An oven that won’t start usually points to power, controls, gas flow, or a failed igniter—check these in order.
Quick Safety And Set-Up Checks
Start with safety. If you smell gas, leave the area and call local emergency services from outside. For electric models, cut power at the breaker before removing panels. Wear gloves and eye protection when handling sharp panels or glass, carefully.
Next, confirm model type and fuel: electric or gas. Note any error codes on the display.
Causes For An Oven Not Turning On — And The Fix Order
Work through the common issues from fast checks to part tests. Many no-start cases come down to control settings, a tripped breaker, a weak igniter, or a failed bake element.
| Issue | What To Check | Tools |
|---|---|---|
| No power | Breaker, outlet voltage, cord seating | Multimeter |
| Wrong settings | Bake/Broil mode, temp set, press Start | None |
| Control lock / delay | Child lock icon, delayed start, Sabbath | User manual |
| Door latch engaged | Latch jam after self-clean, door switch | Screwdriver |
| Failed bake element | Visible breaks, continuity test | Multimeter |
| Weak igniter | Glows but no flame, amp draw low | Clamp meter |
| Gas off | Shutoff valve open, supply line kink | Wrench |
| Blown thermal fuse | No display after self-clean, open fuse | Multimeter |
| Bad sensor (RTD) | Ohms near 1080Ω at 70°F, wiring | Multimeter |
| Control board fault | No output to element/igniter | Multimeter |
Power And Control Basics
Check the breaker first. Ranges draw heavy current, and a partially tripped two-pole breaker can feed lights and clock while the heating circuit stays dead. Switch it fully off, wait ten seconds, then switch it on. Reseat the plug on freestanding units. If the outlet is suspect, test voltage with a meter.
On models with touch panels, confirm you actually started a cycle. Pick Bake, set a target temperature, then press Start. Some brands also need a separate confirmation for preheat. If the knobs were removed for cleaning, place them back in the right positions so the shaft flats line up.
When The Timer Or Lock Blocks Heat
Lockouts and timed modes can stop heat. Look for a padlock or “Sab” on the display. Turn off child lock with the brand’s key combo, then clear any delay start so the unit fires now, not later. If the door latch stuck during self-clean, move the lever to the unlocked side with the power off. A misread door switch can also block the relay, so listen for a soft click as the door shuts.
Electric Models: Element And Sensor Checks
Cut power. Pull the range forward and remove the rear cover. Unplug the two wires to the lower bake element. Measure resistance; a typical 240 V element reads between 10–40 Ω. Open circuit means the element failed. Inspect for blisters or cracks along the calrod.
Next, test the temperature sensor, also called the RTD. At room temperature near 70°F, the sensor should read around 1080 Ω across its connector. A shorted or open sensor can block heat or trigger errors. Follow the harness to the control and look for cooked spots or loose spades.
If both parts test good, check for voltage leaving the control board during a Bake call. With the unit powered and a cycle started, a meter should show output to the bake terminals. No output points to a failed relay or board trace. Power down before moving any wires.
Gas Models: Igniter, Gas Flow, And Flame Sense
Open the oven, remove the bottom panel, and watch the glow bar while calling for Bake. A healthy igniter reaches full brightness and draws the current needed to open the safety valve. A weak unit may glow for minutes with no flame. Replace if the amp draw is below spec or if it never reaches full glow.
Confirm the manual shutoff valve is open. The handle should be parallel with the pipe. Check that the supply line isn’t crushed as the range slides back. If the burner lights briefly then drops out, clean the burner ports and check flame sense routing. Do not spray cleaners on the igniter.
If you smell gas, stop work and get everyone out. Call emergency services or your gas provider from outside. Do not cycle switches or use phones inside near a suspected leak.
Brand Guidance And Reliable References
For step-by-step brand tips, manufacturer support pages are handy. See GE’s guide to ovens that will not power on and basic resets. For leak response rules and contact steps, use your state energy or utility page for directions you can follow right away.

Step-By-Step: Fast Checks In Under 10 Minutes
1) Breaker Reset
Flip the range breaker fully off, pause, then back on. Many users report instant recovery after a nuisance trip.
2) Control Confirmation
Select Bake, set a temperature, and press Start. Try a second mode like Broil to see if any heat path works.
3) Door And Latch
Cycle the door. If the latch feels stiff after a recent clean cycle, unlock it with power off. Check for a click at close.
4) Gas Valve Position
On a gas unit, turn the shutoff handle parallel with the pipe. Relight surface burners to confirm supply.
Deeper Checks: Tools And Readings
Element Continuity
With wires removed, measure resistance end-to-end. Any reading in range points to continuity. Open line calls for a new element.
Igniter Current
Clamp around one igniter lead. Many flat igniters need around 3.2–3.6 amps to open the valve; round styles often need less. If the draw is low, replace the igniter even if it glows.
Sensor Ohms
Room-temp sensors read near 1080 Ω. Heat applied with a hair dryer should raise resistance smoothly without jumps.
Board Output
During a Bake call, check for output to the bake terminals. If line voltage never appears and wiring is intact, the relay or board has failed.
After A Self-Clean Cycle That Left The Oven Dead
Self-clean runs hot. The thermal fuse can blow, killing power to the control. If the display is blank and buttons do nothing, test the high-limit fuse for continuity and inspect the harness near the vent. Replace any cooked connectors and address cooling airflow so it doesn’t repeat.
When Heat Starts Then Stops
If preheat begins then stalls, try Broil. Broil works while Bake does not usually points to the lower element or the bake igniter on gas. If both drop out, suspect a sensor fault, board issue, or a supply problem. Look for error beeps or codes on the display.
Parts And Symptoms At A Glance
| Part | Typical Symptom | Next Step |
|---|---|---|
| Bake element | No heat in Bake, Broil OK | Continuity test; inspect calrod |
| Broil element | No heat in Broil, Bake OK | Continuity test |
| Igniter | Glows with no flame | Measure amps; replace if low |
| Safety valve | Igniter hot, no gas flow | Pro diagnosis; replace if failed |
| Thermal fuse | Blank display, no response | Check continuity; replace |
| RTD sensor | Erratic temps or shutdowns | Ohm test; inspect wiring |
| Door switch | Light works but heat blocked | Switch click test; meter |
| Control board | No output to load | Meter live outputs |
Smart Tips To Avoid Repeat Failures
Keep Vents Clear
Pull the range out twice a year and clear dust from rear vents and the bottom drawer area. Better airflow spares relays and fuses.
Skip Marathon Self-Cleans
Use shorter cycles or manual cleaning for heavy spills. Long clean runs drive heat into the control bay.
Check Slide-In Clearance
As the unit slides back, make sure the gas line or cord doesn’t pinch. A kinked line or loose plug invites a no-heat call later.
When To Call A Technician
Call a pro if you measure live voltage at the control with no output, if the gas valve never opens with a strong igniter, or if wiring shows heat damage. Licensed techs can test live circuits safely and confirm part numbers by model and serial.
Simple Replacement Roadmap
Bake Element
Remove the rear cover, disconnect two spades, pull the element forward from inside the cavity, and slide the new one in. Secure with the two screws and reconnect the wires one-to-one.
Flat Igniter
Shut off gas and power. Lift the bottom panel, remove the flame spreader, and unbolt the igniter from the burner tube. Route the new harness away from flame, then restore gas and power and test.
Sensor Probe
Inside the cavity, remove two screws at the rear, ease the probe forward, swap the connector, and reinstall. Keep the wire insulation intact where it passes the liner.
Final Check Before You Reinstall
Run Bake and watch for steady preheat. Verify the door gasket seals and the fan hum is clean. Slide the unit back while watching the cord and gas line. Level the feet so pans sit flat.
Troubleshooting Cheat Sheet By Symptom
No lights or beeps: treat it as a supply fault. Check the outlet with a lamp, then the two-pole breaker, then the thermal fuse behind the rear panel on some models.
Clock works but no heat: look at control settings first, then the bake element on electric, or the igniter on gas. Try Broil to see if a second heat path still works.
Gas burners work, oven dead: that narrows it to the bake circuit. Watch the glow bar and measure current draw. If the glow never reaches spec, replace the igniter.
After a move or remodel: cords, gas lines, and harness plugs get tugged during installs. Pull the range forward, reseat connectors, and confirm the gas valve is parallel with the pipe.
