When an LG refrigerator stops cooling or a washer shows an error code, you need answers fast. LG appliance repair is not just about swapping parts. It requires correct diagnosis, manufacturer-aligned procedures, and parts that match your model. That is why many Ontario homeowners choose an LG appliance repair service staffed with trained technicians rather than generic handymen.
ARS employs authorized LG appliance technicians who diagnose and repair LG appliances according to manufacturer standards. Whether you need LG refrigerator repair, LG washer repair, or help with a dishwasher that will not drain, this guide explains common failures, what you can check safely at home, and when professional LG appliance service is the right call.

Why Choose Authorized LG Appliance Repair
LG builds complex appliances: linear compressor refrigerators, Direct Drive washers, ThinQ-connected ovens, and multi-sensor dishwashers. Authorized LG appliance repair matters for three reasons.
Correct diagnosis. LG models use proprietary control boards, sensors, and error-code logic. A technician trained on LG systems reads codes accurately and tests the right circuits first. Generic repair shops may misread an LE motor code as a simple belt issue on a Direct Drive unit, leading to unnecessary parts and repeat visits.
Genuine and OEM-compatible parts. Aftermarket parts that do not meet LG specifications can cause repeat failures or void remaining coverage. Authorized workflows use parts sourced through proper supply channels. That matters on linear compressor refrigerators, inverter boards, and ThinQ main control assemblies where compatibility is not optional.
Safety and warranty alignment. Gas ranges, high-voltage dryer components, and sealed refrigeration systems need qualified handling. LG Canada support directs owners to authorized service for in-warranty repairs and provides access to genuine parts catalogues. For out-of-warranty units, ARS provides transparent flat-rate estimates with diagnostic fees credited toward the repair.
If your unit is still under LG warranty, we guide you through the correct manufacturer process. For everything else, our LG appliance repair team handles the full job from diagnosis through completion.
Common LG Appliance Problems
LG appliances are generally reliable, but these issues appear most often in Ontario homes. Winter temperature swings, hard water in many municipalities, and heavy family use all stress washers, dryers, and refrigeration systems.
| Appliance | Common Symptoms | Likely Causes |
|---|---|---|
| Refrigerator | Warm fridge, ice buildup, loud compressor | Linear compressor fault, defrost failure, sealed-system leak, fan motor |
| Washer | OE, UE, LE codes, no spin | Drain pump clog, unbalanced load, door lock, motor or hall sensor |
| Dryer | No heat, long dry times | Heating element, thermal fuse, gas igniter, blocked vent |
| Dishwasher | Standing water, poor cleaning | Drain pump, spray arm clog, inlet valve, heating element |
| Oven/Range | Uneven baking, F codes | Temperature sensor, igniter, control board, convection fan |
For a full error-code reference, see our LG appliance error codes guide. If you are unsure which appliance is failing, note the model number on the door frame or rating plate before calling. That single detail speeds diagnosis.
LG Refrigerator Repair
LG fridges are known for the linear compressor and multi-door designs. Cooling problems are the top reason owners search for LG refrigerator repair.
Not cooling but lights work. Check that the unit is not overfilled and that vents are clear. Food packed against the rear wall blocks airflow and mimics a compressor failure. Listen for the compressor and condenser fan. If the compressor hums but temperatures rise, the inverter board or compressor may be failing. Our guide on linear compressors for LG fridges covers this in detail.
Ice maker issues. Confirm the water supply valve is open and the filter is not overdue for replacement. LG recommends replacing water filters on a regular schedule; a clogged filter reduces flow to the ice maker and can freeze fill tubes on French-door and Door-in-Door models. Frozen fill tubes and faulty ice maker assemblies are common on InstaView and Craft Ice configurations.
Excess frost. A failed defrost heater, defrost thermostat, or defrost control board can cause ice buildup on the evaporator. Do not chip ice off with sharp tools. A forced defrost cycle may clear minor frost, but recurring buildup points to a component failure.
ThinQ and display faults. Smart refrigerators that lose Wi-Fi connectivity or show persistent temperature alarms may have sensor drift or control board communication errors. Power cycling clears temporary glitches; persistent alarms need professional testing.
Proper door seals also affect efficiency. ENERGY STAR Canada notes that well-maintained refrigerators use less energy. A weak gasket forces the compressor to run longer and can mask a larger cooling fault. Run a dollar-bill test: close the door on a bill and pull. If it slides out easily, the seal needs attention.
When cooling does not return after basic checks, book refrigerator repair with an authorized LG technician.
LG Washer Repair
Front-load and top-load LG washers use Direct Drive motors on many models. LG washer repair often starts with an error code displayed on the panel or ThinQ app.
| Code | Issue | Troubleshooting |
|---|---|---|
| OE | Drain error | Clean the drain pump filter behind the small access panel at the front base. Check the drain hose for kinks and confirm the standpipe height meets LG installation specs. If water remains after 10 minutes, the pump impeller, drain motor, or control board may need service. |
| UE | Unbalanced load | Redistribute laundry or reduce load size. Bulky single items like comforters trigger UE on high-efficiency machines. Persistent UE codes with small loads can indicate worn suspension rods, damaged drum bearings, or a failing hall sensor on Direct Drive models. |
| LE | Locked motor | Power off, wait 30 seconds, and restart. If LE returns, the stator, hall sensor, or wiring harness between the motor and main PCB may be faulty. Direct Drive washers do not use traditional belts, so LE codes almost always point to motor-side components. |
| DE | Door error | Confirm the door closes fully and nothing blocks the latch. Inspect the door lock assembly and latch striker. Front-load doors with worn boot seals sometimes fail to trigger the lock switch. |
| IE | Water inlet | Slow or no fill. Check inlet screens and supply valves. |
| FE | Overflow | Overflow risk. Address immediately to prevent flooding. |
TurboWash and Steam cycles add complexity. Steam inlet valves and steam generators on premium models need correct water pressure and descaling over time. See also our post on LG washing machine button errors. For ongoing spin or drain problems, professional washer repair prevents water damage and motor burnout.
LG Dryer Repair
LG dryer repair complaints usually involve heat, airflow, or sensor performance.
Electric dryer not heating. A blown thermal fuse, failed heating element, or faulty thermostat stops heat while the drum still turns. LG electric dryers use multiple thermostats and a high-limit fuse on the heater housing. Testing requires isolating power and checking continuity on each safety device.
Gas dryer not heating. The igniter or gas valve coils are frequent culprits. A weak igniter glows but fails to open the gas valve. Gas appliances should be serviced by qualified technicians who can test gas pressure and flame sensing safely.
Long dry times. Clean the lint screen every load. Inspect the full vent run to the exterior, including elbows behind the dryer. Restricted venting is a fire risk and a common cause of poor drying on LG and other brands. Sensor Dry models rely on moisture sensors near the lint filter; residue on those bars causes premature cycle completion and damp clothes.
Steam and noise issues. Steam dryers need clean inlet lines and periodic descaling in hard water areas. Thumping or scraping often traces to worn drum rollers, a damaged idler pulley, or foreign objects in the blower wheel.
Dryers work harder when washers leave excess moisture in clothes. Keeping both appliances in good condition supports efficiency standards that AHAM documents for Canada and the U.S.
Book dryer repair if heat does not return after lint and vent cleaning.
LG Dishwasher Repair
LG dishwasher repair calls often involve drainage, cleaning performance, or leaks.
Water at the bottom of the tub. Remove and rinse the filter assembly at the tub floor. Check the drain hose high loop under the sink. A failed drain pump, clogged chopper blade, or stuck check valve may need replacement. QuadWash models have multiple spray arms; confirm lower arm rotation is not blocked by a utensil.
Dishes not clean. Confirm hot water at the kitchen tap before starting a cycle. LG dishwashers need incoming water near 120°F for effective cleaning and drying. Clean spray arm holes and use the correct detergent. Hard water areas benefit from rinse aid and periodic citric-acid cleaning cycles. TrueSteam models depend on a functioning steam generator and inlet valve.
Leaks. Inspect door gaskets and the float switch area under the tub. Leaks under the unit can trigger flood protection modes on some models and damage cabinetry. Door leaks on models with third racks often trace to overloading or misaligned upper racks.
Odours and film. Grease buildup in the filter sump causes persistent smells. Remove and scrub the filter weekly in busy households.
For persistent drainage or heating faults, schedule dishwasher repair.
LG Oven and Range Repair
LG ranges include gas, electric, and convection models with digital controls and ThinQ connectivity. LG oven repair covers both built-in wall ovens and freestanding ranges.
Oven not reaching temperature. A weak igniter (gas) or bake element (electric) is a common cause. Gas igniters must reach full glow before the valve opens; a dim igniter cycles heat without ever reaching set temperature. Temperature sensors and control boards also fail over time. ProBake convection models add a third element and fan that must work together for even results.
Error codes on display. F-type codes relate to sensor, ignition, or communication faults. Note the exact code before power cycling. Some codes clear after a single fault event; repeating codes need component-level testing.
Uneven baking. Failed convection fans or incorrect rack placement affect results. Confirm you are not blocking vents with foil. Convection fan motors and elements are separate parts on many LG ranges.
Range top issues. Induction and radiant elements can fail individually while others work. Gas burners with weak flames may have clogged ports or failing igniters at each burner.
Gas odours, repeated ignition failures, or tripped breakers need prompt professional oven and range repair. Do not operate a gas range if you smell unburned gas when all burners are off.
Benefits of Professional LG Appliance Service
DIY fixes work for simple clogs and filter cleaning. Professional LG appliance service makes sense when:
- Error codes return after a reset
- The appliance involves gas, sealed refrigeration, or high voltage
- Water leaks risk floor or cabinet damage
- You need a documented repair for insurance or property management
- Parts must match LG specifications for reliable long-term performance
- ThinQ or smart features fail after firmware updates or power surges
A trained LG appliance technician arrives with diagnostic tools, model-specific knowledge, and access to proper parts. You get a clear estimate before work proceeds, and the diagnostic fee applies toward the repair. That transparency matters when a single misdiagnosed part on a linear compressor or control board can cost hundreds of dollars.
