Hello,

I'm on my FOURTH MCB for my Horizon Fitness T25. The last 3 have flamed on me. I have a question about the "cube next to the speed cube"... But first let me ask this..

Horizon keeps sending me boards that have the 2.0HP box checked on the circuit board... My motor is the 1.75HP motor... Is this the proper MCB for my model? They keep sending SJED08011DG.

2nd... During my last calibration test, the tech from Horizon had me messing with the cube next to the speed cube (sorry, i don't know it's official name)... Anyway, he had me jack it up to the max (turned all the way clockwise) and it caused the board to flame and basically it exploded... thought my house was going to burn down..... How SHOULD that cube be properly tuned?

Any help would be GREATLY appreciated!!
