Hi do you have any insights on my problem involving 115 emc..
Size is 45 inches but the maximum movement of backgauge is only limited to 29 inches only.
You press the manual button foward and will always limit at 29 inches, but still too far away to the forward limit switch.
Forward limit switch is responding on board.
Even the keypad input is up to 29 only. Entering more than 29 errors it.
Theres no problem on the automatic and manual movement within the 29 inches.
Calibration movement can go up to the forward limit 45". but after finding the reference point at 24" you still cant move beyond 29.
I already replaced HK and AR board but no avail. Also checked the voltages are within threshold, and the glass encoder is clean.
 
Please check this, see if it helps
