I have a SA-9100 that recently goes into protection after about 5 minutes. The light will turn on for about 2 seconds, I'll hear the relay, light turns off for about half a second, and then turns back on again. What's more weird is that I'll turn it off for a couple minutes and when I turn it back on the same thing happens but in longer time intervals 3-4 seconds on, 1 second off. Then the light will stay off another 5 minutes or so, rinse and repeat. Help!
