Daikin Mini-Split Code 00

Status

Normal. 00 is what the remote shows in service-check mode when the system has no stored error. If you go through the code-retrieval procedure and land on 00 with a long beep, the control is not reporting a fault.

Manual wording: “System 00 Normal”

Documented for: All Daikin residential ductless with wireless remote service-check mode

Likely causes, most common first

  1. No fault stored in the control
  2. The problem is intermittent and cleared itself
  3. The complaint is a comfort or airflow issue rather than a control fault

What you can safely check yourself

  • Check the remote is in the mode and temperature you expect
  • Check and replace the indoor unit air filter
  • Make sure supply and return airflow at the indoor unit is not blocked by furniture or curtains
  • Check the outdoor unit is clear of leaves, snow and debris

When to call a technician

If comfort is poor but no code is stored, a technician needs to check refrigerant charge and airflow with gauges - there is nothing further a homeowner can read off the remote.

A Daikin mini-split throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
