Bertazzoni Oven Error Codes — Complete Error Code Diagnosis Guide

Five Bertazzoni oven codes are decoded here, and they divide between sensing and ignition. E1 is a temperature probe read as a short circuit, often the meat probe, its cable, or debris in the jack. E2 is the oven NTC sensor read as an open circuit, and E4 is the same sensor drifted out of range rather than dead — degraded, unseated from the cavity wall, or adding resistance at its connector. E3 and E6 are ignition failures: a weak glow-bar igniter or a gas safety valve that is not opening on the oven side, and a spark module, dirty igniter or thermocouple on the burner side.

The three sensing codes are close enough that the guides spend their effort on telling them apart. E2 and E4 accuse the same NTC part, but one is proved by an open reading and the other by a resistance that is plausible yet wrong for the temperature — which is why a cold-oven measurement at room temperature is the check that settles it. E1 is separated from both by unplugging the meat probe and seeing whether the code goes with it. The ignition pages work in the order the appliance does: spark, flame, then the sensor that has to confirm it.

Ignition faults on a gas range are the clearest boundary in this whole index. A glow-bar igniter that has weakened still glows, so the valve can open with nothing lighting it, and gas keeps arriving — that is not a fault to reset and retry. Gas safety valves, spark modules and thermocouples are professional work regardless of how accessible they look. The sensor codes are gentler ground.
