Garage Door Opener Not Working If Lightbulb is Still On
This is a weird one I know.
I have an older, Sears garage door opener (installed in 1991, model 139.53600) that does not have safety sensors.
For the last few years the remotes will not operate the GDO if it is cold outside ÂANDÂ the 40w light bulb on the opener is still on.
In other words, if it is warm outside (70Âs & above) the remotes work fine, but if itÂs cold I have to wait till the light on the opener turns off before the remotes will work.
There are no safety sensors on this system, and it works fine from the wall switch, I also replaced the battery and have tried this with multiple remotes which work fine ÂifÂ the GDO light bulb is off. It seems like the opener doesnÂt sense the remote if it is cold ÂandÂ the GDOs light is on. I tried unplugging and replugging the unit but same weirdness is happening.
I know it has to be some little $2 part and hate to buy an entire new unit just for that. Any suggestions or ideas out there?
