Lg wkex200hwa dryer not heating — new installation · np

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Photograph the complete display before clearing it, including the exact lower-case nP, and record the model suffix from the rating label. Note that the drum turns, the cycle starts, and no heat is felt, but do not run repeated test cycles.

   Expected result: The display is exactly nP on WKEX200HWA, a different code appears, or the model is actually the gas WKGX201HWA or another platform.

   Next step: Use the exact model and complete code when contacting the installer or service. Keep the dryer off while the code or model identity is uncertain.

   Stop if: Do not clear the evidence by cycling power repeatedly or substitute another LG model's code table.

   Why this matters

   Why: Only the exact nP entry supports LG's no-current-at-the-heater path. A different code or platform needs its own LG guide and cannot be diagnosed from this article.

2. Check 2

   From a dry, safe position, look at the power cord, plug, outlet face, and dryer breaker without opening any cover or touching wiring. Check for looseness, scorching, moisture, a hot plug or outlet, physical damage, or a breaker that will not stay on.

   Expected result: The accessible connection looks intact and cool, or there is heat, damage, moisture, arcing evidence, or a repeated breaker trip.

   Next step: If any hazard or repeated trip is present, leave the dryer off and contact an electrician or emergency service as appropriate. If no hazard is present, give the observations to the installer rather than opening the terminal area.

   Stop if: Do not touch exposed conductors, remove the rear terminal cover, measure voltage, or continue after smoke, sparks, burning odor, or a hot outlet.

   Why this matters

   Why: An intact exterior does not prove correct voltage or internal connection; a visible hazard makes this an immediate stop-use condition. LG requires a licensed electrician to verify the outlet when nP is present.

3. Check 3

   Only if the plug, outlet face, cord, and surrounding floor are dry and show no heat or damage, switch the dryer breaker fully OFF for at least 10 seconds and then restore it once, as LG documents for nP. Do not remove the plug repeatedly or reset a breaker that trips again.

   Expected result: The breaker will not reset, immediately trips, nP clears but heat is still absent, or the dryer heats normally after the one reset.

   Next step: Record the result and stop testing. For a new installation, have the installer verify the circuit and power-cord installation; if the installation is already accepted, arrange a licensed-electrician and/or LG service assessment.

   Stop if: Do not repeat the reset, change breakers, use an adapter or extension cord, or perform live voltage/current tests.

   Why this matters

   Why: A successful reset can clear a breaker state but does not prove the circuit can safely deliver the dryer load. A trip, recurring nP, or continued no-heat condition requires electrical or appliance service.

4. Check 4

   Contact the installer with the exact model WKEX200HWA, the nP photograph, the installation date, whether the drum motor runs, and the accessible plug/breaker observations. Ask the installer to verify the power-cord installation and wall outlet; do not attempt to correct wire order or circuit configuration yourself.

   Expected result: The problem began on the first use, the installer has not checked the circuit, or the installer confirms the outlet and cord installation are correct but nP remains.

   Next step: Keep the dryer off and request a written installation/electrical finding. If the external supply is verified, arrange LG or qualified appliance service for the persistent nP/no-heat symptom.

   Stop if: Do not authorize rewiring, terminal-block work, circuit changes, or component replacement based only on the nP code.

   Why this matters

   Why: LG specifically routes a just-installed nP case back to the installer for the power-cord and outlet check. A confirmed external supply does not prove a particular internal dryer part; it only moves the case to qualified appliance diagnosis.

5. Check 5

   Prepare a service record with the complete nP code, exact model suffix, serial information, install date, whether the drum spins, whether any heat was ever produced, breaker behavior, cord/outlet observations, and any odor or visible damage. Do not disassemble the WashTower to obtain more evidence.

   Expected result: nP returns after the documented external check, the dryer still spins without heat, the supply is confirmed, or any electrical hazard appears.

   Next step: Arrange qualified LG appliance service after a safe external supply is confirmed, or qualified electrical service when the outlet/circuit is uncertain. Keep the unit off until the responsible professional clears it.

   Stop if: Do not open the cabinet, access the terminal block, bypass a safety device, make live measurements, or continue operating a hot, damaged, sparking, or repeatedly tripping dryer.

   Why this matters

   Why: The unresolved path may be in the dryer heater-current circuit or control path, but the code and symptom do not identify a heater, fuse, board, or wiring component. A hazard overrides normal diagnosis.
