Component test · Range / OvenIn gas ovens the glow-bar igniter is wired in series with the oven safety valve. The valve opens only when enough current flows, so a weak igniter can glow and still not open the valve. Measure amps, not just glow.
Guide · Range / OvenThe spark module only fires when a burner spark switch feeds it power, so constant clicking almost always means a wet or shorted switch. If clicking continues with the switches disconnected, the module is stuck. Clicking only after the burner lights points to the electrode, burner cap or ground/polarity instead.
Guide · Range / OvenOn glow-bar ovens the igniter is wired in series with the gas safety valve; a weak igniter can glow but not pull enough current to open the valve. The igniter current check is an electrical test. Anything involving the gas valve, regulator, orifices or gas lines is off limits: refer to a licensed gas technician.
