Hi,
I just acquired our first hot tub, a 2001 Hot Spring Vanguard, which is in need of work. The previous owner was pretty straightforward about the issues, but was unsure of what was actually required to get the tub back into action.
As he described it, one (he didn't remember which) of the breakers in the sub panel started to trip every once in a while, then it became more frequent, and finally, both breakers tripped and, upon resetting, no anything... none of the lights on the motherboard light up.
Along the way, the Heater Relay as been replaced, once pretty recently (so it is the newer, more robust relay), the main Circuit board(at east once, also not a real long time ago), and he said he replaced the heater at least once.
So far, I have:
*verified that the wiring is correct
*verified that the GFCI breakers are functioning
*verified voltage to the heater relay
*verified that voltage is making it to the black tab and red tab on the heater relay
*verified voltage to the red tab and black tab on the motherboard.
*visually inspected both the heater relay and motherboard. The heater relay looked brand new -- no scorch marks anywhere.
The motherboard also looked to be in good condition, with no scorching anywhere on the back, no soot, etc. I did notice that a small chip in the middle looked like it might have gotten hot. The telephone style plug for the ozonator also looked a little fried, and pieces of it came off when I pulled it out. And the yellow "block" towards the upper left looked like it may have gotten hot, but it was not melted...
Other than that, I am stumped. Is there a way to verify whether or not the motherboard is fried?
Any help will be greatly appreciated!
Thanks,
David
