I'm having issue with the back left stovetop burner on this unit.

I'm getting obvious spark from the ignitor, however there does not seem to be enough gas flow to light the burner reliably. Sometimes it'll light but most times it does not. Gas smell is present so there is some flow for sure.

When it is lit, whether from the auto ignitor or manually, the flame is very low. The high setting is about what the low should be and low will barely stay lit. Flame is an even blue. Seems that there's not enough gas getting through to the burner?

I've taken the burner off and inspected. There's nothing clogging anything there, so I assume the issue would be either the valve or the orifice assembly.

Is there a way to determine which it would be (or if it is either)? I'd prefer to only buy one part if at all possible.


Thanks for any help
