I have a Frigidaire Custom Imperial electric range. I need 2 of the 6 in burner units.

Also, where is the serial number located on this stove?

Thanks and Happy New Year~

What is your general location? I may have a suggestion on a parts supplier that I have used several times over many years who may be able to give you a lead on where you might find parts. I assume that the universal burners won't fit up?
