Product perfect fit and great match, however blew this transformer too before figuring out the problem being a wire was connected to new thermostat that shouldn't have been. It shouldn't have even been connected on the furnance when installed!!

Fixed noise 11/09/2014
By Bert
Used to replaced noisy/buzzing transformer. Old was loose at the blade connector attached to the body. I quessed causing vibration as cycling voltage is present all the time. Fixed the noise problem. Iam not electrician but easy install.

Snow Storm 02/16/2015
By james allen
Xformer worked great, we were without heat for three nights without it! Burned a lot of wood!
Ordered on Sunday PM and received on Wed. late, normally 2nd day air would have been Tuesday!
But understand your storm conditions.
