My springs were replaced about 9 months ago with the same size that was already there - 207x28
I needed an unrelated repair but the first thing this guy said was that the springs were not the right size, as it was too difficult to manually open the garage door. He recommended 218. He said if I continue to use these springs my motor will likely blow.
The original company says what the installed is fine but they will replace if I want them to.
I don't know what to do...
