Questions & AnswersAsk a Question
Would this circuit board work for model IS550/A? The circuit board number on my opener is 31180A - R1. I just want to be sure that the replacement part 36521R.S will work with my opener model.
Yes, this will work.
How many devices( keyless entry's or transmitters ) can you program to this reciever
You can program up to seven wireless devices.
Will this work on model #CM8600IC/A
Yes, it will.
will this board work on H4000A

I’m looking for the circuit board on the genie H6000A which has the learning button
This is the one, the 36521R.S.
Will this part work with my ISL 950/A
Yes, it will.
My defective receiver circuit board # is 33286B-R0 for a Genie ISL 950/A. Is the 36521R.S replacement part the correct receiver board for the ISL 950/A?
Yes, it is!
It appears that my Genie Pro 98 does not have a learning mode... will this board work in that unit and give it learning capability so I can install an exterior keypad and synch?
No, you would need to add an external receiver model GIRUD- 1T for that capability.
My is850 is missing learning button. Is this part needed to repair and how does it install?
This receiver board will have the learn code button on it. So if your learn code button is missing or not working, this would resolve that issue. The installation instructions will come with the new board 36521R.S. You can also view the instructions in the tab below on this page for installation instructions. https://store.geniecompany.com/products/intellicode-receiver-board-for-ac-screw-drive-garage-door-opener
will this work with ISD990?
No, this is not the correct circuit board for the ISD990. You would need the 36600R.S circuit board.
