Gas oven that won't heat or barely reaches temperature? Here are the 4 real causes with exact diagnosis steps and what each repair costs in Carroll County.
A gas oven that won't heat almost always comes down to one of four parts. In more than 80% of cases it's the igniter. This guide covers each cause so you know exactly what you're dealing with before calling anyone.
The gas oven igniter has two jobs: draw enough current to open the gas safety valve, and glow hot enough to ignite the gas. A weak igniter glows orange but never draws enough current to open the valve. The oven tries to heat, the igniter glows for 90+ seconds, and nothing happens. The burner never lights.
A completely dead igniter doesn't glow at all. The oven starts its cycle, nothing visibly happens, and the panel eventually shows F3 or a similar error.
How to check: Start oven on Bake at 350°F. A healthy igniter glows bright orange-white and lights the burner within 60–90 seconds. Dim glow past 90 seconds without lighting = weak igniter.
The gas safety valve contains 2–3 solenoid coils that open to allow gas flow when the igniter draws sufficient current. These coils can fail even when the igniter itself tests good. Key distinction from a weak igniter: the igniter glows bright and hot — full current — but the burner still never lights. The igniter is fine; the valve won't open.
The RTD probe at the upper rear of the oven cavity tells the control board the oven temperature. When it fails, the oven may shut off too early, overheat wildly, drastically undercook, or in some cases refuse to heat at all. Common error codes: F1, F3, F4 on most brands.
Test: Room-temperature resistance should read approximately 1,080 ohms. Significantly higher, lower, or open circuit = failed sensor.
The control board manages the oven's ignition sequence. A failed board can cause the oven to display errors, an unresponsive panel, or no heating at all even when the igniter and sensor test good. Control board replacement ($200–$400) should only happen after the igniter and sensor are confirmed working — misdiagnosis here is expensive.

The igniter is weak — glowing but not drawing enough current to open the gas valve. Replacement costs $110–$220. Call (470) 601-9102 for same-day service.
Usually yes — stovetop and oven bake burner use separate igniters. If you smell gas anywhere, shut off the supply valve and don't use any burners.
Igniter: $110–$220. Sensor: $90–$190. Valve coil kit: $90–$200. Control board: $200–$400. See our full cost guide →
Almost always yes — gas ranges last 15–20 years. An igniter repair at year 7 is very good value. See our repair vs replace guide →
