I was working on a walk in freezer today that had two bad condensor fan motors which I replaced...
I started up the unit and was waiting for the evap fans to kick on ( waited about 30 minutes )
Felt the evap. getting cold but the fans didn't kick on.
I jumped out the Defrost Termination control and the fans started... so i went and picked up a new defrost termination control>
When I got back the freezer was running @ 30 degrees> i put in the new control and started it up> same problem. fans did not start...

really weird senerio.. I need some opinions. would really be helpful. thx!
