You set the oven to 400, waited the usual ten minutes, and the food is still raw. Maybe
it heats a little but never gets hot, or it takes forty minutes to reach a temperature it
used to hit in eight. When your oven is not heating to temperature, the instinct is to
assume the whole range is done. Here is the reassuring part: the repair almost always
lands between $100 and $380, against $500 to $2,000 or more for a new range.
The good news is that “heats a little but not enough” is a different, cheaper problem than
“dead, no heat at all.” A partial heat failure points at a small, specific part that has
drifted or weakened, not at the guts of the machine. The trick is knowing which part, so
you do not pay for the expensive guess.
What actually breaks when an oven will not reach temperature
There are only a handful of parts that control oven heat, and they fail in predictable
ways. Whether you have electric or gas narrows the list fast.
On an electric oven, the usual suspects are:
- Bake element. The looped rod at the bottom of the cavity. A dead one often shows a
visible break, a blister, or a burn spot. But plenty of failed elements look perfectly
normal, which is where people get fooled. If the oven heats weakly, the element may be
partially failing rather than fully dead.
- Temperature sensor. A thin metal probe near the top rear of the cavity that tells
the control board how hot it is. When it drifts, the oven either overshoots or, more
often, never reaches the set point because the board thinks it is already there.
- Broil element only working. If the top element glows but the bottom stays cold,
the bake element is your answer, not the board.
On a gas oven, the list is shorter:
- Weak igniter. This is the number one cause of a gas oven that will not heat
properly, and the most misdiagnosed part in the entire appliance. More on the trap
below.
- Faulty gas valve or safety valve. Less common and more expensive, but real.
- Temperature sensor. Same idea as electric, same cheap fix.
Oven not heating repair cost by failure point (2026)
These are installed prices, part plus labor, for a professional visit. Most techs charge
an $80 to $120 diagnostic fee that is usually credited toward the repair if you go ahead.
Labor runs roughly $65 an hour in rural areas and up to $120 an hour in coastal cities.
| Repair | Part cost | Installed total |
|—|—|—|
| Temperature sensor / thermistor | $20 to $50 | $100 to $250 |
| Electric bake element | $20 to $60 | $150 to $300 |
| Gas oven igniter | $20 to $50 | $130 to $325 |
| Thermostat + bake element combo | $120 | $260 to $380 |
| Control board | $100 to $350 | $250 to $600 |
| Gas safety valve | $30 to $150 | $200 to $500 |
Brand changes the part cost more than anything else. A generic bake element or igniter for
a Whirlpool, GE, Frigidaire, or Kenmore runs $20 to $50. The same part for a Wolf, Miele,
or Thermador can triple, and a high-end control board can push a board swap past $500 on
its own. If you own a premium range, get the OEM part number before you assume a repair is
cheap.
The hidden trap: a glowing igniter can still be a dead igniter
This is the single most expensive misdiagnosis in the oven world, and it costs people new
ranges they did not need.
On a gas oven, the igniter does two jobs. It glows to light the gas, and while it glows it
draws enough electrical current to trip the safety valve open so gas can flow. As an
igniter ages, it still glows, but it weakens and stops drawing enough current to open the
valve. So you stand there watching it glow a dull orange, the gas never lights, and you
conclude the igniter is fine because you can see it working. It is not. **A glowing
igniter that takes more than 90 seconds to light the burner, or never lights it, is a weak
igniter, full stop.** That is a $130 to $325 repair, not a reason to replace a good range.
The electric version of the same trap: a bake element with no visible break can still be
dead. The metal looks fine, so a tech reaches past it to the control board, a $250 to $600
part. A $10 multimeter settles it in two minutes. With the oven unplugged, test the
element for continuity. No continuity means the element is broken internally no matter how
clean it looks. That one test can save you a needless board replacement.
And the cheapest miss of all, on both fuel types, is the temperature sensor. When an
oven heats but never reaches the set point, or the temperature swings wildly, the sensor
is reading wrong and lying to the board. It is a $100 to $250 job and it gets skipped
constantly in favor of pricier parts. Ask any tech to check the sensor resistance before
they quote you a control board.
Quick signs pointing to each cause:
- Gas oven, igniter glows but gas will not light, or lights very slowly: weak igniter.
- Electric oven, bottom element never glows while broil works: bake element.
- **Either fuel, oven runs but is always off by 25 to 75 degrees, or never hits the set
point:** temperature sensor.
- No heat at all, no glow, no click, display acting strange: control board, and the
only case where replacement starts to make real sense on an older range.
Repair or replace: the decision framework
Electric ranges last 13 to 15 years on average, and gas ranges often a few years longer.
A basic new electric range runs $500 to $900, a mid-tier model $900 to $1,800, and premium
or dual-fuel units $2,000 and up, before delivery, installation, and haul-away. Use the
real number for the range you would actually buy as your denominator, not the sticker on a
luxury model you would not.
Repair if:
- The range is under 12 years old and this is its first real failure
- The diagnosis is the sensor, element, or igniter, which are all $100 to $380 sound-machine
fixes
- The quote is under half the price of the new range you would realistically buy
- It is a slide-in, dual-fuel, or matched-set unit that is expensive to replace like for like
Replace if:
- The range is over 15 years old and the quote clears $400
- The failure is the control board on an older unit, at $400 or more, especially past year 12
- You are stacking repairs, a second or third major part in a short span
- The oven has safety issues, a gas smell that persists after an igniter fix, or scorching
around the controls
DIY if: you are comfortable unplugging the range or shutting off the gas at the valve.
A bake element is genuinely one of the easiest appliance repairs there is: two screws
inside the cavity, two wires, ten minutes, and it turns a $250 service call into a $40 part.
A temperature sensor is a similar plug-and-swap. A gas igniter is a moderate job, a couple
of screws and a wire connector, and well within reach for a careful DIYer who matches the
exact part number. Gas valve and control board work, and anything where you smell gas, is
where you call a licensed pro.
One rule before you buy any part: confirm the failure first. A cheap multimeter tests
an element, sensor, or igniter for continuity in minutes and stops you from replacing a
good part on a guess. That single habit is the difference between a $40 fix and a pile of
wrong parts.
Bottom line
An oven not heating to temperature is a $100 to $380 repair far more often than it is a
dead range. The partial heat, the slow climb, the glowing-but-not-lighting igniter, all of
it points at a small part that has weakened, not at a machine that is finished. Test before
you buy, ask the tech to check the temperature sensor before they reach for a control
board, and only let the math tip toward a new range when the unit is past 15 years or the
quote clears half the cost of the one you would actually replace it with.
FAQ
Why does my oven heat up but not get hot enough?
Usually a failing bake element on an electric oven or a weak igniter on a gas oven. Both
lose strength before they die completely, so you get some heat but never the full set
temperature. A drifting temperature sensor causes the same symptom and is the cheapest fix
at $100 to $250 installed.
How do I know if it is the heating element or the temperature sensor?
If the electric element never glows red while broil works, it is the element. If the oven
glows and runs but stays 25 to 75 degrees off the set point, suspect the sensor. A
multimeter continuity test on the element, done with the oven unplugged, confirms it in two
minutes.
Is it worth replacing a gas oven igniter?
Yes, in almost every case. At $130 to $325 installed, and often a $40 DIY part, a new
igniter fixes the most common no-heat gas failure for a fraction of a new range. Replace
the range only if the oven is 15-plus years old and stacking other failures.
When should I just buy a new range instead of repairing?
When the range is over 15 years old and the repair clears $400, when the fault is a
control board on an older unit, or when the quote exceeds half the price of a comparable
new range. Below those thresholds, repair almost always wins.
