Is my food safe if I see Er rF?

Check the fresh food temperature with a fridge thermometer. If it rises above normal fridge temperatures for several hours, move perishable food to a cooler or another fridge until the fan is fixed.

Why does the Er rF code come back after I reset the fridge?

A reset or defrost can clear ice for a while. If the code returns, the fan motor may be failing, or something is causing frost to keep building up, such as a door seal or defrost problem.

LG Refrigerator Er rF Error Code

Refrigerator

Applies to: All digital display models (especially dual-evaporator French Door). May also appear as E rF, rF.

What's going on

Er rF on an LG refrigerator means the fan that moves cold air through the fresh food section is not spinning the way the control board expects. Most often the fan is blocked by ice or the fan motor has worn out. Start with a few simple checks, then plan on replacing the fan motor if the code keeps coming back.

Your refrigerator uses a small fan to push cold air from the cooling coils into the fresh food section. The control board watches the fan's speed. If the fan stops or runs too slowly, the board shows Er rF.

This code can appear on LG models with a digital display. It is especially common on French door models that have a separate cooling system for the fresh food section. Codes can differ between model generations, so confirm the meaning with your model number.

The code matters because without this fan, the fresh food section can warm up even though the freezer may still feel cold. Food can spoil if the problem is left alone.

Likely causes

refrigerator evaporator fan motor — The fan motor can wear out, get noisy, or stop spinning. It can also get stuck when ice builds up around the blade.
evaporator cover — This cover sits in front of the cooling coils and fan. If frost builds up behind it, or it is cracked or out of place, it can block the fan or let ice form around it.
main control board — The board powers the fan and reads its speed. A fault on the board can cause the code even when the fan itself is fine.

The same code can mean different things on different model generations. Check the model number on your refrigerator's rating plate before ordering parts.

Can you fix it yourself?

Doable for an experienced DIYer with the right part, but many people still call a technician.

Safe things to check first

Listen near the back wall inside the fresh food section with the door closed and the light switch pressed. A quiet hum with no airflow, or a ticking or scraping sound, points to a blocked or failing fan.
Look at the back wall and air vents inside the fresh food section. Move any food or containers that are pressed against the vents.
Check that the doors close and seal fully. A door left slightly open lets moist air in, which can cause frost to build up around the fan.
Power-cycle the refrigerator by unplugging it or switching off its breaker for a few minutes, then turn it back on. If ice is suspected, a longer power-off with the doors open may let it melt. Move food to a cooler first, and put towels down to catch water. Always unplug the refrigerator or switch off its breaker before touching anything inside it.

When to call a technician

A handy owner can often replace the fan motor with the correct part for their model. Call a qualified appliance technician if the code returns after a reset and defrost, if ice keeps coming back, or if a new fan does not clear the code, since that can point to a defrost or control board problem.
