Toshiba Carrier F29 error code

What it means

The Toshiba Carrier table lists F29 as indoor unit other PCB error and identifies it as an indoor PCB EEPROM error.

Urgency

Likely causes

1. The indoor PCB EEPROM is not reading normally
2. The indoor control board has an internal memory fault
3. Power or connector issues at the indoor PCB need service

Homeowner fix

Power cycle once if you can do that safely. Do not open the indoor unit or touch the control board.

When to call a pro

Call a licensed HVAC technician if F29 returns. Tell them Toshiba Carrier identifies F29 as indoor PCB EEPROM error.

Repair vs replace

Indoor board repair or replacement can be reasonable on a newer system. Compare replacement if the unit is old and multiple boards are failing.
