Bertazzoni HERT486GDFSAVT Dual-Fuel Range Repair

A 48-inch Heritage Series dual-fuel range, the HERT486GDFSAVT has six brass burners and a griddle above an electric self-clean oven. Gas and a 240-volt supply both need to be present, and the kitchen around it is usually built for serious cooking.
We light the burners and the griddle and look for flames that are steady and even. The griddle plate is checked for cold areas, since they point to blocked ports or a plate that does not lie flat. The oven is measured against a thermometer, and the self-clean latch is cycled to be sure it releases. Any burner that clicks without lighting gets its port cleaned first.
Gas smell means leaving the house and calling the gas utility from outside. We give a written price before work begins.
Residue in the burner ports or a plate that does not sit flat causes cold spots. We clean the ports, check that the plate is level and seated, and relight the burner to see whether the heat is even.
We use a separate thermometer to measure the oven at the center, then test the sensor resistance. If the sensor has drifted, we replace it and verify the oven against the dial again.
Let the oven cool completely first. If it is still locked, the latch motor or its switch is likely stuck from the heat, so we test the circuit and replace the part that fails.
