What it means
A6 means the indoor blower motor is not operating or reporting normally. Filters are safe to check, but the motor, feedback wiring, and board are technician work.
Urgency
advisory
This is not usually an immediate safety hazard, but do not keep resetting it. Try the safe homeowner check below; if the code comes back, schedule service.
Likely causes
- Indoor/outdoor communication wiring or terminal problem
- Loose low-voltage connector after service or vibration
- Power interruption during the control handshake
- Indoor or outdoor control board fault after wiring is verified
Homeowner fix
Turn the unit off, clean the indoor filter, and check only for visible blockage at the return or outlet. Restart once; if the blower is noisy, stuck, or A6 returns, stop troubleshooting.
When to call a pro
Call a licensed HVAC technician if A6 returns or the indoor blower does not run normally. Tell them the code is indoor fan motor related.
This code points to electrical or inverter work - get repair quotes from contractors in your area.

This is normally repairable, but it is not a homeowner repair. If the unit is older, out of warranty, or a technician quotes a major compressor, inverter, board, or sealed-system repair, compare the quote with replacement.
