LG Range (Electric) F36 error code
The F36 error means your LG range detected a problem with a transistor — an electronic switching component in the range's power control circuitry. Transistors regulate and control the electrical current flowing to the cooking elements. When one fails the range cannot control power delivery correctly and stops the function. A circuit breaker reset clears it in some cases but if F36 keeps returning the faulty transistor or control board will need to be inspected and replaced by a technician.
Common causes
- Transistor in the power control circuit has malfunctioned or failed
- Power surge caused damage to the transistor
- Control board component failure affecting the transistor circuit
How to fix it
-
1
Turn off the circuit breaker for the range and wait 30 seconds
-
2
Turn the circuit breaker back on and check if the error has cleared
-
3
If F36 persists after resetting the transistor or control board needs inspection and replacement by a qualified technician

F36 error — frequently asked questions
What does the F36 error mean on a LG range (electric)?
A transistor fault was detected
What causes the F36 error?
The F36 error is usually caused by: Transistor in the power control circuit has malfunctioned or failed; Power surge caused damage to the transistor; Control board component failure affecting the transistor circuit.
Can I fix the F36 error myself?
This is rated a hard fix — it often requires tools, parts, or experience, and may be safer left to a professional technician.
How much does it cost to fix the F36 error?
Fixing the F36 error on a LG range (electric) typically costs $100–$350, depending on parts and whether you do it yourself or hire a technician.
Is it safe to keep using my range (electric) with the F36 error?
We'd recommend addressing the F36 error before continuing to use the range (electric), since hard-rated issues often involve a real fault rather than a minor glitch.
