Fast, professional LG range repair from technicians who fix LG ranges frequently. Same or next business day on most calls.
Counted from our technicians' notes on 77 LG range service calls.
Most LG gas ovens light with a hot-surface igniter, and it has to get hot enough to open the oven gas valve. Igniters weaken with age. They keep glowing but stop passing enough current, so the oven takes too long to light or never lights at all. The broil burner has a separate igniter. Anything involving the gas valve or regulator is for a technician only.
Constant clicking after a spill or a wipe-down generally means moisture on a spark switch or electrode. Let the cooktop dry completely and check that each burner cap sits flat. One burner that still clicks after drying probably has a bad spark switch on that knob.
A bake or broil element with a blister or split needs replacing. A radiant or coil burner that won't heat, or stays on high, points to its infinite switch in most cases.
F1 or F2 means a look at the oven temperature sensor. F9 says the oven isn't heating the way it should, and that can be an element, an igniter or the control. F3 and unresponsive keys point to the touch pad or control board.
| Code | What it usually means |
|---|---|
| F1, F2 | Oven temperature sensor (thermistor) problem. On double ovens, F4 and F5 are the lower oven |
| F3 | Touch pad or key problem |
| F9 | Oven not heating properly (F19 on some models) |
| F10 | Oven door lock problem. F20 is the lower oven on double ovens |
| F11 | The control boards aren't communicating |
| F7, F17 | Convection fan problem |
| F27 | Self-clean problem. The cooling fan has stopped or seized |
| PF | Power was interrupted |
| H5 | Not an error. The cooktop surface is still hot |
| Sb, 5b | Not an error. Sabbath mode is on |
Codes vary by model. LG's advice for most of these starts simple. Hit Clear/Off and retry. Still there? Kill power at the breaker, wait 30 seconds and restore it. A code that survives both steps means the part behind it needs testing.
Smell gas? Skip all of this. Get out of the house and call your gas utility.
Check along the left side of the oven door opening or the drawer opening, on the bottom drawer frame, or behind the control panel. On double ovens, open the upper door and look under its lip.
Self-clean runs the oven far hotter than any cooking does. LG even has its own code (F27) for the cooling fan quitting during self-clean, and the door lock codes F10 and F20 tend to show up right after a cleaning cycle. If you use self-clean, run it well ahead of a holiday meal, not the day before.
Igniters, elements, spark switches, infinite switches and sensors are routine LG range repairs. A control board costs more, so make sure the diagnosis is solid before ordering one. A damaged glass cooktop is the repair most likely to push you toward a new range.

In our technicians' notes on 77 LG range service calls, the repairs that come up most involve the surface burner or spark switch, bake or broil igniter and bake or broil element. The list near the top of this page shows the rest.
77 LG range repairs are in our service records so far, and customers rated those visits 4.9 out of 5 stars.
On LG ranges, F9 means the oven isn't heating properly. LG wants you to try Clear/Off first. If that doesn't clear it, cut the breaker for 30 seconds before turning it back on. When it comes back anyway, the cause is typically a failed bake element or a weak igniter, and once in a while the temperature sensor or control. A tech can test each part to pin down which one failed.
It's not an error. H5 is LG's hot-surface warning, meaning part of the cooktop is above about 150 degrees Fahrenheit and too hot to touch. It goes away once the surface cools. Still lit on a room-temperature cooktop? LG suggests a 30-second breaker reset, and after that the control needs diagnosis.
F10 is the door locking system error for the upper or single oven, and F20 is the same fault on the lower oven of a double. It tends to appear after self-clean, when the lock motor or switch doesn't release. Try Clear/Off, then a 30-second breaker reset. A door that stays locked, or a code that returns, means the lock assembly or its wiring needs service.
A weakening bake igniter is the most likely reason. It still glows, but it can't draw enough current to open the oven gas valve quickly, so the burner lights late or cycles off. A bad oven temperature sensor or a heavily loaded oven can also slow things down. Replacing an igniter is routine. Leave any gas valve work to a technician.
The trip and diagnostic fee starts at $129. Your technician quotes the repair upfront using the Appliance Blue Book, before any work begins, so you can decide with no surprises.
