Understanding the Problem
The GE JGBS66REK2SS is a common 30" gas range. If the oven won't light or the burners/oven are slow to light or won’t sustain a flame, the problem is usually a faulty igniter, a failing safety gas valve, a bad spark module (for sealed burners), or an issue with the oven temperature sensor or control board. Symptoms may include the igniter glowing but the gas valve not opening, burners that click without lighting, oven taking a long time to reach temperature, or the oven never heating at all. Diagnosing gas-range ignition problems requires both visual inspection and simple electrical checks. Start by observing the igniter: a weak or slow-glowing igniter is the most common cause for an oven that won’t light. Other times the issue is electrical (no voltage to the igniter), a failing safety gas valve, or a broken thermostat/sensor that keeps the control from calling for gas. Always shut off power and gas before you inspect internal components, and confirm model compatibility when ordering replacement parts.
Common Symptoms
Oven won’t light or heats very slowly; igniter glows but burner never opens; surface burners click but do not light; oven cycles erratically or fails to reach set temperature.
Common Causes
- Weak or cracked bake igniter (most common for oven not heating)
- Faulty oven temperature sensor or thermistor causing incorrect temperature control
- Failed gas safety valve or ignition/spark module (no gas flow even when igniter is good)

Helpful Repair Tip
Visually inspect the igniter during a bake cycle: a healthy gas igniter glows bright orange within 10–20 seconds and then the burner lights. A dim, slow-glowing, or cracked igniter usually needs replacement. Use a multimeter to check igniter continuity and verify 120V at the igniter terminals when the oven is calling for heat (use caution).
Frequently Asked Questions
How can I test whether the bake igniter is the problem?
Visually inspect the igniter during an oven start: it should glow bright orange quickly (10–20 seconds). If it glows dim or very slowly, it often does not draw enough current to open the gas valve. With power disconnected, test the igniter for continuity with a multimeter; most igniters show low resistance but a broken element shows open circuit. For a definitive live test (advanced users only): with the oven calling for heat, carefully measure for 120V at the igniter terminals — if voltage is present and the igniter does not glow properly, replace the igniter. If voltage is absent, the problem may be the control board or safety valve.
Can I replace the igniter or other parts myself, and is it safe?
Replacing the igniter is a common DIY repair and is straightforward on many GE ranges, but safety precautions are essential. Always disconnect electrical power at the breaker and shut off the gas supply before starting. Confirm the replacement part number matches your model (JGBS66REK2SS) and follow the service manual or a trusted step-by-step guide. If the issue involves the gas valve, gas line, or you are unsure about live-voltage testing, hire a qualified appliance technician or licensed gas fitter to avoid injury or gas leaks.
