[Duty007]

Hey guys
Looking for some additional information
Got a Samsung AQV18VBE and it’s giving me error code “E458” in heating mode on the indoor unit..Indoor fan operates in cooling mode but not in heating mode,it will give out error E458 after about 15-20 minutes into it’s heating mode.Service manual error description only mentions “E458=fan error”.

Thanks

E458 normally refers to a fault with the outdoor unit fan motor.

Check the fan driver and fan motor following the service manual fault finding guide.
