I have what I believe to be a gatsby hot tub circa 93 from what I can see form the labels. Problem is the element is working but only when I hold it closed via a non conductor like a stick. Even on the low pressure timed warm up the relay for the element is not closing. I have basic electronic knowledge and ohmed the thermostat normally open and closed positions it seems to open and close properly on the normally open side but not on the normally closed side? The timer works element works pump works both high and low pressure. I'm not getting any voltage to the red wire that is attached to the side of the relay? Should I be? Could it be a bad pressure switch on the housing pipe for the element? Any help would be great thank u
