On the covered LG range or oven, F6, F19 means an Upper Oven Heating Error — LG's own wording. First, note whether the upper oven reached any heat at all. Then: for F6 and F19 LG says to press CLEAR/OFF and run the oven function again, and, if the code returns, to switch the breaker off for half a minute before switching it on — LG's own sequence.
Differential
Likely causes of “LG range or oven code F6, F19”, and how to tell them apart
- 1
A worn or burnt bake element
What separates it The oven never reaches the set temperature and the bake element does not glow orange
How to confirm Look at the bake element with the oven on: a cold element, a blister or a break points to the element
- 2
A broil element that has failed
What separates it Broiling is weak or the upper element stays dark
How to confirm Switch to Broil and watch whether the upper element glows
- 3
A weak oven sensor reading
What separates it The oven overshoots or undershoots and then shows the code
How to confirm A technician can compare the sensor's resistance with LG's service table
- 4
A relay on the electronic control that no longer closes
What separates it No heat and no click when the oven calls for heat
How to confirm Listen for the relay click at the start of a bake
- 5
A loose or burnt connection at the element terminals
What separates it Heat comes and goes, sometimes with a smell
How to confirm Look for discolored terminals with the power off at the breaker
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the code is F6, F9 or F19, since LG words all three as heating errors
- How long the oven takes to reach 350 degrees and where it stops
- Whether the bake or the broil element glows
- Whether the code appeared during self-clean
Try in this order
0 of 9 completedWhat to do first
ReversibleNote whether the upper oven reached any heat at all.
Correct only the documented fault domain
ReversibleFor F6 and F19 LG says to press CLEAR/OFF and run the oven function again, and, if the code returns, to switch the breaker off for half a minute before switching it on — LG's own sequence.
Note the shortfall
ReversibleRecord whether the oven heats at all, and which element is cold, so the technician can match the heating fault.
Run the reset LG gives
ReversiblePress CLEAR/OFF and try again; if the code returns, turn the breaker off for 30 seconds and back on.
Preheat and time it
ReversibleSet 350 degrees and note how long it takes and whether it stops short; a shortfall points to heat, not a display fault.
Watch the elements
ReversibleWith the oven on, check whether the bake element glows evenly; an element with a dark patch or a blister is failing.
Test with a thermometer
ReversibleAn oven thermometer in the center rack shows whether the real temperature follows the display.
Check what else heats
ReversibleIf the broil element works and the bake element does not, the fault is in one circuit, not the control.
Write down the pattern
ReversibleRecord the code, the function and the time to reach temperature before you call service.
Model-specific
What is true of this model and not of its siblings
- Aliases on this page
- F6, F9 and F19 are all LG's own wording for an oven heating error.
- Parts involved
- Bake element, broil element, oven sensor and the heating relay on the control.
- What LG says
- LG's own list gives the CLEAR/OFF and breaker reset, then service if the code returns.
Stop boundary
When this stops being a self-service repair
- !Do not use the oven if it overheats or does not shut off
- !Switch the oven off at the breaker if you smell burning or see sparks at an element terminal
- !If the code returns after LG's breaker reset, book service through LG's Request a Repair page with the model number and the exact code
- !Do not bypass a limit or sensor to keep the oven working

Exact questions
Common questions
What does F6, F19 mean on a LG range or oven?+
an Upper Oven Heating Error — LG's own wording.
Can I keep using the cooktop?+
Cooktop use is separate; turn the oven off at the breaker if it misbehaves.
Is the heating error the same whichever of its three codes my display shows?+
LG words all three as oven heating errors, so they share this page; which one appears depends on the cavity and model.
Why did my oven show a heating error after a self-clean?+
Self-clean runs the oven very hot, and an element or sensor that was marginal can fail during it.
Is it the control board?+
Less often than an element or sensor; a technician rules out the cheaper parts first.
Does the reset fix it?+
It clears a one-off glitch; a code that returns right away means a part has failed.
