Error code U5?

Back to List

I have a day old sentinel HD55S and a couple times when it turns off it has beeped and flashed "U5" then goes off until it comes back on again. As I type this it turned off and did not beep or flash "U5." Only thing I did different since was raise the humidity to 57 from 55.

Any ideas???

Hi Google,

U5 is the version number, which is only displayed for about 2 seconds when the machine is turned on. If the situation described above occurs, the motherboard is defective and must be replaced.
