Answers to Common Questions
View All FAQsWhat 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 or the circuit is miswired. Other causes include a stuck internal contact, reversed line/load on the switch, incorrect 3‑way traveler connections, or a fixture wired to constant power. Smart bulbs or smart switches left in “always on” can also bypass control. If you notice buzzing, heat, or sparks at the switch, turn the breaker off and schedule service. We handle troubleshooting in areas like Lakewood, NJ.

Panel replacement cost is set after an on-site evaluation. Pricing depends on panel amperage (we specialize in 200‑amp installations), the condition of wiring and grounding, required code upgrades, and whether a full service upgrade is needed. You’ll receive a free, transparent estimate before any work begins with no surprise fees. Our licensed electricians handle permits, coordinate with your utility, and complete inspection and testing for safety. 24/7 scheduling is available across Central NJ, including Toms River.

Yes, you can replace a simple light switch if you fully turn off the breaker and match the wiring like‑for‑like. However, shock and arc risks are real, and code issues can arise. Guaranteed Service provides licensed, code‑compliant switch repairs with free estimates, same‑day/24‑7 help, and a satisfaction guarantee in towns like Toms River.
Quick checks:
- Turn off the correct breaker.
- Verify power is off at the switch.
- Label wires and replace with the same type.
- Stop if wires are damaged or breakers trip.
