LSDS6338F
LG LSDS6338F Slide-In Range for Dual Fuel Repair

Most common issues on this model
- Gas burner ignition when a burner will not light
- UltraHeat dual burner when the flame is uneven
- Electric oven elements and sensor when baking is off
- LED knob lighting when a knob stays dark
- ProBake fan when results are uneven
The LSDS6338F is a dual fuel slide-in range, with the power of a gas cooktop and an electric oven. It has a brass UltraHeat 22K BTU dual burner, white LED knobs that light when a burner is on, ProBake Convection, and air fry and air sous vide modes.
Gas and electric parts are serviced separately here. On the cooktop, we clean the ports, check the cap and test the spark on a burner that will not light, then examine the dual burner’s inner and outer flames. If a knob does not light while the burner is on, we test the LED and the connection behind the knob.
The oven is serviced like any electric oven: elements, sensor, fan and control, and we use a reference thermometer for modes that hold low temperatures. Parts are matched to the model and serial on the label, and you approve a written price before work begins.

Error codes this model can show
My LSDS6338F burner flame looks uneven. What next?
On a dual burner, the inner and outer rings each need open ports. We clean them, check the cap seating and test the spark, then compare the flame to the other burners.
A knob on this range no longer lights up. Is the burner affected?
Not necessarily. The LED and the burner are on separate paths. We test the knob light and its connection, and confirm the burner works before quoting.
Can you service both the gas and electric sides in one visit?
Usually yes. We test both, and the price is written down before we replace any part. A part that has to be ordered may need a return visit.
