Digital control panel for Alde 3010

atlasb

We have noticed multiple times (about 4) that we see a yellowish flash appear on our Alde control panel.  It has happened at random times and with the display lit or timed out but on.  Not sure what causes it and have a call into Spencer at Alde but have not gotten to talk with him just yet.  It catches your eye when it happens and everything else seems to be functioning.  This appeared once this last week when we were out.  Noticed it sever other times last season.  This is in our 2018 400.  Has any one else noticed this happen?  Seems to happen when we are heating the cabin.
