An LG washing machine control board replacement usually costs $300-$650, including the part and service labor; some newer or less common models can exceed $700. The LG washing machine control board price depends on the washer model, whether the main or display board is faulty, local labor rates, and how difficult the repair is.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Replacement control board | $120 | $240 | $450 | Part price varies by model and board type |
| Professional labor | $150 | $230 | $350 | May include diagnosis and testing |
| Installed replacement | $300 | $470 | $750 | Typical total before unusual fees |
| DIY part-only repair | $120 | $240 | $450 | Excludes tools and diagnostic costs |
LG washer control board replacement prices by model
For a common front-load or top-load LG washer, an installed main control board typically runs $300-$650. A straightforward repair with an accessible board and a moderately priced part may land near $300-$450; a premium or discontinued model can push the total to $600-$750.
Standalone boards often cost $120-$350, while some model-specific or bundled assemblies cost $350-$450 or more. A display or user-interface board may be priced separately from the main board. Assumptions: U.S. service visit, standard replacement part, normal access, and no additional wiring or component damage.
Budget about $470 for a typical professional replacement, but confirm the board number against the washer’s full model code.
Part, diagnosis, and labor charges in a repair quote
A written estimate should distinguish the board, diagnostic visit, labor, and any additional charges. Some shops credit the diagnostic fee toward the repair; others charge it separately. The ranges below are common planning estimates, not fixed national rates.
| Quote component | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Main control board | $120-$450 | Per board | Model-specific replacement part |
| Diagnosis | $75-$150 | Per visit | Error checks and electrical testing |
| Installation labor | $125-$300 | Per repair | Access, replacement, and operating test |
| Trip or service charge | $0-$100 | Per visit | Travel or minimum service fee |
| Related wiring or connector repair | $30-$180 | Per repair | Only if inspection finds damage |
For labor billed hourly, a technician rate may be $75-$150 per hour, although many appliance services quote a flat repair price instead. A one- to two-hour board replacement can therefore account for a substantial part of the installed price, particularly where the diagnostic visit is not credited.
Ask whether diagnosis, travel, and post-repair testing are included before comparing totals.
Model number, board type, and failure symptoms change the estimate
The exact model code is the strongest parts-price driver. Two LG washers with similar names may use different control boards, and a suffix or production revision can affect compatibility. A main board that manages cycles and motor functions may have a different price from a user-interface board behind the control panel.
Scope also matters. If testing finds a damaged connector, burned wiring, or another failed component, the repair can add roughly $30-$180 for parts and work. A second board or a difficult-to-access assembly may add more. A fault code or a washer that will not start does not prove the board itself is defective; switches, wiring, and power supply problems can create similar symptoms.
Get a diagnosis tied to the full model number and confirmed part number, rather than replacing a board based on symptoms alone.
Reduce the LG washer repair bill without guessing
Provide the service company with the model and serial numbers before booking so it can check part availability and give a more useful estimate. Compare two or three quotes using the same repair scope, including whether the fee covers diagnosis, installation, and testing. A low parts-only quote is not comparable to an installed price.
Before authorizing work, ask whether the board is new, manufacturer-supplied, refurbished, or aftermarket, and what warranty applies. If the washer is still covered by a parts or service plan, check its terms first. Avoid buying a board before diagnosis: an incorrect or nonreturnable part can erase any savings.
The most reliable savings usually come from confirming the fault, avoiding duplicate service fees, and comparing complete installed quotes.
Main board versus display board pricing and repair scope
Replacing one confirmed board is generally less expensive than replacing multiple electronic assemblies. A display board may cost around $100-$300, while a main board often falls around $150-$450; overlap is common because model and availability determine the actual part price. Installed totals can rise if the control panel must be removed or connectors need repair.
Board-level electronic repair may be offered by a specialist for roughly $100-$250, plus removal, installation, and shipping where applicable. It is not available for every board, and a repaired board may have a shorter or different warranty than a new replacement. Compare the total cost and coverage, not just the quoted circuit-board service.
Repairing a board can be a lower-cost option only when the specialist confirms compatibility, turnaround, and warranty in writing.
Three LG control board quote examples by repair scope
A basic example is a standard top-load washer with a confirmed main-board fault: a $180 part, $180 labor, and a $90 diagnostic fee total $450 before tax, assuming the visit fee is not credited. A midrange front-load model might use a $280 board, $220 labor, and a $100 service charge for a $600 estimate.
For a newer model with a costly board and added connector work, a $420 board, $250 labor, $75 diagnosis, and $100 wiring repair would total about $845. That high-scope example is less typical and should prompt a check for other damaged components or a replacement-versus-repair comparison.
These examples show why the part number and included fees matter more than a generic “control board replacement” price.
When an older LG washer may not justify board replacement
Compare the full repair estimate with the washer’s age, condition, and likely remaining service life. A $400-$600 repair may be reasonable for a washer with no other major problems, but becomes harder to justify if it also needs a motor, pump, or suspension repair. A new washer can cost several hundred dollars or more, so the decision depends on the replacement model and delivery or haul-away charges.
Ask the technician whether the board failure appears isolated and whether the replacement part has a warranty. If the quote approaches the cost of a suitable replacement washer, include delivery, installation, and disposal in the comparison rather than comparing the repair only with a new appliance’s shelf price.
Base the decision on the complete repair quote and the washer’s overall condition, not the control board price alone.
