5 Signs Your Oven, Stove, or Cooktop Needs Repair
KitchenA working stove and oven are the backbone of a functioning kitchen, and when something goes wrong, dinner plans go with it. Whether you're running a gas range, an electric cooktop, or a glass-top induction unit, these appliances rely on a mix of heating elements, igniters, thermostats, and increasingly complex electronic controls — meaning there's more than one way for things to go wrong.
The most obvious red flag is an oven that won't heat, or heats unevenly, leaving half your casserole burnt and the other half raw. This is often caused by a failing bake or broil element, a faulty temperature sensor, or a control board that's no longer regulating heat correctly. On gas models, a burner that won't ignite — or clicks endlessly without lighting — usually points to a dirty or damaged igniter, which is a quick fix once diagnosed correctly.
Glass and ceramic cooktops bring their own set of concerns. Cracks in the glass surface are a safety hazard and should never be ignored, since they can expose wiring or cause the surface to fail entirely under heat. Discoloration, uneven heating zones, or a cooktop that won't power on at all typically point to damaged heating coils beneath the surface or a wiring issue in the control module — not something to troubleshoot with a screwdriver and a YouTube video.
Temperature sensor issues are sneaky because they don't always announce themselves clearly. Your oven might seem to work fine, but your food consistently comes out undercooked or overcooked despite following the recipe exactly. A quick calibration check and sensor test from a technician can usually resolve this without needing a full part replacement.
Our technicians at Aerotech Solution work on both gas and electric models across all major brands, using precision diagnostics to pinpoint the actual point of failure rather than guessing and swapping parts. We carry common replacement parts for burners, igniters, sensors, and control boards, and can source model-specific components after diagnosis. Don't let a faulty stove derail your kitchen — if you're noticing any of these five signs, schedule a repair before a minor issue turns into a bigger, more expensive one.
Common Causes
Ranges combine gas or electric heating components with increasingly complex electronic controls, so the same symptom can have very different underlying causes depending on your specific model.
A worn or dirty igniter (gas models)
The leading cause of a burner or oven that clicks repeatedly without lighting — grease and food debris on the igniter tip is often enough to prevent reliable ignition.
A burnt-out heating element (electric models)
Each electric burner has its own element, so a single burner failing usually points directly at that element rather than a wider electrical issue.
A faulty burner socket
This small connector underneath an electric cooktop links the internal wiring to the heating element — when it fails, a burner may heat intermittently or not at all, even with a good element.
Blocked gas burner ports
Grease buildup can restrict gas flow enough to cause weak, uneven, or failed ignition even when the igniter itself is working.
A miscalibrated temperature sensor or thermostat
Can cause an oven to run hotter or cooler than the set temperature without any other obvious symptom.
A cracked cooktop surface
Beyond the safety concern, a crack can allow spills to reach the internal wiring and heating components beneath the glass.
Signs You Need Professional Repair
A burner clicks repeatedly without lighting
Usually a dirty or worn igniter, though a faulty igniter switch can cause the same symptom.
The oven takes noticeably longer to preheat
Often an early sign of a weakening heating element or igniter, before it fails completely.
Food consistently comes out under or overcooked
Points to a miscalibrated temperature sensor even if the oven otherwise seems to run normally.
A visible crack in the cooktop glass
Should be treated as a priority — this is a safety issue, not just a cosmetic one.
Burning smells or sparking near heating elements
Warrants stopping use and having the unit inspected before the next use.
Common Problems
Oven not heating is most often caused by a failed bake or broil element on electric models, or a worn igniter that isn't drawing enough current to open the gas valve on gas models.
Stove burner not working can mean different things depending on the burner type: on electric cooktops, it's usually the heating element or the burner socket beneath it; on gas ranges, a clogged burner port or a failing igniter switch is the more likely cause.
Gas stove won't ignite typically comes down to a dirty or worn igniter, though blocked gas ports from grease buildup or a faulty gas valve can produce the same symptom.
Cracked cooktop is a problem we treat with urgency, since a damaged glass surface can let spills reach the wiring and heating components underneath — this is a safety issue in addition to a performance one, and the surface itself typically needs replacement rather than a patch repair.
How Professionals Diagnose the Problem
For ignition issues, we test the igniter's current draw directly rather than assuming it's simply dirty — a weak igniter and a completely failed one look identical to the eye but require different fixes.
For electric cooktops and ranges, we test continuity through the burner socket and switch in addition to the heating element itself, since a good element paired with a failed socket produces the exact same symptom as a bad element.
Temperature and calibration complaints are diagnosed by comparing the oven's actual internal temperature against what the control board believes it's maintaining, using a calibrated probe rather than guesswork.
Repair Process
We explain the diagnosis in plain terms and provide a fixed price before any repair begins.
Igniter, element, socket, and sensor repairs use common replacement parts carried on the service vehicle. A cracked cooktop surface replacement may take slightly longer if a model-specific part needs to be sourced after diagnosis.
Every repair concludes with a full operational test — confirming burners ignite reliably and the oven reaches and holds its set temperature — before we consider the job finished.
Repair vs Replacement
Ranges and ovens have one of the longer useful lifespans among kitchen appliances, typically 13–15 years, which makes repair the right call in the large majority of cases we see.
Is it worth repairing an oven?
In most cases, yes — igniter, element, sensor, and socket repairs are affordable relative to a new range and resolve the issue completely.
A cracked cooktop on an otherwise functional range
Usually a straightforward, worthwhile surface replacement rather than a reason to replace the entire unit.
Control board failure on a range older than 12 years
This is where comparing repair cost against a new range starts to make sense.
Satisfaction with your current range's layout and capacity
If you like your current range otherwise, repair almost always preserves better value than starting over with a new unit.
Preventive Maintenance Tips
Clean gas burner ports regularly
Dried food and grease buildup is one of the most preventable causes of ignition problems.
Avoid warped or rough-bottomed cookware on glass cooktops
Can scratch the surface and stress it unevenly over time.
Use the self-clean cycle sparingly
Excessive heat cycling can accelerate wear on heating elements and control boards.
Check that oven racks sit level
A warped rack can create the appearance of uneven baking that isn't actually a heating problem.
Inspect the door seal periodically
A worn gasket lets heat escape, forcing the oven to run longer and hotter than the set temperature.
Safety Tips
Stop using a cracked cooktop immediately
Spills can reach live wiring beneath the glass, which is a genuine shock and fire hazard, not just a cosmetic issue.
If you smell gas, don't attempt any repair yourself
Leave the home, don't operate switches, and contact your gas utility before calling for appliance repair.
Never ignore a persistent burning smell
Can indicate exposed wiring or a failing element and should be inspected before further use.
Unplug or shut off the gas supply before inspecting components
Ranges combine both electrical and combustion elements, and each requires its own precaution.
Cost Factors
Oven, stove, and cooktop repair cost depends heavily on the specific component. Igniters and thermostats are generally the most affordable repairs; burner sockets and heating elements cost a bit more. Control board or cooktop surface replacement is on the higher end due to part cost.
Premium range brands with induction cooktops or advanced convection systems can carry higher parts costs than standard electric or gas models.

Frequently Asked Questions
Why won't my oven heat?
On electric ovens, this is usually a failed bake or broil element or a tripped thermal fuse. On gas ovens, a worn igniter that isn't drawing enough current to open the gas valve is the leading cause.
Why is my stove burner not working?
On electric cooktops, a failed heating element or a faulty burner socket beneath it is the usual cause. On gas ranges, a clogged burner port or failing igniter switch is more likely.
Why won't my gas stove ignite?
A dirty or worn igniter is the most common cause. Blocked gas ports from grease buildup or a faulty gas valve can produce the same symptom.
Why is my cooktop cracked?
Cracks typically result from thermal shock, a heavy impact, or stress from incompatible cookware. A cracked cooktop should be taken out of use immediately, since spills can reach the wiring beneath the glass.
Is it worth repairing an oven?
In most cases, yes — igniter, element, sensor, and socket repairs are affordable relative to a new range and fully resolve the issue. Control board failure on a range older than 12 years is where replacement is worth comparing.
How much does oven or stove repair cost?
It depends on the component — igniters and thermostats are generally the most affordable, while control board or cooktop surface replacement costs more. We provide a fixed quote after diagnosis.
Do you repair both gas and electric ranges?
Yes, our technicians are trained and equipped to diagnose and repair gas, electric, and dual-fuel ranges, ovens, and cooktops.
Why does my oven take so long to preheat?
A weakening heating element or igniter is the most likely cause, especially if this has developed gradually rather than happening all at once.
Is it dangerous to keep using a cracked cooktop?
Yes. A crack can allow spills to reach live wiring and heating components beneath the glass, creating a real shock and fire risk in addition to the visible damage.
Do you offer same-day oven repair?
Same-day appointments may be available based on technician availability, service location and the time the request is received. Support hours are Monday–Saturday, 9:00 AM–5:00 PM Central Time.
What brands of ranges do you repair?
We service all major range and cooktop brands, including GE, Whirlpool, KitchenAid, Cafe, SMEG, Frigidaire, and Samsung, among others.
Why is only one burner on my electric cooktop not working?
This points directly at that burner's individual heating element or its burner socket, since each electric burner operates independently of the others.
