The two leads are different parts.
True’s product references identify 810719 as a wide-profile gasket and 810803 as a narrow GDM-49/T-49 gasket. Treat these as candidates to investigate, not a choice based only on the T-49 label.
| Part reference | Listed design | Parts Town listed dimensions |
|---|---|---|
| 810719 → | Wide profile | 53 5/8 × 26 1/8 in. |
| 810803 → | Narrow profile | 54 1/8 × 25 5/8 in. |
Read the individual part pages for manufacturer and merchant references. Similar outside dimensions do not establish the same profile or attachment method.
Production history changes the answer.
The merchant-hosted 810719 compatibility document lists T-49-HC use before August 26, 2017. Its legacy T-49 notes include an approximate late-2005 production change, factory-specific conditions, and special serial exceptions. Do not apply the HC cutoff to every T-49.

This guide does not turn a production date into a guaranteed-fit decision. A serial-specific lookup is still needed, including confirmation of any changed door assembly or superseded number.
Bring these details to the supplier.
- 01
Copy the entire cabinet model and serial from the identification plate. Preserve HC, F, and other suffixes exactly.
- 02
Record any existing gasket part number and take clear photos of the corner, mounting profile, and door assembly.
- 03
Ask how to measure the gasket. Do not compare a centerline measurement with another supplier’s outside dimensions.
- 04
Have True or the supplier resolve the applicable number and quantity before ordering. A parts-list appearance is useful evidence, not a serial-fit result.
Using the equipment library
Our current equipment data includes T-49-HC and T-49F-HC. It does not contain a separately verified legacy T-49 specification record. Keep those identities separate during a replacement-parts search.
