The oven never reaches the temperature you set
Gas or electric changes this fault three times over: what failed, what it costs, and who is allowed to open it. Across 333 of the 1,713 completed jobs in this dataset behind this page [S2], one part accounts for more of these failures than every other put together: weak or failed gas igniter, 209 jobs at $210–$380 installed [S2]. The next largest is one part at 87 jobs, and the second group together is 124. That concentration is the useful part of the diagnosis: the oven never reaches the temperature you set - described as oven never reaches the set temperature, bake element stays dark, gas oven glows but never lights or takes forever to preheat - usually has one short list of causes, and they sit close together in price.
333 of the 1,713 completed jobs in that dataset [S2] sit behind the counts above. Each figure is the source's own median invoice - parts, labour and the service call together, never the part alone.

gas oven glows but never lightsoven never reaches the set temperature
The single most replaced component in S2's dataset: median $350 across 209 completed jobs. It is a wear part by design - it glows red hot every cycle until it can no longer pull enough current to open the gas valve. S1 gives the electrical tell: below roughly 3.2-3.6 amps the valve never opens, and a glow that runs past 90 seconds with no flame means the igniter is failing even though it looks alive. S1 prices the job at $210-380. Time basis: no published duration, book estimate.
the igniter is priced as an installed job, never as a bare part; the retail part is around $30 (S2) but no part-only installed figure is claimed

oven never reaches the set temperaturetakes forever to preheat
S2 medians this at $420 across 19 jobs and S1 puts the sensor job at $160-260. This is the fault behind an oven that heats but not to the number on the dial. S1 gives the reference reading for the RTD probe in the upper rear of the cavity: about 1080 ohms at room temperature; a probe knocked against the oven wall reads the wall instead of the air. Time basis: no published duration, book estimate.
priced as an installed job, so no part-only figure is claimed
The most expensive standard oven repair: S2 medians $469 across 87 jobs, S1 puts boards at $180-450 installed. Relays fail with burned contacts, often visible as a scorched spot. The sources that price it say to confirm it carefully, because a failed sensor produces overlapping symptoms for less money and a burnt element can take a board out with it. Time basis: no published duration, book estimate.

Repair or replace?
The verdict
An igniter or element at $319-350 against a $1,000 range is not a close call at any age. A sensor at $420 still comfortably favours repair under fifteen years; a control board at $469 is where it gets closer past fifteen. A built-in wall oven wins on repair almost regardless, because replacement means matching a cabinet cutout that may no longer be a standard size. [S2]

The source behind the counted causes on this page publishes a job count for four of them, all four in its own by-part oven cost table: gas igniter 209, bake element 18, thermostat or temperature sensor 19, control board 87. The remaining two causes have no count because neither is a part replacement: one leg of the 240-volt supply lost is a supply fault the other cited source describes without a number, and a normal temperature swing is explicitly not a fault at all. The source publishes its own floor for the table - part-level cells with fewer than ten completed jobs are not published - and it publishes no calibration line at all, because across its records an oven at the wrong temperature either needs a part or needs nothing. Two of six causes hence stand without a denominator. The same publisher also keeps a brand page written around this exact fault for one manufacturer, and it prints a sample there that the general oven table does not: across 1,858 completed oven repairs its median invoice is $375, with the middle half between $300 and $482. That figure is a brand slice of oven work rather than a sample of this fault in general, which is why it is printed above beside the cost table with its own source named instead of being bound as this page's own count, and it is not added to the 1,713-job table the counted causes come from. The five part rows of that same table are printed above as labelled bands, each with its own count, and each with no middle half: the source publishes a per-part median and a job count rather than a quartile split, so the absence of a middle half is the source's limit and is stated on the page rather than filled in.
A new freestanding range is $700-1,500 before delivery and installation, and a built-in wall oven runs well past that.
S2 sets its decision line at fifteen years: a sensor or thermostat repair comfortably favours repair under fifteen, while a control board past fifteen is where the arithmetic gets closer

bake element stays darkoven never reaches the set temperature
S2 publishes two rows for element work rather than one: 57 heating-element jobs at a $319 median and 18 bake-element jobs at $322. They are two rows of the same table and not one count, so this cause carries the bake-element row on its own and the two rows are not added together. Failure is usually visible: the element blisters, cracks or shows a bright burn spot, and because it is a resistive loop it either works or it does not - an oven that heats slowly but does get there is more likely a sensor problem. S1 adds the two-minute test: a healthy bake element glows evenly orange during preheat. Time basis: no published duration, book estimate.
S1 and S2 both quote the element job installed ($180-320 and a $322 median); no part-only price for this record is claimed

Electric ranges take 240 volts as two 120-volt legs: lose one at the breaker or in the cord and the surface burners and the clock still work while the oven cannot heat. S1's proof test is the broiler - if broil works but bake does not, the board, thermostat and supply are all fine; if neither element heats and the cooktop is fine, test both legs at the terminal block before buying any part. Free to check.

Worth ruling out before booking: put an oven thermometer on the middle rack, set 350F and let it run 20 minutes. A swing of 25-30 degrees around the setting is normal on almost every home oven. S2 also reports that across 65,924 service records there is effectively no standalone calibration job - if a technician finds nothing to replace, the diagnostic is the whole bill.

[S3]Bozmanfix (the same publisher's brand page for this fault, written around Whirlpool ovens) (2026). the brand page's own sample for this fault: across 1,858 completed oven repairs a median invoice of $375 with the middle half between $300 and $482, part, labour and the visit included. Its own by-part rows carry their own counts (igniter $350 n=216, bake element $313 n=24, heating element in other positions $324 n=70, temperature sensor $345 n=15, thermostat $422 n=25) and the $99 diagnostic is waived when the repair is approved. This is a brand slice - the page is written around one manufacturer - and its counts form a separate published sample from the 1,713-job oven and range table (S2): the element rows differ between the two pages (57 and 18 there, 70 and 24 here), so the two are quoted side by side and are never added together or averaged

Quick answers
How much does it cost to fix a oven with this problem?
Completed repairs run $302–$478 according to the sources cited on this page, after a diagnostic fee of $80–$110.
How long does a oven last?
The decision rule used on this page works from a planning life of 15 years.
Repair or replace?
An igniter or element at $319-350 against a $1,000 range is not a close call at any age. A sensor at $420 still comfortably favours repair under fifteen years; a control board at $469 is where it gets closer past fifteen. A built-in wall oven wins on repair almost regardless, because replacement means matching a cabinet cutout that may no longer be a standard size.
