We have a jacuzzi/whirlpool hot tub off our deck. Last December it did not turn on one day so I called the pool company and they came out and changed a fuse.. The fuse was $6.00 the home vist another $100.00. Yesterday I went to put some bromide in and it did not turn on again. We have had a bunch of thunderstorms so I am thinking it may be a fuse again. I hate to pay an extra $100.00 if I could change the fuse myself but don't know how to tell which is the bad one?
