Zettler AZ762-1A-12DE relay for nearly every Balboa circuit board ever made for the European market.

Some common faults with elderly Balboa boards are sticking relays, either on or off.

This can sometimes manifest itself in such instances as the Blower staying on (you cannot turn it off no matter what you do) or the Heater sticking on (and the spa continuing to heat no matter what you do)

We sell these relays as an exact replacement BUT you are on your own with regard to having the relay fitted to the circuit board.

We cannot accept any responsibility for any damage or the end result of it's fitting which may not cure the fault on your board.

You should seek a professional electrical engineer to remove the old relay and solder in this new one, but considering the money saved versus a new board it should be well worth the effort.
