Toshiba Carrier F06 error code

What it means

The Toshiba Carrier table lists F06 as outdoor temperature sensor TE/TS error. It says an open or short circuit of a heat exchanger temperature sensor has been detected and lists outdoor temperature sensors TE/TS and the outdoor PCB.

Urgency

Likely causes

1. The outdoor TE or TS heat-exchanger sensor circuit is open or shorted
2. The outdoor sensor connector or harness needs service
3. The outdoor PCB sensor input needs service

Homeowner fix

Power cycle once only if you can do that safely. Keep the outdoor cabinet clear of debris, but do not open it.

When to call a pro

Call a licensed HVAC technician if F06 returns. Tell them Toshiba Carrier identifies F06 as outdoor TE/TS temperature sensor error.

Repair vs replace

Outdoor sensor faults are usually repairable. Compare replacement only if the unit is old and major outdoor electronics are also failed.
