Hi I have one of these convection ovens ( the one with the glass bowl and stands on a counter. Ref RSH-010910-018 - 97201092 . one evening I set the controls and switched the oven on, A big blue flame came from the dome and now the oven does not work. Can the electrics be repaired or can I purchase a new dome. Kindly advise me accordingly. Thank you Kind Regsards Lynne Botha - 011 395-3240
