Bertazzoni French-Door Refrigerator Code EH: Humidity Sensor Error

What EH means

On Bertazzoni French-door refrigerators including the REF36FDFZXNT, REF36FDFIXNV and RFD36FZNX, EH means the humidity sensor has a problem. The REF36FDFZXNT reports the sensor as failed, with the code shown in locked mode and an alarm chime that any button silences. On the other platforms the unit still cools, and the sensor only supports humidity control. It does not affect whether the compartments are cold.

Common causes of EH

A humidity sensor with an open or shorted reading
A damaged wire or loose plug at the humidity sensor
Moisture or frost on the sensor
A control board input that cannot read the sensor

✓ One safe check you can try

1. Press any button to stop the chime. 2. Check the crisper area for standing water and wipe it dry. 3. Make sure the doors close fully so moist room air does not enter. 4. Restart the appliance at the breaker after one minute. 5. If EH returns, call us.

! Why to stop there

The humidity sensor sits in the cabinet lining where moisture is expected, and opening it exposes wiring.
A damp connector and a failed sensor look identical from outside.
Repeated breaker resets do not repair a sensor that has lost its reading.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

EHEH questions

Does EH mean my food will spoil?

Not directly. The refrigerator still cools. The humidity sensor helps the control manage moisture, so produce may dry faster or feel damp until it is repaired.

Why does the alarm sound on one model?

The REF36FDFZXNT shows codes in locked mode and sounds a chime. Pressing any button silences it. The other platforms show the code without that behavior.

Is a visit urgent?

No. EH is one of the less urgent messages. Book a convenient time, and we will test the sensor and give a written price before any work.
