Steps

Goal: Confirm the symptom, rule out power and outlet, then isolate the thermal fuse or control board—or call a pro.

  • Turn off power at the circuit breaker before touching the stove. Confirm the oven and cooktop are off.
  • Turn the breaker back on. Try the stove controls—display, lights, burner knobs. If the stove does nothing, proceed to Check power and outlet.

Check power and outlet

Goal: Rule out circuit breaker and outlet before opening the range.

  • Check the circuit breaker. Electric ranges use 240 volts—two breakers tied together or a double-pole breaker; both legs must be on. Gas ranges use 120 volts. Reset the breaker if tripped. If it trips again when you turn the stove on, call a technician.
  • Confirm the range is plugged in firmly. Electric ranges have a four-prong or three-prong 240-volt plug. Gas ranges have a standard 120-volt plug. Test the outlet with another device if the range has a separate receptacle.
  • Check behind the range: electric ranges have a thick cord and no gas line; gas ranges have a gas line and a standard plug. Both need power for the control panel and burners.
  • Good: Power is on and outlet works. Proceed to Thermal fuse path.
  • Bad: Breaker keeps tripping or outlet is dead—call an electrician or technician.

Thermal fuse path

Goal: Test and replace the thermal fuse when power is good but the stove does not respond.

  • Unplug the range and turn off power at the breaker. Open the back panel per your model. Check your owner’s manual or search “[brand] [model] range service manual” for disassembly steps.
  • Locate the thermal fuse (small white or silver cylinder, often near the oven cavity). Test for continuity with a multimeter. No continuity means it has blown—replace with an exact match (match the part number from the old fuse).
  • Reassemble and restore power. The stove should respond if the fuse was the only fault.
  • Good: The stove display and controls work. See Verification.
  • Bad: Thermal fuse is good or replaced but the stove still does nothing—the control board has likely failed. Call a technician.

When to get help

Call 911 if you smell gas—evacuate and call from outside. Do not turn on lights or appliances.

Call an appliance technician if:

  • The circuit breaker trips when you turn the stove on.
  • Power is good but the stove still does nothing (control board).
  • You are not comfortable working with electricity or gas.

Do not work on gas lines yourself.

Verification

  • The stove display or lights turn on when you operate the controls.
  • The stove responds to keypad or knob input.
  • Burners respond when you turn the knobs (electric coils glow or gas igniters click).
  • No tripping breaker or gas odor.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Power off at breaker Turn off the circuit breaker before touching the stove or wiring.
  2. Power and outlet Check circuit breaker, plug, and outlet.
  3. Thermal fuse Test and replace the thermal fuse if blown.
  4. Control board If power and fuse are good, the control board may have failed—call a technician.
  5. Call a pro Breaker trips, gas smell, or control board—call an appliance technician.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Range type (gas or electric)
  • Whether the display or lights ever come on
  • Circuit breaker and outlet status
  • Thermal fuse test result
  • Steps already tried

Does the stove respond at all—display, lights, or hum?

Turn on the breaker and try the stove controls. If nothing happens, the fault is power, thermal fuse, or control board.

Turn on the breaker. Try the stove controls—display, lights, burner knobs. No response: proceed to check power. Display works but burners do not heat: different problem (igniter, infinite switch); see a heating guide.

No response Display works

You can change your answer later.

Different problem — stove responds

Your stove display and controls work. The problem may be heating or another function. See a heating guide (e.g. fix-oven-will-not-heat) or call a technician if the burners do not heat.

Done

Is the circuit breaker on and the outlet working?

Power must reach the range. Electric ranges need 240 volts; gas ranges need 120 volts for controls.

Check the circuit breaker—reset if tripped. Electric ranges use a double-pole breaker; both legs must be on. Confirm the range is plugged in firmly. Test the outlet with another device if possible. Good: breaker and outlet on. Bad: breaker keeps tripping or outlet dead—call a pro.

Yes No

You can change your answer later.

Does the thermal fuse have continuity?

The thermal fuse is a small white or silver cylinder, often near the oven cavity. Test with a multimeter.

Unplug the range and turn off power. Open the back panel per your model. Locate the thermal fuse near the oven cavity. Test for continuity. No continuity: fuse blown—replace with exact match, reassemble, test. Continuity: fuse good—proceed to control board.

Yes (good) No (blown)

You can change your answer later.

Replace thermal fuse and test

Replace the thermal fuse with an exact match (match the part number). Reassemble and restore power. The stove should respond if the fuse was the only fault. If it still does nothing, the control board may have failed—call a technician.

Done

Is the control board the likely cause?

If power and thermal fuse are good, the control board has likely failed.

Power is good and the thermal fuse tests good. The control board has likely failed. Control board replacement is model-specific and often requires a technician. Inspect for burn marks or bulging capacitors—do not attempt to repair. Replace with a matching part or call a technician.
Question

Control board replacement needed?

Done

Call a technician

Call 911 if you smell gas—evacuate and call from outside. Call an appliance technician if the breaker trips when you turn the stove on, power is good but the stove still does nothing (control board), or you are not comfortable working with electricity or gas. Do not work on gas lines yourself.

Frequently asked questions

Why would a stove not turn on at all?
Common causes: tripped circuit breaker, dead outlet, loose plug, blown thermal fuse, or failed control board. Gas ranges also need power for the control panel and igniters—check power first, then the thermal fuse and control board.
Can I fix a stove that will not turn on myself?
Yes, for power checks, outlet testing, and thermal fuse replacement. Turn off power at the breaker first. Control board replacement is possible but often requires a technician. Do not work on gas lines—call a pro.
When should I call a technician for a stove that will not turn on?
Call 911 if you smell gas. Call an appliance technician if the breaker trips when you turn the stove on, power is good but the stove still does nothing (control board), or you are not comfortable working with electricity or gas.
