LOL! I was wondering what the hell an E was doing on a fuse...I turned it around so it now reads "3".
Wish I could use the blonde excuse for that one...
Anyway, yea...I pulled it out and it's intact.
Looks like this is the extent of my diy, since I don't have a volt meter. Any recommendation of where to buy these transformers, in the event that's what the problem is? I have a contract with an HVAC company that I pay a monthly payment to, but honestly, they're a rip off (charged me $300 to spend 20 minutes to replace a $60 part before) so I'll probably have them troubleshoot it, but handle the repair and/or find the part myself.
