I have just received this replacement board. How do I set the three pots on this board after installing it?
Are you referring to where the wires go?
Hello, My garage door is opening but is not closing, Can you help remedy this issue?
This could be an issue with the safe-t-beams. For assistance please contact customer service at 1.800.354.3643.
Hello, Chadwick Here again , I did the check on the safe t beam units ,everything seems to be ok with both of them, green light and red light are on steady no interruption with the beam. What I should have explained is that, we had a spike in electricity Saturday and after that is when the door wasn't closing. So my conclusion is that the main board may have gotten damaged in that spike. I'm speculating her I may be wrong.
That could be correct, or it still could be something else. Will the door close if you press and hold the wall console in?
My unit only closes if you press and hold the interior button down for the whole cycle ? nothing from the remotes Is the board going bad? Model ISD995
I have an Excelerator Model ISD990 and I get 2 blinks showing a problem of Controller Board Interrupt. I have unplugged it as directed and plugged it back in and it works for a sequence or two and stops again. Does this sound like I need a control board replacement?
Yes it does sound like the control board would need to be replaced. If you would like to troubleshoot with our tech support, you can contact them at 1-800-354-3643 for assistance.
I have an ISD990. Motor jumps a bit but no drive shaft or carriage movement. No status blinks except an on and off when remote pressed. Unplugged and replugged. Suggestions?
If the motor is running but the screw drive is not turning, that sounds like the coupler could be stripped. But if the motor is not running (but just trying to start) that could be a few things. For troubleshooting assistance, please contact Genie customer service at 1-800-354-3643.
I am trying to replace the circuit board for a Genie Excelerator, model ISD990; would I need to order this board: Control Board 36600R.S. It does not look exactly what I am trying to replace.
Yes, the 36600R.S would be the circuit boards for the ISD990. It may appear to look a little different than the old circuit board.
