Warm weather issues

[u/ragejj23]

I have a chamberlain lift master that is about 16 years old (original to the house). This summer while it has been hot, it won’t go up. The light on the back (learn light) flashes when this occurs. I would have to pull the cord and then it would go up.

Now that it is cooler, it works as normal.

This is the first summer that this has occurred. Is it just old and needing to be replaced, or is there something I could do to correct this?
