KitchenAid Refrigerator 13E Error: Preserva Humidity Sensor
What Does KitchenAid Refrigerator Error Code 13E Mean? 13E on a KitchenAid Preserva refrigerator indicates the Preserva humidity sensor has failed. The Preserva system is a KitchenAid feature that manages humidity in the fresh food compartment to extend produce life. When the humidity sensor can no longer be read, 13E is set and the Preserva-specific […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. General refrigerator operation is not affected. Only the Preserva-specific produce management is disabled until repair.
Can I reset the code?
No. A power reset does not repair a failed sensor. 13E returns on the next read cycle.
When to stop immediately?
Stop if you notice: 13E alongside general refrigerator temperature alarms, Produce rapidly spoiling beyond normal rates.
Symptoms You May Notice
Produce wilting or sweating in the Preserva drawer
Fruit and vegetables in the Preserva-managed compartment are either wilting (too dry) or showing condensation on their skins (too wet) because humidity can no longer be regulated properly.
13E displayed on control panel
The error code appears on the display. General refrigerator cooling and temperature are unaffected.
Preserva indicator lights abnormal
The dedicated Preserva status indicator is off, blinking, or showing an unusual pattern — the system has disabled the Preserva-specific features until the sensor is repaired.
Possible Causes
Preserva humidity sensor failed
The humidity sensor inside the Preserva compartment has failed after long-term exposure to the variable humidity environment. Electrolyte or membrane degradation is the typical mechanism.
Requires ProfessionalSensor harness broken inside the drawer area
The wiring to the humidity sensor has broken, usually from the repeated motion of opening and closing the Preserva drawer assembly.
Requires ProfessionalControl board Preserva input channel
The analog input on the main control board that reads the humidity sensor channel has failed. Produces the same reading pattern as a sensor fault.
Requires ProfessionalSafe Checks You Can Do
-
1
Use the Preserva drawer as a regular crisper
Until service is completed, use the affected drawer as you would any regular produce drawer. Do not expect the Preserva humidity benefits but the drawer still provides basic cold storage.
Consume or move delicate produce within a few days of the fault appearing — without Preserva, shelf life drops closer to standard refrigerator storage times.

Schedule service when convenient
13E is not urgent and does not compromise food safety. Schedule service when convenient for a Preserva system repair.
Tell the technician specifically that it is 13E Preserva humidity — this is a less common code than standard F codes and requires the right replacement part.
When to Call a Professional
Contact a qualified technician if:
- Preserva humidity sensor replacement clears the fault
- Drawer harness continuity tests open
- Control board input channel verified bad
