I have a Frigidaire Gallery dual fuel range. On the left side, the smaller burner is located in the front and I want the smaller burners in the back. Is there any reason why I should not swap the jets and burners?
The gas orfices are sized for the BTU heating of each individual burner. A burner that does not match the required orfice size of that burner may not be able to burn the gas supplied correctly: ie. too much gas, not enough air at max flame.
There's no issue, but you have to swap also the giglers. If you swap only the burners you'll have a big burner that won't lit due to too few gas and a little burner burning too high ruining your pans due to oversized gas flow.
