how to replace doorbell transformer

Replacing a doorbell transformer is not as complicated as it sounds. In fact, it is a relatively easy home improvement project that most do-it-yourselfers can complete in an afternoon. The first step is to turn off the power for safety. Typically, this is done at the circuit breaker panel. Once the power is shut off, use a screwdriver to open up the transformer cover. A Phillips head screwdriver will usually be all you need in order to loosen and remove the screws that hold the cover in place.

Now that the cover is removed, you’ll need to disconnect the wires from the transformer. Be sure to take a picture of how the wires are connected before proceeding. This will make it easier to connect them again later when replacing the transformer. With the wires disconnected, unscrew the transformer and then slide it out of its housing. Now you are ready to attach the new transformer.

Attach the new transformer back into its housing, being sure to follow the instructions on the packaging. Next, reattach the wires as you had them before, and then screw the transformer into place. Be sure to match the wattage and voltage numbers from the old transformer with the new one in order to ensure that the correct amount of power is being supplied. Finally, if all has gone according to plan, reassemble the cover plate, and then turn the power back on. You should now be able to ring your doorbell with ease.
