Panasonic Air Conditioner F87 error code

Difficulty: Medium · Cost: $0–$200 · Duration: 15–20m

The F87 error means your Panasonic air conditioner's control box overheat protection has activated — the temperature inside the outdoor control box has exceeded the safe operating limit. This protective shutdown prevents heat damage to the electronics. The most common cause is poor ventilation around the outdoor unit. Ensuring adequate airflow around the outdoor unit and clearing any obstructions usually resolves it.

Common causes

  • Outdoor unit is installed in a poorly ventilated enclosed space trapping heat
  • Objects or vegetation are placed too close to the outdoor unit blocking airflow
  • Outdoor unit cooling fan is running slowly or has stopped
  • Ambient temperature is extremely high

How to fix it

  1. 1

    Turn off the unit and check that the outdoor unit has adequate clearance on all sides for airflow

  2. 2

    Remove any objects, vegetation, or debris blocking airflow around the outdoor unit

  3. 3

    Allow the control box to cool down for 15–20 minutes before restarting

  4. 4

    If F87 keeps returning contact a qualified technician to inspect the outdoor unit fan and control box
