Understanding the Problem
If your GE model FGSC2335TF7 oven won’t reach the temperature you set (food undercooks, cycles excessively, or temperature is inconsistent), the issue is usually with one of a few critical components that control ignition and temperature sensing. In gas ovens the two most common culprits are a weak/glowing-but-not-strong-enough igniter and a faulty oven temperature sensor (thermistor). Either will prevent the gas valve from opening correctly or will give the control board wrong temperature readings. Less commonly, a failing gas safety/oven valve or an electronic control board problem can cause the same symptoms. Before ordering parts, it’s best to perform a few simple checks — confirm actual oven temperature with an independent oven thermometer, watch the igniter during a bake cycle, and test the temperature sensor resistance — so you replace the correct component and avoid unnecessary expense.
Common Symptoms
Oven takes a long time to preheat, never reaches set temperature, food undercooks, igniter glows but burner does not light, or oven cycles frequently and temperature fluctuates.
Common Causes
- Weak or failing oven igniter (glow igniter) that cannot open the gas valve
- Faulty oven temperature sensor (thermistor) reporting incorrect temperature to the control
- Defective gas safety/oven valve or control board preventing proper gas flow or control

Helpful Repair Tip
Place an oven thermometer on the middle rack and preheat to 350°F. If the oven takes much longer than expected to reach 350°F or never reaches it, watch the igniter: if it glows but the burner never opens, the igniter is likely weak and needs replacement.
Frequently Asked Questions
How can I tell if the igniter is the problem?
Start with an oven thermometer to confirm the oven isn’t reaching temperature. Then run the oven and watch the igniter through the oven window: a healthy igniter glows bright orange and lights the burner within 30–90 seconds. If it glows dimly or glows but the burner never lights, the igniter is weak and should be replaced. For a more accurate test you can measure igniter current with a multimeter (requires service knowledge).
Can I replace the parts myself or should I call a technician?
If you are comfortable turning off gas and power, removing the oven bottom and accessing components, you can replace common parts like the igniter or temperature sensor yourself using the correct OEM replacement and following safety steps. However, because this appliance involves gas and sealing, if you’re unsure, or if replacing the igniter doesn’t fix the issue (suggesting a gas valve or control problem), call a qualified appliance technician to diagnose and safely repair the range.
