How to Fix a Cooktop That Won’t Turn On?

By AT Appliance Services Repair

A cooktop that won’t turn on can be a major inconvenience, whether it’s electric or gas. Before calling for a repair, try these troubleshooting steps to get it working again.

1. Check the Power Supply

For electric cooktops, ensure it’s plugged in and receiving power. Test the outlet with another appliance or check your home’s circuit breaker for a tripped switch. Gas cooktops don’t rely on electricity to ignite manually, but if the electric igniter isn’t working, it may be a power issue.

2. Inspect the Control Knobs

Make sure the control knobs are properly aligned and not loose or damaged. Sometimes, knobs can become misaligned, preventing proper contact with the internal switch.

3. Test the Igniter or Burner

For gas cooktops, if the burner isn’t igniting, listen for a clicking sound when turning the knob. If there’s no click, the igniter may be faulty or clogged with food debris. Clean the igniter with a soft brush and try again.

4. Examine the Surface Burners

For electric cooktops, a faulty burner element may be the problem. If one burner isn’t working, try swapping it with another of the same size. If the replacement burner works, the original one needs to be replaced.

5. Inspect the Wiring and Fuses

Some cooktops have internal fuses or wiring connections that can fail over time. If you’re comfortable doing so, check for loose or damaged wires beneath the cooktop. If a fuse has blown, replace it with the correct type.

6. Test the Infinite Switch

The infinite switch controls the power level for electric burners. If a burner isn’t heating properly, a faulty switch could be the cause. A multimeter test can confirm whether it needs replacement.
