Unico fan question

Hi all,



Looked at a customers heat pump the other day. They told me every once in a while they would have to "hit" the control box to have the blower shut off. It has a variable speed control on the side that is adjustable and three relays inside.

Anyone run into that before? Of course it would not fail while I was there, normal for those situations.



Thanks for any insight!

    Unico.....

    The last time I installed a Unico Air Handler, There was a TD for the blower.  Not sure if this applies to other models, but everything should be in the manual or wiring manual.  You stated that it stops by someone banging on the unit or something to that affect.  Let us know what you find.......
