There could be several reasons why your timer is not functioning properly. It could be due to a faulty connection, a damaged relay, or a programming issue.
You can use a multimeter to test the continuity of the relay. If there is no continuity, then the relay is most likely damaged and needs to be replaced.
First, check if the power source is connected and working. If it is, then check the programming of the timer to make sure it is set to turn on at the correct time. If the programming is correct, then there may be an issue with the internal components of the timer and it may need to be replaced.
This could be due to a programming issue or a faulty relay. Check the programming to make sure the timer is set to turn off at the correct time. If the programming is correct, then test the relay for continuity. If there is no continuity, then the relay may need to be replaced.
To prevent your timer's relay from malfunctioning, make sure to regularly clean and maintain the timer. Check for any loose connections and replace any damaged parts as soon as possible. Also, avoid overloading the relay with too much power as this can cause it to fail.
