Hello! Well, I'm about to take off my RSM250 hood and disassemble it as I have two lights out, a third light that is dimmed, and one hood fan that I can see that is out (I'm not sure if other hood fans are out as I really can't see the other two clearly and the two is the back are working fine).
It has been decades since I changed out a ballast on a tank and frankly I don't remember it being particularly difficult, but I am feeling apprehensive about tearing apart the hood today.
I did some online searches for info and vids, not so helpful. I went to the Red Sea website download center looking for manuals/instructions and found a manual on changing hood fans, but not changing ballasts (yet). I'm looking for trouble shooting, decision tree, or steps in determining issues. I found a diagnostic chart. I think that is as close to trouble shooting as I can get. I'm pretty sure there is a ballast issue with the two bulbs b/c the same bulbs moved to other locations work and brand new bulbs in the location where the previous bulbs weren't working, aren't working there either. But, I'm not sure what is going on with the third dimmed bulb. And I don't know if there are any connections between the fans and the ballast.
I have bought one new ballast replacement and four fan replacements.
The diagrams in the manual are helpful, but still a little confused on how it is all connected. With transformers and fuses and other stuff, just want to make sure that since I have the hood off and open that I replace all that may need it.
Any idea about the third bulb dimming? Perhaps an indication a second ballast is on its way out? Anything else I should be looking for?
And are the fans and lights at all connected through a ballast or fuse or anything else?
Thanks!!
