GE JGB735SPSS 5.0 cu ft Freestanding Gas Convection MECH-VALVE Error Fix: Gas Safety Valve Not Opening

The oven gas safety valve does not open even though the igniter is glowing properly — first verify the igniter is drawing adequate amperage (3.2+ amps for most GE models); if the igniter amps are normal but gas still does not flow, the safety valve itself has failed; the safety valve is connected to the gas supply line near the oven burner assembly; replacement requires turning off the gas supply and carefully disconnecting the gas fitting; always use a leak detector solution (soapy water or commercial leak detector) on all connections after replacement to verify no leaks
