    How to troubleshoot a Bryant T6?PRH?A display module that doesn't power up?
    • J
      Jennifer GuerreroAug 16, 2025
      If the Bryant Thermostat display module fails to power on after applying power, several checks are recommended. First, verify the presence of 24VAC at the Rc/Rh and C terminals. Next, check the voltage between Vg and V+. Also, ensure that the wiring polarity is correct. Finally, if a red pigtail is wired to Rc or Rh and a black pigtail to C, remove the two-wire pigtail and connect it to the V+ and Vg terminals.
