Space Heater Question
I use space heaters for heat(window unit for cooling). This heater was a Christmas gift last year, so was used only a few months. Started using it this year, and for some reason only 1 of the bricks "glows". This is a picture taken with the setting on HIGH and both bricks should be on/glowing. If I leave it on the HIGH setting, within a few minutes, the whole heater shuts off. If I have it on the LOW setting (one brick), it stays on, but the brick never glows. Any ideas what the problem might be?
