An oven that won’t heat picks the worst moments to quit — usually with something already on the counter waiting to go in. The good news: in most Denver Metro service calls this is one of a short list of parts, all of them very repairable. Here is what actually fails, and how to tell which one you are looking at.
Electric ovens: the bake element
The glowing loop at the bottom of the oven does most of the work, and it fails two ways: dramatically — a visible blister, a burn spot, sometimes a small fireworks show — or quietly, where it simply stops glowing. If the broil element up top still works but bake does not, the bake element is the prime suspect. It is an affordable part we usually carry for common GE, Whirlpool and Frigidaire ranges.
Gas ovens: the igniter
Gas oven igniters are the classic slow death: the igniter glows, so it looks alive, but with age it no longer draws enough current to open the safety gas valve. The result is an oven that clicks or glows and never lights, or takes ten minutes to catch. If your burners work but the oven won’t light, the igniter is the usual culprit — and a glowing igniter fooling the eye is exactly why this one gets misdiagnosed at home.
The temperature sensor
A drifting oven sensor makes the control think the cavity is hotter or colder than it is: burnt cookies at 350, raw centers, an oven that heats then gives up, or an F-code on the display. Sensors are cheap; the skill is in confirming the sensor rather than the board is lying, which is a resistance test, not a guess.
The control board and the thermal fuse
When nothing heats at all — no bake, no broil, dead display, or a board that beeps error codes — the electronics enter the picture. Some ranges also hide a thermal fuse that blows after a self-clean cycle (a very common story: “it stopped heating right after I ran self-clean”). The fuse is a small part; the board is the expensive branch, which is exactly why we test before ordering.
Why we don’t recommend guessing parts
Element, igniter, sensor, fuse, board — the symptoms overlap, and the prices don’t. Swapping parts in price order is how a $180 repair becomes a $450 one. Live diagnosis with a meter tells us which part failed before anything is ordered, and our diagnostic fee is credited toward the repair.
Repair or replace?
Ovens age gracefully: no compressors, no sealed systems. Elements, igniters, sensors and fuses are all solidly worth fixing at almost any age. The honest exception is a failed control board on a discontinued model — if the part alone approaches half the cost of a new range, we will say so before you commit.

Oven Not Heating FAQ
My oven turns on but never reaches temperature — same problem?
Usually yes, in a milder form. A weak igniter or a partially failed element heats slowly and stalls low; the control then overshoots and undershoots. The same diagnosis finds it.
Can I replace a bake element myself?
It is one of the simpler repairs, but element failures sometimes take out the fuse or damage the receptacle, and gas igniters involve the gas path — where guessing gets expensive or unsafe. A diagnosis first costs less than a second part order.
Why does my gas oven click but not light?
Clicking is the spark module trying. If the burner never catches, the igniter is usually too weak to open the gas valve — a classic amperage failure that still glows visibly, which is why it fools DIY checks.
Is it worth fixing a 10-year-old oven that won’t heat?
Usually yes. Elements, igniters and sensors are inexpensive relative to a new range, and ovens don’t have a sealed-system-style catastrophic failure mode. We will tell you honestly if the control board changes that math.
