I got my Yoder YS640 in July of 2014. Well on 1/15/16 I had my first problem, imagine that a pellet pooper smoker/grill 18 months with no problems. I fired it up and the controller just went nuts reading all kinds of weird temps and not controlling. I e-mailed All Things BBQ where I bought my rig the next day which was a Saturday. I gave them a very detailed description off what was happening with my grill. I didn't expect an e-mail back on the weekend, But a couple of hours later got a very nice e-mail from them stating that my grill was defiantly still under warranty and that they had forwarded my e-mail to Yoder customer support. First thing Monday morning I received an e-mail from Yoder that gave me exact how-to instructions, with pictures, on how to help them trouble shoot my problem. It took me about 45 min. to follow there instructions, then I e-mailed them the results. 10 min. later I got an email from Yoder stating that they had a new thermo couple on its way to me and that should fix my problem. That Monday was Martin Luther King day so I know they would not mail it until Tuesday at the earliest. I received my package on Saturday with detailed instructions, with pictures on how to do the repair, I installed the new part, put it all back together, fired it up and just as they said my unit was fixed.
IMHO That is a perfect customer service experience.
I am happy to say that "I AM A MEMBER OF THE YODER FAMILY!!"
