How to Replace the Heating Element on a LG DLE3400W Dryer — Step-by-Step Instructions
Step-by-step instructions for the LG DLE3400W (electric dryer). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
ELECTRIC DRYERS ONLY — this guide is not for gas burners. Unplug the dryer; a 240V circuit is unforgiving. Confirm zero continuity assumptions with a multimeter, not guesses. If your dryer is GAS, stop here and use a pro.
Tools
- Nut driver / socket set
- Multimeter
- Shop vac
- Phone camera
Parts
- Heating element (or element kit with thermostats/fuse) for your model
Step by step
-
1 Test before you buy
Unplug, open the rear or lower access panel, and put a multimeter across the element terminals: around 8–15 ohms = good element (look elsewhere); infinite/open = burned out.
-
2 Photograph the wiring
Two or three spade terminals plus thermostat wires — one photo saves twenty minutes of head-scratching later.
-
3 Remove the element housing
On most designs the element lives in a metal can beside or behind the drum: remove the mounting screws, disconnect the terminals, and slide the housing out.
-
4 Swap the element
Transfer the element into the housing (or swap the whole can if your kit includes it), being careful not to nick the new coil — it’s fragile before its first heat cycle.
-
5 Replace the guards while you’re in there
If your kit includes the thermal fuse, hi-limit, and cycling thermostat, install them — a shorted element often weakens them, and they’re $10 parts sitting right next to it.
-
6 Vacuum, reassemble, and test
Shop-vac every lint drift you can see (this is why the element died), reconnect per your photo, close up, and run a timed-dry cycle: heat within a minute, no burning smell after the first dust burn-off.
LG DLE3400W notes & error codes
The Flow Sense duct test is genuinely useful — take D-codes seriously before they become a blown thermal cutoff. nP after a storm is usually the breaker, not the dryer.
| Code | What it means |
|---|---|
| D80 / D90 / D95 | Duct blocked 80/90/95% — clean vent now |
| tE1 / tE2 | Thermistor faults |
| nP | No power on one 240V leg — check breaker |
| CL | Child lock on (not a fault) |
Full details for this machine — common problems, causes, and costs — are in the LG DLE3400W repair guide. The general version of these instructions is here.
A new element that dies quickly means an airflow problem is cooking it — if your vent run is long, on a roof, or you can’t find the restriction, get a pro with a vent rig before buying element number three. If you'd rather skip it entirely, find a dryer repair pro near you →
