Pros & Cons
👍 Pros
- Genuine OEM LG part ensures dimensional accuracy — correct diameter, weight, and glass grade for the compatible 25-liter platform
- Drop-in replacement with no modification required on compatible models
- OEM glass composition is rated for the full power output and temperature range of the original microwave
- Individual part replacement restores microwave function without requiring a full appliance replacement
- Part number MJS63771901 provides an unambiguous reference for confirming compatibility via LG's parts lookup
👎 Cons
- Compatibility is limited to specific LG 25-liter models — not a universal fit, and requires model number verification before purchase
- Sold as tray only — the turntable ring/support roller is not included, and a damaged ring will require a separate part order
- Glass trays are inherently fragile during shipping; inspect for cracks or chips immediately upon delivery
- No installation hardware or instructions are included beyond the basic part — most users will not need them, but the manual reference requirement assumes you have access to your original documentation
- Only available as a genuine LG part through authorized channels — pricing may exceed aftermarket alternatives for users where exact OEM specification is not a priority
Frequently Asked Questions
What microwave models is the LG MJS63771901 glass tray compatible with?
LG designates this tray as compatible with 25-liter LG microwave ovens. Because LG produces multiple 25-liter models with different interior dimensions, you must verify your specific model number against LG's compatibility list or your owner's manual before ordering — tray diameter is the critical fitment dimension.
Is this an OEM part or an aftermarket replacement?
This is a genuine OEM LG replacement part, manufactured to the same specification as the tray originally installed in the microwave. OEM glass trays maintain the correct diameter, weight balance, and glass composition for proper rotation on the factory turntable ring.
How do I confirm the correct tray size before purchasing?
Measure the diameter of your existing tray, or locate your microwave's model number (typically on a label inside the door frame) and cross-reference it with LG's parts documentation. Do not rely solely on the 25-liter capacity designation — interior cavity geometry varies between models at the same capacity.
Can this tray be used in microwaves from other brands?
This tray is manufactured to LG's specifications and is not guaranteed to fit non-LG microwave ovens. Even if the diameter appears close, glass tray compatibility depends on the turntable coupler geometry and rotation ring diameter — these dimensions vary by manufacturer and model family.
Is the replacement tray safe to use with all standard microwave functions, including high power and steam?
Yes. As an OEM part, the MJS63771901 is manufactured from microwave-safe glass to the same specification as the original. It is rated for the full power range and functions of the compatible LG microwave models it is designed for.
