Direct answer
For the LG WashTower WKEX200H dryer section, prove both breaker poles for electric models, the outlet and control wake state before internal service. First, reset the correct breaker once and verify the receptacle safely.
What this covers
- LG WashTower WKEX200H dryer section (WKEX200H*)
- Stacked WashTower; this record covers the dryer section and shared controls.
- The specific fault this record addresses: has no power or a blank display
What it does not cover
- ×The same symptom on a different LG product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
A tripped breaker, including only one leg on a 240V electric dryer
What separates it Complete darkness on the display for a fully powerless report; for an electric dryer where the display and light still work but nothing heats, see not-heating instead — that's a partial, not total, power loss.
How to confirm Check the breaker panel for both poles of a double-pole breaker; reset once and observe whether it holds or trips again immediately.
- 2
The outlet or cord itself has failed
What separates it The breaker tests fine but the outlet shows no power to a test device, or the cord shows visible damage.
How to confirm Test the outlet with a known-working device before assuming the dryer's internal supply has failed.
- 3
An internal control board or transformer fault
What separates it Confirmed good power at the outlet and breaker, cord undamaged, and still no response at all from the unit.
How to confirm This conclusion is reached only after external power sources are ruled out, and is a technician diagnosis.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the display, light and every function are dark, versus some functions working and only heat or one specific feature missing.
- Breaker panel state for both poles, on an electric model.
- Whether a breaker reset holds or trips again immediately.
Test the receptacle with a known-working device
ReversibleConfirms whether the wall outlet itself has power before touching the breaker panel.
Reset the correct breaker once
ReversibleFor electric dryers, check both poles of the double-pole breaker specifically.
Inspect the cord and plug externally for damage
ReversibleDo this with the dryer unplugged.
Arrange internal service if external power is confirmed good
ReversibleA control board or transformer fault is a technician diagnosis at that point.
Run one empty cycle to confirm stable power with no flicker or loss
ReversibleConfirms the fix rather than a momentary reconnection.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- WKEX200H*. Stacked WashTower; this record covers the dryer section and shared controls.
- Type — WashTower DRYER section (stacked, shared panel)
- This is the DRYER half of the LG WashTower — an electric vented dryer stacked above the washer, sharing ONE center control panel with it. A control/power fault can affect both halves, and a centrally shown code may belong to the washer or the dryer, so identify the dryer section first.
- Fuel — ELECTRIC (vented)
- ELECTRIC vented on 240V. No heat with the drum turning is often a half-tripped double breaker; reset both halves. It has an exhaust vent that must be kept clear.
- Venting & features
- Clogged lint screen or blocked duct is the top cause of long drying. Sensor Dry and ThinQ Wi-Fi; the dryer's lint filter is easy-reach on the WashTower's center panel design.
- Symptom boundary
- This record covers LG WashTower WKEX200H dryer section when it has no power or a blank display. A different symptom on the same hardware, or this symptom on a different LG product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Unplug and do not reset a breaker more than once if it trips immediately again — that indicates a short, and repeated resets risk fire or further electrical damage.
- !A hot plug, visible arcing, or a damaged cord means stop immediately and do not use that outlet or cord again until replaced.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. LG publishes this as "[LG Dryer power] The power turns off during use, or there is no power supply". LG's own dryer no-power article: house breaker, the 4-wire cord and the terminal block. Found by rebuilding LG's 4,660-URL help-library list from its own sitemap (docs/verification/lists/lg-help-library.txt); the earlier list had been kept in a session scratch directory and was gone. Probed 2026-08-23: title-verified. What that article does not carry is the model boundary — it is written for a product line, and WKEX200H* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
The dryer on my LG WashTower isn't heating but the washer works.+
The WashTower's washer and dryer are independent machines sharing one panel, so the dryer can fail while the washer is fine. Treat the dryer on its own: reset the 240V double breaker (a half-trip leaves the drum turning with no heat), and clean the lint filter and exhaust vent. If a code shows on the shared display, check whether it is a dryer or washer code. The washer below is unaffected by the dryer's heat problem.
My electric dryer has no power at all — not even the light.+
Check both poles of the double-pole breaker in the panel. If only one side had tripped, the display and light might still work off partial power — full darkness on everything points to both legs being out, or the outlet/cord itself.
The breaker keeps tripping every time I reset it.+
Don't keep resetting it — a breaker that trips again immediately (rather than holding) points to a genuine short circuit, which is an electrician or appliance-technician diagnosis, not something to force past by repeated resets.
Does this answer apply to every LG model?+
No. It is scoped to WKEX200H*. Stacked WashTower; this record covers the dryer section and shared controls.
What should I record before troubleshooting no power or blank display?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing no power, blank display. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Unplug for heat, arcing, cord damage or repeated trips.
