Wow...that was a great save! Wouldn't have thought to swap those and it took me a few reads and looks to figure it out.

So, just to verify what I'm reading...

The #3 circuit on the TM-200 #1 blew so...since the #2 unit only uses the "#1 position", you used it and put the the failed TM-200 where only the "#1 position" is needed?

Brilliant...and and unexpected backup!

Do we dare ask if you can even get those modules and at what price?  (Hope it's not like Carefree's modules!)

Thanks!

Steve, yes, all correct.  The Silverleaf TM-200 is available $375 and I did order one.  I figure that I spend a lot of time where 4 A/C units are required so why not carry one more spare part.

One thing I need to do when at my shop is clean the rust off of the A/C rooftop units electrical connections, compressor especially as well as capacitors and also check the evaporator water pump motors.  They are the same motors used in bath fans, swamp cooler motors, etc..  I have lots of experience replacing them.  I have never had good success repairing them, must be something to do with the steel rod going through the brass bushing, I don't know.
