Hello there,I've got a morgan newport spa and the motor continues to run even though temp is met.Has original controls.1997.I've replaced pressure switch and adj.I manually opened contacts to pump low solenoid pulled them back together pump runs.I pulled curcuit board out and checked for any burning found none.Thanks for your help!

It is possible that your system is set to run 24/7, although if you have owned this spa since 97 then that is un-likely as you would already know that. the other possibility is that if you have a mechanical time clock on this unit then it may have gone bad and gotten stuck closed or someone could have changed it to never turn off...Otherwise there may be some sort of hi-limit trip and the system is trying to cool down by keeping the water flowing, but the most likely cause for all this is a bad circuit board.
