I need to replace my Chamberlain AccessMaster garage door opener logic board. The part # is 41A5021-1H-315. I'm having trouble finding that part, but I get lots of results for part # 41A5021-1M-315. They look similar. Can one be used in lieu of another?

Maybe, maybe not. Contact Chamberlain customer service and ask them, they'd be better equipped to help you.

I went to their website. Both part #s refer to the same part. I got the new logic board (the one listed with the different part #), installed it, and it worked.

Send an inquiry either by means of a phone call or email to their customer service dept. A lot of companies have tech assistants that may be able to answer your question. All we can do is speculate.

Thanks, but I was able to confirm via their website that both part #s refer to the same part. I've since replaced the part and everything works fine now.
