Frequently Asked Questions
1. What is a continuity tester used for in appliance repair?
A continuity tester checks whether electricity can flow through a component or circuit. Technicians use it to diagnose failed switches, fuses, heating elements, wiring, and other electrical components.
2. Can a continuity tester replace a multimeter?
A continuity tester is excellent for quickly verifying electrical paths, but a multimeter provides additional measurements such as voltage, resistance, and current. Many technicians use both tools.
3. How do I know if a component has continuity?
If the tester produces an audible tone, visual indicator, or positive reading when probes are connected across the component, continuity is present. If no indication occurs, the component may be open or failed.
