Checked range and found the rear pilots are all low or out . Tried cleaning them but it did no good . Reassembled and ran ovens to 350° and cycle. Temps calibration ok. Only had to adjust the right oven knob. Left and right ovens ok. All top burners work ok. Soap tested all connections and gas hose and quick connect and burner valves and thermostat lines and no gas leaks anywhere. Gas smell may have come from the pilots being out. Will order new pilot kits and return to replace. Unit in service. 9/4/20 Removed grates and burners. removed pilot assy. on all. replaced them with new. put unit back together and lit pilots. adjusted all and turned burners on 1 at a time. they all lit with pilot. unit is operational job complete.
