Furrion Refrigerator: “E4”

warning RV refrigerator error codes

Safety The compressor housing can exceed 175°F (about 80°C) in operation — do not touch it. The sealed system uses flammable R600a (isobutane) refrigerant; never puncture tubing or attempt a recharge, and keep open flames away. Disconnect power before any inspection.

What it means

Compressor fault: the compressor is reported stuck/not starting, or the system pressure is too high for it to run. The controller stops the compressor to protect it.

Most likely causes

Compressor cannot start (locked rotor) or repeatedly trips out common
High system pressure, often from poor ventilation/airflow around the cooling unit or a very hot install location common
Low supply voltage preventing a clean compressor start common
Failing compressor or compressor inverter/control board less common

Safe checks you can do yourself

Confirm the rear/vent area is not blocked and the fridge is not in an unusually hot space; improve airflow if needed.
Check that house-battery voltage is healthy and stays up under load.
Let the unit sit powered off for several minutes (pressures equalize), then do the hard reset and restart.
Make sure the fridge is roughly level so the compressor and refrigerant behave normally.

How to reset / clear E4

Disconnect shore power, 12V battery, and solar.
Leave it off several minutes so internal pressures equalize.
Reconnect all power and restart; check whether E4 clears.

When to call a technician

E4 persists after improving ventilation, confirming good voltage, and resetting — the compressor or inverter board likely needs professional diagnosis/replacement.
