Craftsman 1/2 HP Garage Door opener Remote problem

brisonnyMarch 3, 2007

The remotes for my Craftsman screwdrive 1/2 hp GDO work only at a very short range; about 2-3 inches away from the unit. I have replaced the batteries, but still no success. The problem was intermittent at first (the remotes worked from the car off and on for a while) now they only work when right next to the unit. Thanks in adavance!

Sounds like your logic board is going bad.

Could it be any type of radio interferance, like from my wireless router?

How can I tell my transmitters are working correctly?

Otherwise I guess my best bet is to buy a new opener since a new logic board with shipping is near the price of a new GDO.

Thanks for your reply.

It could be from interference. Look at the small LED just to the left of all those white wires. It is flickering rapidly? That would be a sign of interference and you should start unplugging things until it quits doing that. Random flashing is normal.
