TROUBLESHOOTING
Chime does not sound:
• Check Circuit Breaker to Transformer: Reset circuit breaker if tripped.
• Reset Chime: Press Reset button located on front of chime base (see Figure 3).
• Check Chime: Disconnect wire from terminal marked “TRANS”. Have someone operate push but-
ton at front door while you momentarily touch the “TRANS” wire to terminal marked “FRONT”. You
will see a small spark if push button, wiring, and transformer are operating properly. Repeat the
steps for “REAR” terminal and rear push button. If wiring between transformer and push button(s)
check out properly, replace chime.
• Check Push Button(s): Remove suspected unit from door frame, disconnect wire from terminals
and touch bare wires together. If chime operates, push button is defective. Replace push button.
• Check Transformer: Momentarily touch the two low-voltage terminals with a screwdriver. You will
see a small spark if transformer is operating properly. If no spark is evident, replace transformer.
Chime sounds but does not complete the tune:
• Check Diode on Front Door Push Button: Verify diode is attached securely to push button (see
Figure 4). If tune still does not sound completely, replace diode.
