LG Er rF on a refrigerator: fridge fan not working properly
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
LG says rF appears when the fridge compartment fan motor does not operate normally. Unplug the fridge or switch off its breaker, wait about 5 minutes and use it again. If rF repeats, LG asks for a technician to check it.
Safety first
Stop and check this first
- Do not remove inner panels to look at the fan: there is wiring behind them connected to the board. If rF repeats, LG asks for a technician. Meanwhile, keep an eye on the food.
Safe checks you can perform
- 5 minute reset
- Food temperature
- Cooling in each compartment

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Fridge fan diagnosis
What they doThe LG technician unplugs the fridge and checks the fan motor, its wiring and the board signal.
They must show youwhether the motor turns and receives power.
In writingthe cause, the reference of the replaced part and the reason.
Cooling test after the repair
What they doAfter the repair, the fridge is left running and the technician confirms the compartment cools and rF does not return.
They must show youthe temperature falling and the panel without the code.
In writingthe test result.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

5 minute reset
No special tools
Procedure
- Who:
- you.
- How:
- unplug the fridge or switch off its breaker, wait about 5 minutes and restore power, as LG instructs.
- Result that matters:
- rF does not return.
- If it does not return:
- it was a one-off glitch; note the date.
- If it returns with the same symptom:
- LG asks for an LG technician to check it.
- Evidence to keep:
- a photo of the code and the date of the reset.

Food temperature
No special tools
Procedure
- Who:
- you.
- How:
- put an appliance thermometer in the fridge and another in the freezer, and keep the doors closed while you see whether the fan works again.
- Result that matters:
- the CDC sets 40 °F (about 4 °C) or below in the fridge and 0 °F (about -18 °C) or below in the freezer.
- If the readings are within range:
- the food is still protected; check the thermometers again every few hours.
- If the fridge is above 40 °F:
- with the door closed, the CDC gives the fridge 4 hours at most and a full freezer 48 hours (24 if half full). Frozen food that still has ice crystals or is at 40 °F or below can be refrozen. When in doubt, throw it out without tasting it.
- Evidence to keep:
- a photo of each thermometer with the time and a list of what you threw away.

Cooling in each compartment
No special tools
Procedure
- Who:
- you.
- How:
- compare the fridge and freezer temperatures with the thermometer.
- Result that matters:
- knowing whether only the fridge compartment is warming, the one that depends on this fan according to LG.
- If only the fridge is warm:
- it fits rF; mention it when you request service.
- If both are warm:
- there is a bigger cooling problem; ask for an urgent visit.
- Evidence to keep:
- readings from both compartments with the time.

What it means
LG explains that rF means the fridge compartment fan motor does not operate normally. That fan circulates cold air inside the fridge, so the compartment can warm up even if the freezer stays cold. LG's step is a reset: unplug or switch off the breaker and use it again after about 5 minutes. If the same symptom and code repeat, LG says an LG technician should check it for an accurate diagnosis. The code does not say whether the motor, its wiring or the control is at fault.
Warnings and stop conditions
- Mediumeditorial warning
