GE JGB660 Gas Range — Problems & Repair Guide

The JGB660 is a 5.0 cu. ft. GE gas range with sealed burners, a center oval burner, and edge-to-edge grates. Its faults are almost all igniter and gas-valve related, so a little diagnostic knowledge goes a long way. Here is the ranked data and the safety essentials.

Spec at a glance#

Ranked failures#

1. Oven igniter weakens — 24%. As the igniter ages it draws fewer amps — enough to glow but not enough to open the gas safety valve — so the oven will not heat.
2. Surface igniter clicks continuously — 18%. Moisture or a dirty igniter keeps a surface burner sparking after it lights.
3. Gas safety valve sticks — 12%. The igniter glows but no gas flows because the valve will not open.
4. Edge-to-edge grate cracks — 10%. Thermal shock cracks a grate, usually from a cold pot on a hot grate.
5. Oven thermostat calibration drifts — 8%. Baking temperatures read off from the set point.

Gas safety and the igniter test#

The oven igniter is the heart of most no-heat calls. The igniter must draw 3.2-3.6 amps to open the valve. A technician can measure this with a clamp meter. Replacement is the fix — the igniter cannot be adjusted or repaired. Before calling for service, verify the gas supply valve is ON. For continuous clicking, dry the igniter area thoroughly. Watch the oven igniter through the bottom vent — a bright orange/white glow within 60 seconds is normal; if it glows but gas does not ignite, the safety valve or igniter amp draw is the issue. For cracked grates, avoid thermal shock — do not place cold pots on hot grates.

Fault signals and reset#

The JGB660 uses indicator lights and beep patterns rather than alphanumeric codes. If a light flashes or the unit beeps continuously, try a power reset first: unplug the unit (or flip the circuit breaker) for 60 seconds, then restore power. If the behavior returns, the underlying issue requires professional diagnosis.

Fix or replace?#

Gas ranges are long-lived, and igniters, valves, and grates are inexpensive parts, so repair is the clear choice while the range is sound and the fix stays under half the price of a comparable new range. Replacing an igniter or a grate is a fraction of a new gas range, so these repairs almost always win.

Getting the most out of your JGB660#

A few habits keep a gas range dependable. Keep the burner ports and igniters clean and dry, since a wet or grease-fouled surface igniter is the usual cause of continuous clicking. Let grates cool before cleaning and never set a cold pot on a hot grate — thermal shock is what cracks the edge-to-edge grates. If baking drifts, check the oven against an independent thermometer before adjusting anything. Because a slow-to-light oven igniter is your earliest warning of a failing igniter, replace it when lighting starts to lag rather than waiting for a complete no-heat failure. With that care, the JGB660 stays a reliable range for years, and its common faults remain cheap, well-understood repairs.
