Radiantube burners
Hans,
Xraytech is correct. Guardian Service CAN be used in the oven but it was designed for stove top waterless cooking.
My old Frigidaire had elements just like yours. I DID NOT like using the Guardian Service on the front "speed heat" unit as it provided too much heat too quick.
The controls on my old range top were somewhat different than yours. Mine showed RED the more you turned the heat value up.
They were almost like the old Hotpoint Tel-A-Cook lights. You could tell from across the room which heat was on and how high it was adjusted.
I would start process on a little less than 1/2 for less than 5 minutes and then down to LOW.
When frying, I test the heat till a few drops of water bead up and dance around on the pan.
You should never see vapor coming out under a lid. That indicates too much heat at the start.
Even with the newer glass top range, I start at the same level and NOTHING sticks, even eggs when you do the flip with the omelet pan.
If you have any problems drop me a line. I have been using them over 40 years now and be glad to help you.
Because of the unique bottom with the flange, it traps all the heat and the sides are just as thick as the bottom so it does not take high heat to fry.
You are an experienced cook so you will get it after a few trials and errors. Each range cooks a little different.
As you can see the eggs do not stick. Check out the other side of the omelet pan. I filled it with too much batter but the surface that did the first side baking did not stick.
They work perfect on the newer Frigidaire glass top as every burner has measured, controlled heat values (like the old Heat Minder unit on the Frigidaire).
