On the LREL6325 the surface elements are radiant elements under the glass, switched by knobs that click at OFF, HI and LO, plus a Warm Zone at back center. LG's troubleshooting says an element that does not work needs the breaker checked and the correct knob set for that element; one that will not hold a rolling boil usually has the wrong cookware or low house voltage, so cover the pan. Elements cycling on and off to hold the setting is normal, and an element that stops glowing after you turn it down is still hot.
Differential
Likely causes of “LG range or oven electric or radiant burner will not heat correctly”, and how to tell them apart
- 1
The knob is not pushed in and turned to the right element
What separates it The element you want stays cold while another one heats
How to confirm Push the knob in, turn it in the correct direction and check the glow
- 2
A dual or triple element used in single mode
What separates it Only the inner ring of the left front element heats when you expect the whole element
How to confirm Turn the knob clockwise to use the outer element, as LG describes
- 3
Cookware that does not match the element
What separates it Water will not reach a rolling boil even on the highest setting with a lid on
How to confirm Use flat pans that match the element diameter and cover with a lid
- 4
A tripped breaker or low house voltage
What separates it No element heats at all, or every element seems weak compared with before
How to confirm Reset the range breaker and try a lid to reach heat
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which element does not heat and what its knob is set to
- Whether the oven works when the cooktop does not
- The knob position and what the indicator shows
Try in this order
0 of 5 completedCheck the knob
ReversiblePush the knob in first, then turn it to a setting. LG says the control clicks at OFF, HI and LO.
Use the right element mode
ReversibleOn the dual element turn the knob counterclockwise for the inner ring or clockwise for both rings; a triple element has a third position.
Check the pan
ReversibleLG recommends flat, heavy-gauge pans matching the element size with tight lids; pans should extend no more than 1/2 to 1 inch beyond the ring.
Check power
ReversibleReset the range breaker and check the house fuse; LG lists both as causes of elements that do not work.
Use the Warm Zone correctly
ReversibleFor the back-center Warm Zone press COOKTOP Set/Off, then use the Level button; it is for keeping cooked food hot for up to 2 hours, not for cooking.
Model-specific
What is true of this model and not of its siblings
- Cooktop elements
- Single elements click at OFF, HI and LO. The left front is a dual element (turn the knob counterclockwise for single, clockwise for dual) and some models add a triple. The hot-surface light stays on until the glass cools to about 150 °F.
- Warm Zone
- Press COOKTOP Set/Off; the warm zone light flashes, then use Level. Start with hot food only, never for more than 2 hours. It does not glow red.

Stop boundary
When this stops being a self-service repair
- !If no element glows on any setting after a breaker reset, call an electrician or LG service
- !If glass is cracked, stop using the cooktop and call service, because spills can reach the wiring
