Hello! It seems like you are experiencing an issue with the 5 peso timer where it frequently times out after only 20 minutes instead of the full 40 minutes that it should be set to. There could be a few possible reasons for this issue:
1. Mechanical Issue: The timer mechanism inside the device may be faulty or worn out, causing it to not run for the full duration. In this case, the timer may need to be repaired or replaced.
2. Programming Issue: There could be a setting or programming error that is causing the timer to stop at 20 minutes instead of 40 minutes. You may need to check the user manual or contact the manufacturer for instructions on how to adjust the settings correctly.
3. Power Supply Problem: If the timer is not getting enough power, it may stop running prematurely. Make sure the timer is plugged into a reliable power source and that there are no issues with the electrical connection.
I recommend checking these possible reasons one by one to determine the exact cause of the issue. If you are unable to troubleshoot and fix the problem on your own, you may need to seek assistance from a professional or contact the manufacturer for further support. I hope this information helps you resolve the issue with your 5 peso timer.
