    Liftmaster 1/3 HP working intermittently in rainy weather or high temps. Typically it works fine with no issues. Will make a click and light comes on with opener push but door doesn't open. Then release latch and manually open door and opener will work and trolley will move back and forth until it clicks in then door will close and open with opener.

    I have video of it all but it won't let me upload. 

    Anyway, can this be weather related. I have had this happen when we have had extremely high temps and now we are having extreme humidity due to a lot of rain. 

    Only other thing I think it could be is a start capacitor possibly or have read about small breaks in solder and temps affect it.somehow. everything is greased and rolls properly.  Weather affecting Liftmaster 1/3 HP Opener? 20240110

    Your Liftmaster 1/3 HP opener experiencing issues in specific weather conditions could indeed be weather-related, and your suspicions are on the right track. Here's how the weather might be affecting it and possible solutions:
    Weather Impacts:

    • Moisture in the air can affect electrical components, causing corrosion or temporary malfunctions.


    • Heat can stress internal components, potentially affecting their performance.


    Possible culprits:


    • Start capacitor: As you mentioned, a failing capacitor can cause intermittent startup issues. Heat and humidity can exacerbate its weakness.


    • Circuit board: Delicate electronics on the board are susceptible to moisture and temperature fluctuations.


    • Safety sensors: Weather variations might temporarily confuse the sensors, preventing complete operation.


    • Loose connections: Humidity can loosen electrical connections, causing intermittent functionality.

    Thank you for the reply. It does show 5 blinks indicating a RPM sensor. But it has been working again. Driving me crazy, not much rhyme or reason to it except the weather.
