@OP:
try different brands of LED bulbs and find one that works for you.
With CFL: there's a lot of RFI created within (thus the call for FCC standard imposed on them to keep their RFI emissions low);
RFI is what radio broadcasts, CB, etc. would do over the air: only difference is that RFI is broad-spectrum meaning that it spreads out over a very wide frequency, and it may have an impact on your garage door receiver side (which locates very close to your bulb).
While I haven't have a chance to take apart an AC120V based LED bulb yet, my investigation so far (online) has led me to believe that most of them don't have a lot of RFI-generating components within....but then again: different manufacturers may resort to using different designs...perhaps SMPS based chopper to lower the output voltage then with current regulation before feeding into the LEDs?
SMPS "choppers" are noisy, you know.
