After a bit of googling I wasn't able to find anyone sharing my issue. My heater's light flickers in a strange way. I'm not sure if it's a calibration issue or what, but the heater is still functioning as far as I can tell. Here is a link to a short vid which somewhat shows the issue in a crappy fashion https://vid.me/Lx0U, but might be enough to help you guys help me. Thanks.
