SCS 2702 basement air rebuild - whited44 - 08-03-2026

As many of you know I’ve been fighting with my large SCS 2702 unit. Well I’m rebuilding it!!

I removed it, undercoating and rust proofing the compartment bay, put a stainless sheet on the floor of the bay.

Put the unit itself on saw horses.  It just got a new board at newell but the outside fan motor crapped out.  I’m replacing both fan motors, and all of the capacitors.  

I’ll add some pictures with where I’m at now and as progress goes.

Capacitor numbers
Titan POCF15A
Titan POCF45A
Cera-mite 305C20

Fan motors 
Outside Dayton 3LU77
Inside Dayton 4M098

Nice work Dennis! You will be happy when you are putting it back in! Yours is looking pretty dirty and crusty, thankfully mine were fairly clean. 

I thought about doing this to mine while I had them out but they really looked in great shape so I decided to risk it. So far so good.

FYI, on the capacitors, getting the same exact manufacturer and model can be difficult sometimes. Main thing is to match up the mfd rating and voltage rating. Mfd is microfarad btw, usually represented by a script letter uf.
