I have a Samsung Free Joint 3 room Heat/AC split system 4

Customer Question

I have a Samsung Free Joint 3 room Heat/AC split system 4 years old. The manual calls it either a MH050FX A2 or a MH080FX A4
All 3 units will not heat when turned on. They all start to operated then quickly turn themselves off and all 3 lights on the unit flash.
I have checked the fuses and they appear to be okay. I have also turned on and off the breakers.
The manuals say nothing about all three lights flashing.
What can be done?

Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! That means there is a problem with the Option Code programmed into the indoor control. How long did you leave power off to the indoor unit? If less than 4 hours, try again and see if it will reset.
