Oven Won’t Heat Up? Common Causes and When to Call a Technician

An oven that won’t heat is one of the most disruptive appliance failures — especially mid-meal-prep. The good news: the most common causes are well understood and usually inexpensive to fix.
Electric ovens: check the bake element first
If you can see the bake element (the coil at the bottom of the oven) and it isn’t glowing red during preheat, it has likely burned out. A visibly damaged, blistered, or split element confirms it. This is one of the most common and most affordable oven repairs.
Gas ovens: the igniter is the usual suspect
In a gas oven, the igniter has to glow hot enough to trigger the gas valve to open. A weak or failing igniter may glow but never get hot enough, meaning the burner never lights — or it clicks repeatedly without ever igniting.
Other common causes
- Faulty temperature sensor — the oven may heat, but inaccurately, leading to undercooked or burnt food even though “something” is happening
- Control board failure — less common, but can prevent heating elements or igniters from receiving power at all
- Broken door seal — on its own this usually causes uneven cooking rather than total no-heat, but combined with another issue it compounds the problem
Is it safe to keep using a gas oven that won’t light?
If you smell gas at any point during this troubleshooting, stop immediately, turn off the gas supply, ventilate the area, and call a professional — don’t attempt further diagnosis yourself.
What a technician checks, in order
- Confirms power/gas supply is reaching the unit at all
- Tests the bake element or igniter directly with a multimeter
- Checks the temperature sensor reading against actual internal temperature
- Inspects the control board only after ruling out simpler causes
Most bake element and igniter replacements are completed in a single visit. See our oven & stove repair page for typical pricing in the Harrisburg area.
Frequently Asked Questions
How much does it cost to replace a bake element?
Most bake element replacements run on the lower end of the typical $150-$380 oven repair range, since the part itself is inexpensive and the job is usually quick.
Can I replace an igniter myself?
It’s a common DIY repair for confident homeowners, but because it involves a gas component, many people prefer a technician to confirm the diagnosis and handle it safely.
Why does my oven heat unevenly instead of not at all?
That’s more often a temperature sensor or door seal issue than a fully failed element or igniter — worth mentioning to your technician since it points to a different diagnosis.
