Indicator light on for only 3 seconds at a time
I got a 38 gallon from petco which came with this heater as part of the deal. The filter and everything else works great. We followed the instructions for the heater carefully but the indicator light for the heater only went on for 3 seconds then off. It kept doing it every 10 min (on for 3 seconds then off). Water temperature did not change for over 12 hours now. Is the heater defective or is this normal?
