Hi - hoping to find some expert guidance - not very handy with electrical. Pool light worked great until the end of last season. Bulb started to flicker, and eventually stopped working. Dropped the pool level, replaced the bulb. However, no fan no light. The fuse is good (tested with a multimeter for continuity) - I can’t seem to find any GFCIs around the pool area that are tripped - lights around the pool are working etc. I have toggled the switches up/down and have a remote for this unit, with no luck. There is a mains box in the pool shed pictured, I have everything up. how do I check to see if the unit is getting power?any other typical issues I can look for? I love the light when it worked. Thanks
