Sometimes Linear LDO50 garage door is dead and won't open or close with remote control or wall switch. Once we leave it alone for 2-3 hours or sometime overnight, it starts working. This goes on 20% of the times. Looks like it takes a break to cool down something. Very frustrating. What is wrong and how to replace unreliable part? Any YouTube Video?
