Why do lake fountain or pond aerator overloads trip?
Overloads are used to protect your lake fountain or pond aerator motor from higher than normal running current. They can trip even on a motor that is in good running condition.
A couple of common reasons for overloads to trip are if you experience a power surge or sag in power or if a pump becomes cluttered with debris. Once the problem is corrected and power is off you can reset overloads by pressing the reset button(s). Some reset buttons will have a need to be pressed firmly until an audible click is heard.
