Liftmaster/Chamberlain Genuine Part 41ac050-2 Security and Receiver Logic Board

Started working immediately no issues

Replaced the security receiver board and front piece. Saved me from having to replace the whole motor opener with control board. Had a lift master repairman service rep over earlier and he was trying to get me to spend $750.00 on a new garage opener with motor - as the unit is easily 2007 in the before times. No thank you. The new board and all - Easy to slip connectors on and insert wire sensors into. Worked first time - remotes configured in quickly. Made me feel like a master repairman - like I know what I am doing. Now I am dangerous - next project please.

Arrived on time, well packaged, competitively priced and an OEM and not some cheap knock-off. This part includes the rear panel of the door opener, the light bulb socket, the controller circuit board AND the power supply circuit board w/transformer, instructions, etc. When I diagnosed opener problem, was not 100% convinced it was a controller problem versus weakening/burned out power supply. When item arrived was delighted it contained both boards. Within 30 minutes had door back in operation. Please note: The board comes with the raising/lowering force set to a very light setting. This caused my door to open just fine but in closing, it would go down maybe three feet then reverse. My throat had a lump in it until I calmed down and compared my new board's force settings to the old board. With a minor adjustment (set from 9 o'clock to 1 o'clock), and everything worked beautifully!!!! Thanks Chamberlain and Amazon...

Fixed my problem. No issues

I installed this myself in about 10-15 minutes. I didn't read many reviews before I bought this, as I purchased it after watching a how-to video on YouTube when my garage door opener died, so I had the same misstep as some others. Make sure the blue/purple dials are turned correctly so the force on close is correct. I couldn't figure out why the door wouldn't close, but matching the new dials with the old immediately fixed the issue. It was brand new, packaged well, and arrived quickly. Very happy with this purchase!

Quick shipping so thank you on that ... however these must not be tested prior to shipping or leaving the factory / distributor. What should have been 20 min job turned into 2-1/2 trying to figure out why I could hear a relay click when button or remote was pressed, but no lights or motor (RPM) activated. After double checking and eliminating the button, wiring etc etc I took the units main cover off. Only to discover when pressure was applied to lower part of the Logic Board housing the lights turned on and also activated the motor for a split second. So I applied pressure constantly and all worked. When released from that position all would stop. After trial, error etc etc to figure out why, I found one of the pins on the JST connector form the Logic board to the Power Board was not soldered well. That explains pressure applied the PCB board fixed, the pin made enough contact to work. When no pressure there was not enough contact on the pin to work. I had to break out the soldering iron & solder to make the fix. So frustrating after going without a garage door for 3-4 days and you have what you need right in front of you and then .... NOTHING. I have electronics experience and problem solving mind, so my curiosity put me to work, but I did not budget 2-1/2 hours to get this working. Most would put it back in the box and send it back and wait another 3-4 days for delivery. I went to the sellers website to contact them, but nothing with regards to customer service or support to reply to that I could find. This item is an exact replacement to the original, so that was nice. A defect in manufacturing got me. 5 stars for the replicated part being spot on. I could only give 2 stars due to this not being tested 100% causing hours of work to make it work! Maybe I got the 1 of out 500 that could possible have an issue!!!

My garage door opener had multiple mental disorders. Rather than replace the entire unit for $300 and a ton of labor I thought I'd risk the $90. 15 minutes later working like new. 15 minutes after that all remotes and homelink systems programmed. Look at the up/down pressure limit adjustments and put the new ones in the same position as the old ones.....worked like a charm. A child could make this repair.

Garage door either went up 6” or not at all.
