Oven and range repair guides covering uneven heating, gas igniter diagnosis, error codes, and safety checks for all major brands.
Oven problems show up when the stakes are highest — Thanksgiving turkey, a dinner party, or a weeknight meal when nothing else will do. Uneven heating, a gas burner that clicks but never lights, a self-clean cycle that locks the door permanently, or an error code that kills power to the entire unit: these are the scenarios our guides walk you through step by step, from initial diagnosis through the repair decision.
Gas and electric ovens fail differently and we separate the guides accordingly. Gas oven igniter replacement is the single most common oven repair in our service records — the silicon carbide igniter draws current through a safety valve, and when its resistance rises above the threshold, the valve never opens even though the igniter glows. Electric ovens more often suffer bake or broil element burnout, temperature sensor drift that causes 25-50 degree swings, and control board relay failures on models with electronic controls.
For dual-fuel ranges and commercial-style units (Viking, Wolf, Thermador), we include the specific calibration procedures and error code tables that differ from their residential counterparts. These high-end units require specialized service and our guides tell you exactly which repairs are safe for a homeowner and which demand a certified technician.

Bosch gas burner won't light? Follow the ignition chain — spark, gas, flame sensor, hold — to find the break. A dry, clean igniter fixes most cases; a burner that lights then dies on release is the thermocouple. FlameSelect models are less forgiving of carbon buildup.

Bosch oven making noise? On a modern oven it's almost always a fan — the convection fan or the cooling fan. Here's how to tell which and what's normal.

A Bosch oven element that won't heat is usually a burned-out element, a control-board relay, or a blown thermal fuse. Which mode fails tells you which element to test.

A burning smell from a Bosch oven is usually food or grease residue, an electrical component overheating, or hot insulation. On a new oven it is normal factory burn-off. Here is how to read the smell, ranked by likelihood, with the safety steps.

Rust or corrosion inside a Bosch oven usually starts at chrome rack rails, an enamel chip, or a degraded EcoClean coating. Here is where Bosch cavities corrode, ranked by likelihood, plus how to tell rust from baked-on carbon and what is worth repairing.

Bosch oven overheating or running too hot? Diagnosis of temperature sensor drift, stuck relay on control board, and calibration issues on HBL/HBN series with...

A Bosch oven door problem is a worn hinge spring if the door won't stay closed, or the self-clean lock if it won't start or won't release. A door stuck locked after self-clean is usually just still too hot.

A Bosch oven door that won't unlock or locks intermittently is most often a stripped lock-motor gear, then a board relay locking during baking, a bimetallic switch holding a hot door, a microswitch fault, or wiring. Emergency unlock steps and how to diagnose each.

Most likely: the self-clean lock has not released — either the lock motor was damaged by pyrolytic heat, or the control board is stuck in self-clean and keeps the lock engaged. Bosch ovens only unlock once the cavity drops below 280C/550F, so the very first move is patience: wait at least an hour…

Most likely: a failing convection fan motor — its bearings run in brutal heat (the rear wall it mounts through hits 200C-plus) and degrade into grinding and scraping, loudest in convection mode. A rattle from above the door instead points at the separate cooling fan, and a sharp popping with a…

Most likely it depends on what is escaping: steam from the top vent is normal, but steam from the door edges means the gasket has hardened and lost its seal. Heat off the door points to cracked inner glass, water is often condensation from venting, and a rotten-egg gas smell is an emergency. Identify what leaks and from where first.

Most likely: a sagging or dropping door is worn spring hinges, while cloudy or cracked panels, a hardened gasket, or a stuck self-clean lock cover the rest. Nearly every Bosch door repair starts the same way — remove the door by opening it to 15 degrees and flipping the hinge locks…

Most likely: a drifting NTC temperature sensor — Bosch aborts the cycle when its sensor reads out of range, and drift is the leading cause. A self-clean door lock not engaging, a blown thermal fuse, a surge-damaged board (E005/E006), or a failed convection fan are next. Note how far into the cycle it stops, and read the E-code…

Bosch oven baking unevenly? Diagnosis of European Convection fan failure, dual-element cycling issues, and temperature calibration on HBL/HBN series with BSH...

Bosch oven smells like gas? How to tell a normal ignition-delay whiff from a real leak, the ranked causes led by a weak igniter, and the emergency steps.

Bosch oven not reaching temperature? Zero heat points to the bake element or gas igniter; weak heat points to a drifted temperature sensor. Ranked causes, meter tests, and the E005/E011 codes.

A Bosch oven that will not start self-clean usually has a door-lock, temperature-sensor, or control fault blocking the pyrolytic cycle. Here is the ranked diagnosis.

A Bertazzoni oven door stuck shut is usually a self-clean lock that never released, a broken hinge spring, or a failed lock motor. Here is how to free it without breaking the door.

Bertazzoni Italian range not heating? E1/E4 sensor errors, E3/E6 ignition failures, and control board diagnostics for Bertazzoni Master, Heritage.

Bertazzoni oven running hot or cold? European thermostat calibration, convection diagnostics, and temperature sensor repair for all Bertazzoni series.

Bertazzoni range igniter not working? Expert diagnosis of common causes, model-specific fixes, and repair costs for Bertazzoni ranges. Book same-day repair.

A Bertazzoni oven running hot or cold is usually a drifting temperature sensor or a calibration offset that needs setting. Verify with an oven thermometer before replacing a sensor or element.

A Bertazzoni range that won’t heat is usually an igniter or a gas safety valve not opening, then a failed thermocouple on the European safety system. Causes, why the cooktop can work while the oven won’t, and safe checks.

Whirlpool smart oven F2 E5 occurs when the door lock does not disengage after self-clean. The app shows "Cycle Complete" but the door remains locked.

An Amana oven not heating is usually a weak gas igniter that glows but won't open the valve, or a burned electric bake element. Amana is a Whirlpool platform. EasyBear guide.

An Amana oven door stuck shut is most often a self-clean lock motor with stripped gears, a control board hung in self-clean mode, or a weakened hinge spring. The two simple fixes to try first, plus how to diagnose each cause.

Most likely: the temperature sensor (WPW10181986) has drifted, producing a 20 to 50°F offset. Often the oven just needs a calibration adjustment; a partially failed bake element that undershoots is the other cause. Amana uses the Whirlpool calibration procedure — set the offset before replacing a part.

Most likely: a control-board relay welded shut by a power surge is keeping the element energized, or on gas models a control knob stuck off its Off position. Emergency steps and the fix for the relay, temperature sensor, and knob on Amana ovens.

Amana oven smoking? Grease on the exposed bake element is the usual cause, then new-oven burn-off. When electrical-smelling smoke means arcing — stop now.

Smart ovens add touchscreen displays and Wi-Fi modules that increase repair costs by -400 over traditional models. Real part numbers and repair costs.
