Error help

I cleaned ibts and when I plug back in I get err with just err and 300 which is my preheat setting. Nothing works

I just started up with faceplate off and was able to get going. I suspect there is too much tension on grey wire going to display. What should i do. Taking faceplate off and cleaning might be to much for that short grey cable.

Please send photos of which cable you refer to and if you have errors please copy the error log from RoasTime

When you put the faceplate back on be very careful that the cable doesn’t get pinched between the faceplate and the roaster.
