My gas oven from 3 years ago has been acting weird lately. When I set it to 180°C, the temperature keeps going up and down constantly and the food comes out cooked unevenly. Is this something I can fix myself or do I need to call a technician?
The first thing is to clean the burner and the gas inlet holes well - they often get clogged with food scraps or dust and that's what causes those temperature swings. If it's still doing the same thing after cleaning, it's probably the thermostat or the gas regulator valve, and at that point you need a technician because it requires special tools and knowledge of the system. It's worth calling someone to check it out, because if it's 3 years old it should still be under warranty or fixable without spending a fortune.
