The oven light in my Smeg SE366SS-5 has stopped working. I thought it had blow so I bought new bulbs. Is there a way to test them or will I need a professional brought in. Is there a specific failure for this Smeg model
if the bulbs you have are not broken it would mean stripping the cooker to find the fault and testing the circuits with a multi tester
if you cannot do this then yes you will need professional help
