What causes a light switch to stop working but light stays on?

A light that stays on while the switch does nothing usually means the switch failed closed or the circuit was miswired. Other causes in Englewood homes include a 3-way issue, a smart switch or app override, or line and load tied together. If the switch is warm, buzzes, or smells burnt, turn off the breaker. Fix-it 24/7 performs electrical troubleshooting and repairs, including switch, dimmer, and GFCI work.

• Try the other 3-way switch.
• Check if the fixture has a pull chain.
