Wall ovens, double ovens, and steam ovens differ from ranges in that the cooking element is the whole unit — there's no stovetop to fail separately. We service every common configuration: single wall oven, double wall oven, steam ovens, and combination microwave-convection ovens. Gas oven work is handled by gas-licensed technicians.
How a oven works
An oven heats food via a bake element on the bottom (electric) or a gas burner (gas), and broils via a separate element on the top. A thermostat or temperature sensor tells the control board when to cycle the elements on and off to maintain set temperature. Convection ovens add a fan to circulate hot air. When something fails, the symptom points to the heating elements, the temperature control, or the door/latch mechanism.
What we typically fix
- 01
Won't heat to set temperature
Could be a failed bake element (electric — you'll see visible damage to the coil), a failed igniter (gas — won't glow bright orange), or a failed oven temperature sensor (the thermostat thinks the oven is hotter than it is and cycles off too early). On electric ovens, also check the breaker — ovens run on dual 240V circuits.
- 02
Uneven cooking
Usually the convection fan motor has failed (convection oven) or the bake element is heating unevenly because part of it has burned out. Less commonly, the temperature calibration has drifted (most ovens have a calibration setting in the control panel).
- 03
Self-clean lockout
Self-clean cycles run very hot (up to 500°C) and lock the door for safety. If the lockout doesn't release after the oven cools, the door lock motor or the temperature sensor that detects cool-down has failed. Sometimes the control board has glitched and a full reset clears it.
- 04
Igniter failure (gas)
Gas ovens use a glow-bar igniter to light the gas — it glows bright orange when working. Old igniters glow dimly, which means they're drawing less current than needed to open the gas valve, so the gas doesn't light. Usually the symptom is 'I hear gas hissing but no flame.'
- 05
Door hinge or seal damage
Door hinges fail by losing tension (door doesn't stay closed or won't open all the way) or by snapping (visible spring damage). Door gaskets fail by hardening over years — once cracked, they leak heat and the oven works harder. Both are routine replacements.
Types of ovens we service
Different builds fail in different ways. Here's what we see most often across each type.
Single wall oven
A standalone oven installed at counter or eye level, separate from the cooktop. Common in mid-to-high-end kitchens. Service is mostly straightforward — most parts are accessible without pulling the unit from the wall.
Double wall oven
Two ovens stacked in a single cabinet opening. Each oven is electrically and mechanically independent — one can fail while the other works. Slightly harder to pull for service since both must be carefully removed together.
Steam oven
Uses water (filled via a tank or plumbed in) to generate steam for cooking. Common high-end brand: Miele. More electrical components than a standard oven (steam generator, water pump, drain) and more service points around the water system.
Combination microwave / convection oven
Combines microwave function with conventional baking and/or convection. More complex electronics than a single-function oven. Magnetron failures (the microwave side) are a common service issue.
Signs your oven needs repair
- Oven takes much longer to preheat than it used to
- Food browning unevenly even with rack rotation
- Door doesn't stay closed at any angle
- Visible damage to the bake or broil element
- Gas smell when oven is on or off (immediate concern)
- Self-clean cycle won't unlock
- Touch panel intermittent
Try these before booking
Quick checks that resolve a meaningful share of oven calls without a tech visit.
- 01
Check the breaker (electric)
Electric ovens run on a dual 240V circuit with two breakers. Sometimes only one trips — bake might work but broil doesn't, or the oven runs but doesn't get fully hot. Check both.
- 02
Check the gas supply (gas)
Confirm the gas shutoff valve to the oven is fully open. If your gas range has a stovetop and the stovetop also isn't working, the issue is likely at the gas supply rather than the oven.
- 03
Calibrate the temperature
Most modern ovens have a temperature calibration setting accessible through the control panel (check your manual). Calibration drift over years is normal and adjustable up to ±15°C / ±25°F.
- 04
Check the door hinges and seal
Open the door fully and look at the hinges for visible damage. Close the door and check the gasket — if it has cracks or compressed flat sections, it needs replacement.

Before our visit
What to do
- Cool the oven down completely before our visit
- Remove racks and any bakeware inside
- Locate the gas shutoff valve (if gas) or the breaker panel (if electric)
- Photograph any error code on the display
Finding the model number
Model number is on a sticker inside the door frame (visible when door is open), behind the storage drawer (if present), or on the side of the oven cavity. A photo works.
Safety
Gas oven work is performed by gas-licensed technicians. If you smell gas at any time, leave the home, call your gas utility's emergency line from outside, and do not operate the oven or any electrical switch until cleared. We coordinate with licensed gas installers for any supply-side work.

Why is my oven taking forever to preheat?
What does it mean when my oven displays an F-code error?
Why won't my self-clean cycle unlock?
Should I use self-clean?
Why does my oven smell when first heated?
Can I convert my gas oven from natural gas to propane (or vice versa)?
Why is my convection fan making noise?
How long should a wall oven last?
Why does my oven door drop when I open it?

Worth knowing
How long ovens last
13–17 years for standard wall ovens; 18–22+ for premium and steam ovens with maintenance. Bake elements, igniters, and sensors are the most common parts to fail. Control boards are the most expensive single failure point on electronic models.
What we don't service
We work on residential and small light-commercial ovens. We don't service commercial convection ovens, deck ovens, or pizza ovens.
