I wanted to get warm, so I got myself into the kotatsu. But it seems like it's not getting warm at all and the heater isn't
I turned the temperature setting to "strong" and I also touched the heater to see if it's on. But it's not getting any warmer. I thought maybe our kotatsu broke down and then I realized something. I realized the main switch of the kotatsu wasn't on at all! My NG switch is "ON" as usual.
