Bertazzoni MAST366DFSXT Brass-Burner Dual Fuel Service

Six brass burners on a 36-inch top, with an electric self-clean oven below, give the MAST366DFSXT a split personality that cooks like a restaurant range on top and an ordinary oven underneath. It is a freestanding model and is often chosen to make a kitchen feel professional.
Brass burners hold heat well and show wear in a specific way: the caps discolor and the ports collect residue where flames meet the metal. We check cap seating on every burner, test each igniter and watch the flames for evenness. The oven is checked on the electric side: bake and broil elements, sensor and the lock that engages for self-clean.
If you notice a gas smell, call the gas utility from outside the house.
Yes. Heat and cooking residue darken brass gradually. That is cosmetic, but residue in the ports is not. We clean the ports so the flame stays even.
The oven will not run the cycle unless the lock confirms it is closed. A worn lock motor or switch prevents that. We test the circuit and replace whichever piece fails.
Each burner has its own cap, port and igniter, so we inspect them one at a time. Differences are usually a cap off-center or a blocked port, and both are quick to correct.
