I recently encountered an issue with my leak sensors where they were triggering false alarms. After some investigation, I discovered that the problem was due to flux contamination on the circuit boards. Here’s how I resolved it:
-
Tools Needed:
- Small Phillips screwdriver
- Pin for removing rubber plugs
- Q-tips
- Electrical cleaner
- Paperclip
-
Steps to Clean:
- Remove the battery and peel off the adhesive pad.
- Use a pin to remove the rubber plugs and screws.
- Carefully lift out the circuit board using a paperclip.
- Clean the contamination with an electrical cleaner, focusing on the body and remote sensor areas.
- Reassemble the sensor.
-
Results: While this fixed one sensor, others still had issues and were returned. I hope this guide helps others facing similar problems!
This experience taught me the importance of checking for hidden issues like contamination. If you’re dealing with similar sensor problems, I recommend inspecting the circuit boards as a first step. Happy troubleshooting!
