I have an old Leisure Bay spa. Maybe 15-20 years old? The relay that controls the 5.5kw heater is hanging up in the on position and the spa is constantly overheating. The relay looks like it may have been damaged when the last heater went bad. It looks like it overheated pretty badly at some point. Anyways, the relay itself is pretty typical. It is a Zettler AZ2290-1A-120, but it is hard mounted to a tiny circuit board(just barely bigger than the relay) with a white wire and a pair of red/black wires coming off the board. Red wire brings in 220v to the common on the relay and black wire to heater is connected to NO on relay. I can't find a part number other than the zettler number and I can't find a PCB mounted relay like this anywhere. I'm wondering if I can replace it with a balboa Expander 53426?
