Oven Won’t Turn On — Electric or Gas: What Homeowners Should Do
When your oven refuses to turn on, it disrupts your daily routine — whether you're preparing dinner for the family or baking during the holidays. This issue is one of the most common reasons homeowners in San Diego call for appliance repair. Ovens, especially gas models, have several interconnected components, and a single faulty part can prevent the entire unit from powering up, heating, or even responding to controls.
Understanding the possible causes can help you take the right steps before scheduling a repair. Below, we break down the most frequent reasons a gas or electric oven won’t turn on, common symptoms, and helpful troubleshooting tips.
1. Power Supply Problems — The First Thing You Should Check
Before assuming the oven is broken, check its power source. This is a frequent issue in older San Diego homes where circuits may overload easily.
For Electric Ovens:
Electric ovens require a dedicated 240-volt connection. If the breaker trips, the oven may appear completely dead.
What to check:
– Look at your electrical panel for a tripped breaker
– Make sure the oven’s plug is firmly inserted
– Inspect the outlet for burn marks or loose wiring
A partially tripped breaker may allow some functions, such as lights or display, but prevent the heating element from working.
For Gas Ovens:
Gas ovens still rely on electricity to power the igniter and control board. If you have no display, no clicking sound, and no interior light, electricity may be the issue — not the gas line.
2. Faulty Igniter — The Most Common Cause for Gas Ovens
In gas ovens, the igniter heats up and signals the gas valve to open. When the igniter becomes weak or faulty, the oven won’t light even if the stove burners are working.
Signs of a bad igniter:
– No glowing from the igniter
– Clicking without ignition
– Gas smell followed by no flame
– Oven takes too long to heat
San Diego’s coastal moisture can accelerate wear on gas components, leading to corrosion and slower ignition response.
What you can do:
– Look through the bottom panel to see if the igniter glows
– If it glows dimly or not at all, it likely needs replacement
Igniter replacement is a common service and typically resolves the issue.
3. Broken Heating Element in Electric Ovens
If an electric oven won’t turn on or heat up, the bake or broil element may be burnt out.
How to identify a faulty element:
– Visible blistering or cracks
– No glowing red when heating
– Oven warms slightly but never reaches temperature
If the oven light and display work but the temperature stays low, the element is almost always the culprit.
4. Defective Temperature Sensor
Both gas and electric ovens rely on a temperature sensor to regulate the heating cycle. If the sensor fails, the control board may block the oven from turning on.
Common symptoms include:
– overheating
– underheating
– oven shutting off shortly after turning on
– inaccurate temperature readings
In San Diego’s hotter inland areas, heat exposure behind kitchen cabinetry can affect sensor performance over time.
Basic test:
Gently check whether the sensor is touching the oven wall. If it is bent or pressed against metal, it may misread temperature.
5. Control Board Failure — A Frequent Issue in Modern Ovens
Newer ovens contain digital control boards that manage all functions. If the board fails, the oven may lose power, fail to heat, or respond erratically.
Signs of a faulty control board:
– buttons not responding
– error codes
– flickering display
– oven shuts off mid-cycle
– no sound or light
Electrical surges and worn relays are the most common causes. Repairs usually involve replacing the board.
6. Gas Supply Problems (For Gas Ovens)
If your gas oven won’t turn on and you do not smell gas, the supply may be blocked:
Possible reasons:
– closed gas valve
– kinked or damaged gas line
– clogged burner jets
– malfunctioning gas safety valve
Homeowners near coastal San Diego communities sometimes experience corrosion in gas fittings, contributing to ignition issues.
Quick checks:
– Ensure the gas shutoff valve is fully open
– Try turning on a stovetop burner to confirm gas supply
If burners work but the oven doesn’t ignite, the issue is likely with the igniter or valve — not the gas line.
7. Blown Thermal Fuse
Many ovens include a thermal fuse that shuts the appliance down if it overheats. Once the fuse blows, the oven will not turn on at all.
Causes:
– blocked airflow
– failed cooling fan
– self-cleaning cycle overheating
– improper ventilation around cabinets
Replacing the fuse is a simple repair, but the cause of overheating must also be identified.
Troubleshooting Checklist Before Calling a Technician
Here’s what homeowners can safely check on their own:
✓ Confirm the breaker is not tripped
✓ Ensure the oven is plugged in and receiving power
✓ Check that the gas valve is open (gas ovens)
✓ Look for visible damage on heating elements
✓ Listen for the igniter clicking
✓ Test the stovetop burners to confirm gas supply
✓ Reset the oven (most models have a reset option)
If your oven still doesn’t turn on, a technician should diagnose the internal components.
When to Call a Professional Appliance Repair Technician
You should schedule oven repair if:
– the igniter does not glow
– the oven produces no heat
– the breaker keeps tripping
– the oven shuts off during preheat
– you smell gas
– there are error codes
– none of the controls respond
– your self-cleaning cycle caused a shutdown
Gas ovens in particular require expert diagnostics — attempting DIY repairs can be dangerous.
A professional technician can test electrical continuity, inspect the gas system, check sensors, and replace worn components safely and efficiently.
