LG LSEL6335F RF knob controls LF element

Brand: LG
Model Number: LSEL6335F
Main Symptom: RF knob controls LF element and LF element stays on High when LF knob is on Low
What happens & when: Both Issues are intermittent but both issues happen at the same time.

  • For the element staying in High when knob is set to low I am certain it is the infinite switch that is bad

Error Code (if any): None
Parts or tests already tried: None

Based on the information provided, it sounds like the left front infinite switch has a fused contact on the L2 side. Replacing the switch should fix both issues. Here is a link to the switch that would be used for the front left. EBF62174907 Rotary Switch (Selector) | Genuine Lg OEM In Stock

Thank you for the response, just ordered the part. Will update once it arrives.

Part was delivered next day and it fixed the problem, wanted to wait a week to make sure the problem is gone for good. Thank you!
