Furrion Refrigerator: “E3”
warning RV refrigerator error codes
What it means
Freezer-compartment temperature sensor fault: the temperature sensor (thermistor) in the freezer is reading out of range or has failed (open/short), so the controller cannot regulate freezer temperature correctly.
Most likely causes
- Failed or out-of-range freezer thermistor/temperature sensor most likely
- Disconnected or corroded sensor wiring/connector common
- Sensor iced over / affected by heavy frost less common
- Control board sensor input fault rare
Safe checks you can do yourself
- Note whether the freezer is running too warm, too cold, or cycling oddly, which is consistent with a bad sensor.
- Power down and check for frost/ice around the sensor area in the freezer.
- Perform the hard reset (remove shore, battery, and solar power) to see if it was a transient read.
How to reset / clear E3
- Disconnect shore power, 12V battery, and solar to the fridge.
- Wait a few minutes and reconnect all power.
- Restart and check whether E3 clears.
When to call a technician
The code persists after a reset and basic checks — the freezer thermistor or board typically needs to be tested/replaced by a technician.

Note: Definition from the official FCR11DCGTA manual. Some Furrion 12V models map a refrigerator-side sensor to a different label (e.g. E13 on the FCR11), so verify which compartment sensor the code names on your exact model.
