Aquarium Submersible

Aquarium Submersible
Tetra Submersible Heater broken?

I bought a Tetra Submersible Heater (30-60 gallons) at Walmart for my 38-Gallon Aquarium. The box says that there is an indicator bright red when the heater is on. However, the red light goes on on and off, on and off. I wonder if it is broken and if I return it. I tried to convert the NOB for heat, but if I put the arrow goes off. Help? And by turning on and off, on and off, I mean every minute or so it turns off and back on, and so on. Not every hour or so.

Monitor your water temperature to be sure, but it seems to work well. That is normal for heat to go in and out of that. If your temperature is not Wack, then you know that is the heater.
