Furrion Arctic 8 and 10 5 Flashes: Thermal Fault
5 FLASHES
Furrion Arctic 8 and 10 5 Flashes: Thermal Fault
The system shut down because it got too hot, from a hot RV or from working too hard with poor airflow.
Before you start
- Hot RV? Furrion’s test starts with the room under 90°F.
- Airflow matters. Air goes in the left side of the front vent and out the right side.
Fits these models
The Furrion Arctic 8 cu ft (FCR08DCGTA) and 10 cu ft (FCR10DCGTA) 12V compressor refrigerators, in every door finish and hinge side. The second number under each model is its Lippert part number.
How to read this code
5 flashes, then a pause. The Arctic has no display. This code comes from the inverter board on the compressor, and you read it with a small test LED.
- Disconnect power, slide the fridge out and take off the back cover. The inverter board is on the compressor; its terminals are labeled −, +, F+, F−, D, C, P, T.
- Connect the LED’s negative leg (cathode, the flat edge) to terminal D. Nothing else is plugged in there.
- Connect the positive leg (anode) to the + terminal without unplugging its wire: slide the rubber sleeve back and clip onto the metal connector.
- Reconnect power and wait at least 5 minutes. Count the flashes before each pause.
You need a 10 mA LED and alligator clips or a spade-terminal jumper. No flashes? Recheck the connections, then see the intermittent-operation flowchart.
STEP 1
Let it cool down
Make sure it’s under 90°F in the RV. Turn the fridge off and disconnect power for at least 2 hours, then reconnect and restart.
Does the code come right back?
Replace the inverter board and the cooling fan
Cooling fan: Lippert part 2021124043 (also supplied as 2023004446 or 2023004447). Ask a tech and we’ll track one down.
Furrion Control Board Kit 2021149633 →Genuine OEM inverter board (C-FCR10DCGTA-006). Fits every Arctic 8 and 10.STEP 2
Clean and clear the airflow
Clean the fan, condenser coils, air channels and front vent cover of dust, hair and anything blocking them. Reinstall it in the cabinet and confirm it cools.
Keep it from coming back
Don’t run the fridge while it’s stored or closed up: that traps heat and causes thermal lockouts. Follow the storage steps in your owner’s manual.
Still stuck? ask a tech with your model, serial number and the readings you got. We’ll confirm the part before you order.
