Common Failures
Customers frequently report that the product is not responding, not working, or unable to connect and read the sensor. These issues are often traced back to defective fuse holders, slide switches, and various electrolytic capacitors.
Repair Approach
Repairs typically involve replacing defective aluminum electrolytic capacitors and fuse holders, as well as performing preventative replacements of capacitors. Slide switches that appear open in the circuit are cleaned, tested, and treated with DeoxIT before reinstallation. Additionally, solder joints are inspected, and any compromised connections are re-soldered.
Testing & Quality
Repaired units undergo various levels of testing, including basic power-up tests, burn-in tests without load, and final inspections. These tests confirm proper relay activity and voltage output.
