doorbell pro wired up and works fine but seems to kill the transformers after anywhere from 1 to 5 days. Rated 5 out of 5 by rpltrading from it works having tried 2 transformers over the last 2 weeks from online market places priced at double the price they did not work and both failed to power up my doorbell.
If you have only 1 transformer then there will be. The first wire on the buzzer is the switched hot from a door bell button. Also upon closer inspection the doorbell chime showed some melting in some places.
