When a Bertazzoni flashes E2, it’s flagging a problem with the oven’s fan system—the part that keeps air moving so heat spreads evenly and electronics don’t overheat. If that airflow drops off or stops altogether, the control senses it and throws the code to protect the appliance.
What’s usually behind E2?
Most of the time it comes down to one of three things: a tired or seized fan motor, airflow that’s being choked by grease or debris in a vent path, or a control board that’s no longer sending the right signal to the fan. Daily cooking can bake on residue around the fan shroud and vents, and over years of use a motor bearing can simply wear out. Less often, the electronics themselves are the culprit.
First checks you can do at home
Start simple. Power the oven on and listen carefully—do you hear the fan spool up when the cavity heats, or is it silent, grinding, or pulsing? Odd noises hint at a failing bearing or a bent blade; silence may point to a failed motor or no power reaching it. If the code appears immediately, turn the appliance off at the breaker and give it a few minutes—this hard reset clears transient faults and is safe to try.
If E2 returns, disconnect power and remove the rear panel (or the interior fan cover, depending on model). You’re looking for obvious obstructions: sheets of baked-on grease, foil fragments, a fallen screw, or food residue trapped around the fan guard or vent passages. Clear anything you find and spin the fan blade by hand—smooth rotation is good; stiffness or wobble suggests the motor needs replacement. While you’re back there, follow the wiring harness to the fan and look for heat damage or loose connectors. Restore power and test again; if airflow still doesn’t start or the code reappears once the oven warms, the issue may be electronic rather than mechanical.
When it’s time for a technician
If the fan won’t run even with clear vents and secure wiring, the motor windings could be open, or the control board may not be energizing the circuit under load. Both require proper tools to diagnose—multimeter checks, live tests, and often a parts match to your exact model and serial. A qualified tech can confirm whether a fan assembly swap will solve it or if the control board needs service as well. That visit also ensures gaskets seal properly after reassembly so you don’t trade an E2 for uneven baking later.
Good habits that keep E2 away
A little preventative care goes a long way. Wipe the oven after heavy roasts and bakes, especially around the rear shroud where grease mist settles. Don’t pack pans right up against the fan cover—leave a bit of space so air can circulate. Use cookware sized to the rack, not oversized sheets that block airflow. And avoid chronic overloading; if the fan spends every dinner service fighting a blocked path, the motor ages faster and bearings run hotter.
E2 is your oven’s way of saying “I’m not breathing right.” Sometimes it’s a quick clean-and-go; sometimes it’s a fan motor or control board that needs attention. Start with a reset and a careful visual clean, listen to how the fan behaves, and if the code sticks around, bring in a pro to protect the appliance and get performance back to normal.
