    sundance sentry 724 heater help

    I have a Sundance sentry 724 hot tub, yes I know it's a little outdated but I cant afford to buy a new one. Anyway, the heater on this baby stopped working for me a little while ago and I have been pulling out my hair trying to get it up and running again. I replaced the heater and the pressure...
