H71 time plan: 5–15 minutes for the H71 owner-level check; professional control, communication, or configuration diagnosis commonly takes 30–90 minutes.

H71 parts decision: H71 points to DC cooling fan inside the control board abnormality, but it does not prove a control board is defective. The keypanel, harness, supply, firmware/configuration, and exact board revision must be separated by diagnosis.
What not to do
- Do not spray the controls, hold random key combinations, repeat resets, open the console, or order a control board from H71 alone
- Do not run an extra test cycle after the source tells you to stop or arrange service for H71
Preventive maintenance
- 1Follow the exact Panasonic maintenance schedule for the air conditioner and keep the model, serial number, and service history available
- 2If H71 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
