A while back I dropped something on the front left of my glass cooktop and it splintered. I replaced the cooktop, but not, I am pretty sure, the burners underneath. The front left burner hasn’t worked ever since. I suspect the burner itself is broken but it looks almost perfect. When I say the burner I’m referring to part #15 in the “Top/Drawer” section - Replacement parts for FRG FEF336ASK | AppliancePartsPros.com
The only blemish is a one centimeter square burn/discolored patch on the topside of the burner. The metal coil breaks for that 1 cm gap.
Is it likely that the burner needs to be replaced? Or is there anything else to test before buying the new part?
