Awning Motor

There's no transformer that I can see. For a transformer to be required, the voltage required by the motor would be less or more than the motor required, no? In this case the motor takes 110v directly.
I found the relays at Mouser $4.65 each. On the board this is the only area that looks like it got zapped. Think I should get them?

Erm, no? ;D

Well, I always thought that a transformer changed the voltage either steping it up or lowering the voltage. In this case, why would a transformer be needed if the end componant requires the same voltage going in? Not trying to be a smartass just trying to learn. :)
Anyway I do not believe that this unit has one, I've seen what transfromers look like and there's no room in the housing for one. The mains power would come in to the unit and hit the transformer first right? In this unit the mains power goes directly to the board.
I think I'm going to take a chance and order the relays. I think only one is blown but I'll replace both.

Oh, the power comes into the board and it looks like the relays are the first thing it hits.
If you look at picture three, you can see where the mains hit the board.
Also if you look at the bottom left of the picture, you can see some white plastic gearing. I believe that this is the limit adjustment. There is a magnet that gets turned when a ring on the outside of the housing gets turned. What does one call this hall effect?
ChadTower:
Actually, I was being a smartass, because the grammar makes that statement really, really awkward.
Yes, the transformer is for either stepping voltage up or stepping voltage down. If the motor works on pure 110v then you may not need one. I'm betting that the controller PCB does not work off 110v.
