Doorbell Not Working – Does Not Ring or Buzz If you find one (or more), strip the insulation from the wire ends and splice them with a short piece of matching wire, using properly sized wire nuts. Look for any breaks in the doorbell wiring. If the new reading still doesn’t match the voltage marked on the transformer or bell, replace the transformer.ģ Check the wiring. But this time, set the meter’s voltage range to a slightly lower value. If the reading is close to the proper secondary voltage, test again. If the reading is significantly higher than the correct secondary voltage, replace the transformer. If the transformer is working correctly, the meter’s reading should be 12 volts or the secondary voltage marked on the transformer or bell.

Set the meter’s voltage range to 120 volts AC and touch the meter’s probes to the two low-voltage terminal screws on the transformer (the ones with the small-gauge bell wire). Use a volt-ohm meter to test whether the transformer is working. However, be aware that even the low-voltage side of an electrical circuit like this could carry dangerous current if the transformer has failed, though this is fairly rare. The doorbell button and the small-gauge wires that run from the button to the doorbell and transformer are normally safe to work on without shutting off the power. Wire nuts connect standard-voltage wires to the transformer. MastechĪ conventional doorbell has low-voltage wires that connect the chimes or bell to the transformer and button, which acts as a switch. Have retail experience?
