Product Identity

The Google Nest 3rd Gen T3021US is a mirror black replacement bezel designed for the third-generation Nest Learning Thermostat. It serves as the outer cosmetic ring that frames the device display. The part ships without the thermostat base, display unit, or any wiring.

Compatibility Scope

This bezel fits the T3007ES stainless steel model and other third-generation units sharing the same chassis. It will not fit first-generation, second-generation, or Nest Thermostat E models. Buyers needing a complete thermostat or internal components should look elsewhere.

Deciding Specification

The part number T3021US confirms this is the mirror black finish for third-generation hardware only. Verify your thermostat model against the T3007ES listing before ordering to ensure the ring matches your device.

Questions about this item

Will the mirror-black finish on the T3021US bezel scratch or fade, and can I replace just the ring again later?

The T3021US is a snap-on outer ring only; if the mirror coating wears, you can remove and swap the ring without touching the thermostat base or wiring.

Does the T3021US bezel block any of the thermostat's built-in Wi-Fi or voice-control sensors?

The replacement ring is shaped to fit the 3rd Generation chassis precisely, leaving the microphone, speaker and antenna areas fully exposed for normal operation.

Will the metal-look bezel get hot or affect the thermostat's temperature readings when the heating runs all day?

The outer ring sits outside the sensor chamber and draws no power, so it stays at room temperature and does not influence the internal temperature measurement.
