LG LWS3063ST/00 built-in oven Parts

Yes. You can still buy wall ovens, including electric built-in wall ovens like the LG LWS3063ST; they remain a common kitchen appliance category sold in a wide range of sizes, finishes (including stainless steel), and feature sets.

What to consider before you buy

Wall ovens are not one-size-fits-all; the cabinet cutout, electrical supply, and installation method matter as much as features.

• Size and configuration: single vs. double wall oven; measure the cabinet cutout carefully.
• Electrical requirements: wall ovens typically need a dedicated, properly grounded circuit.
• Hardwire installation: this LG wall oven is designed to be direct wired to an approved junction box (not plugged into an outlet).
• Cabinet heat tolerance: surrounding cabinets and wall coverings must tolerate elevated temperatures.
• Mounting and safety: the oven must be secured with mounting screws to prevent tipping or movement.

Installation reality check (what most homeowners miss)

For the LG LWS3063ST, the installation guidance emphasizes hardwiring to a recessed junction box and using the correct conduit connector; it also calls out keeping the side spacers in place so the oven stays centered in the cabinet opening. See the LWS3063ST installation guide.

Quick checklist

Item	What to verify	Why it matters
Cabinet opening	Correct cutout and clearance	Prevents fit issues and overheating
Electrical	Dedicated breaker/fuse sized to the oven’s rating plate	Prevents nuisance trips and wiring overheating
Connection type	Approved junction box, direct wire	Required for this installation style
Securing	Mounting screws installed	Helps prevent the oven from shifting

Why it matters

Choosing the right wall oven is as much about safe fit and proper power as it is about cooking features. Getting the cabinet and electrical details right helps avoid installation delays and performance problems.

You can identify which LG oven you have by matching the model number from the appliance ID label to your paperwork and settings screens. For this Sears PartsDirect page, the model is LG LWS3063ST; confirm your label shows LWS3063ST (sometimes with a suffix like /00).

Where to find the model number on the oven

Most LG built-in wall ovens list the model number on an ID label around the oven frame.

• Open the oven door and check the frame around the oven cavity (often along the side trim or near the hinge area)
• Look for a label that says Model (and usually Serial)
• Write the model number exactly as shown, including any suffix (example: LWS3063ST/00)
• Compare it to your purchase receipt, installation paperwork, or service invoice
• If the label is hard to read, take a clear photo and zoom in

For label locations and model-specific details, use the LWS3063ST owner's manual.

If your oven has smart features

Some LWS3063ST units support LG Smart Oven app features (Tag On and Smart Diagnosis). If your oven and phone support NFC, the app can help with identification and troubleshooting steps referenced in the manual.

• Turn the oven on and check the display behavior during startup
• Look for the Tag On logo area on the appliance (if equipped)
• Use Smart Diagnosis steps in the manual if the oven powers on

Why it matters

The exact model number controls everything from control board compatibility to door hardware fit. For example, parts like the LG range oven temperature sensor EBG61305805 must match the correct model family to avoid temperature errors and improper operation.

LG wall ovens are a solid choice for most kitchens because they typically deliver even baking, useful cooking modes (including convection on many models), and practical maintenance features. For the LG LWS3063ST built-in oven, the LWS3063ST owner's manual highlights EasyClean® and Smart Diagnosis™, which are real quality-of-life features.

What “good” usually means for a wall oven

We judge wall ovens on performance, reliability, and day-to-day usability. Here are the areas where LG wall ovens commonly do well:

• Cooking performance: consistent temperatures and strong broiling on most electric wall ovens
• Convection capability: faster, more even browning when convection is used correctly
• Cleaning options: features like EasyClean® can reduce the need for high-heat cleaning
• Diagnostics: app-based or audible diagnostics can speed up troubleshooting
• Fit and finish: stainless exterior care is straightforward with the right cleaning method

Model-specific features that add value on LWS3063ST

Based on the manual content for this model, these features are built in:

• EasyClean®: a 10-minute, low-temperature cleaning cycle that uses water to loosen light soils
• Self Clean option: for heavier baked-on soils (expect heat and ventilation needs)
• Smart Diagnosis™: helps diagnose and troubleshoot problems using the LG Smart Oven app or call-center process

Quick comparison: EasyClean® vs Self Clean

Feature	EasyClean®	Self Clean
Best for	Light spills, fresh splatters	Heavy, baked-on buildup
Heat level	Low	Very high
Typical experience	Less odor, less smoke	More odor, may smoke; ventilate
Time	About 10 minutes (plus wipe-out)	Longer cycle time

Why it matters

A wall oven is a long-term built-in appliance; “good” is less about flashy features and more about consistent baking results, easy cleaning, and serviceability. When an oven holds temperature accurately and is easier to maintain, you cook more predictably and spend less time troubleshooting.

If performance seems “not good,” check these common culprits

If your LWS3063ST bakes unevenly, runs hot/cold, or throws temperature-related symptoms, these are common areas to inspect:

• Confirm you are using the right rack position and cookware
• Verify convection settings and any auto-conversion options in the settings menu
• Run a basic temperature check with an oven thermometer (after full preheat)
• Inspect the oven sensor circuit if temps swing widely
• Consider the LG range oven temperature sensor EBG61305805 if diagnosis points to a faulty sensor
