I recently went out to check on my hot tub (DreamMaker Eclipse) and found that it was not working. The topside controls were functioning but the pump would not come on. I noticed that I didn't hear any of the relays click when I pressed the buttons. I proceeded to take the control box (Consumer Engineering Inc R400H / LBR400H) out and noticed that it smelled like magic smoke. Once I got it apart it became fairly clear what the issue was. The first relay appeared to switch power on to the other three that controlled pump high/low and heating element. The trace feeding power into this first relay had burned away. I suppose a bad solder joint had deteriorated over time and eventually arced & sparked and finally went open.
After doing some internet research I decided to replace the relay that had the burned pin (AZ2150-1A-15DEF) as well as the the other three (AZ762-1A-12DE). To top it off, there was also a bulged capacitor, TCI brand, 2200uf 35V that needed attention.
I was able to find the exact replacements for the relays and the appropriate Panasonic NHG series cap at onlinecomponents.com.
To help bridge the gap around the burned trace on the main relay, I used a small piece of 14ga copper wire and lots of solder. The tub is now up and running again and hopefully this reconditioned board will work for years to come.
