Refer to these steps to test the doorbell transformer: Take a multimeter and set it up to test for AC (alternating current) voltage. Make sure the multimeter is set to a minimum of 24 volts. Now connect the tester probes to the low-voltage screw terminals on the transformer.A2. Yes, you can use a multimeter to test the doorbell wires. Set the multimeter to the AC voltage setting and connect the leads to the exposed ends of the wires. If the multimeter reads a voltage of 12-24 volts, it indicates that the wires have power. Q3. What should I do if the doorbell transformer is damaged?4. Loosen the screws or bolt that hold the transformer to the junction box. After disconnecting the wires on either side of the transformer, check to see how it’s secured to the junction box. If there are screws, grab your screwdriver and remove them. If there’s a bolt, turn it counterclockwise with a wrench.

Use a multimeter to check your doorbell transformer. A doorbell or buzzer works on 10 volts, and chimes work on 16 volts. A doorbell transformer changes your standard household voltage of 120 volts to either one of the voltages needed.
