We bought a condo with Frigidaire Gallery Series Dual Radiant Baking and Roasting Range with no manual. How does this oven work? There is no temp gauge.

Could not find this appliance without a model number but here is the contact for frigidaire.

I don't know the model of your Frigidaire stove, so I can't find the concrete manual for you. You can try this site and search for the manual you are looking for by model number: Frigidaire Stove Free PDF Manuals & Guides Download

Good luck.
