What to do if the Toshiba MMY-MAP1004T8P-SG indoor remote controller is not accepted and a check code is displayed?
- M
  Ms. Patricia BlackAug 7, 2025
  If the indoor remote controller isn't working and a check code appears on the interface PC board of the header unit, the issue might stem from unset addresses or incorrect power settings. Start by setting up the addresses for the line and indoor units. If you're using group control, make sure a group address is set up. Also, confirm that the indoor unit power is turned on, ensuring you power on the indoor units before the outdoor units. Finally, check that the indoor/outdoor communication line is correctly connected to the U1/U2 terminal of the header unit.

What to do if my Toshiba Air Conditioner is not accepting operation from the indoor remote controller?

  john70Aug 16, 2025
  If your Toshiba Air Conditioner indoor unit isn't responding to the remote controller and there's no check code on the header unit's interface PC board, the problem likely lies in the communication wiring or address settings. First, check the communication line between the indoor and outdoor units and modify the wiring if necessary. Next, ensure that both the line address and indoor address are correctly set for the unit that's not responding. If you are using indoor group control, make sure that the power of the header unit of the group is turned on. If the unit is under individual control, verify that the group address is set to “0”. Finally, confirm that the power is turned on for the unit and that the indoor remote controller is properly wired.

Why does my Toshiba MMY-MAP1004T8P-SG display a lower number of connected units after address setup?
- T
  Theresa AndersonAug 27, 2025
  If you're encountering a situation where a lower number of connected units is displayed after address setup, it might be due to miswiring or unconnected wires in the communication lines. * For outdoor units, check the communication lines between them. If you find any issues, correct the wiring, set up the addresses again, and then verify the number of connected outdoor units. * Similarly, inspect the communication lines between indoor units. Correct any miswiring, set up the addresses again, and check the number of connected indoor units. Also, verify the wiring of the indoor remote controller.
