Universal replacement boards for modern furnaces
I'm trying to stock the right stuff in our inventory, any service gurus out there? What units do you keep on your truck?
Recently we used the W-R 50A55-843 with success. I'm hoping someone can chime in and save me some time studying the ins and outs.
We have the HW S8610U and the HWS9200U as well.
Thanks for any comments
