The thermocouple is a small sensor inside the heater that tells the station how hot the air is. If the thermocouple fails or its wires snap, the station "blinds" itself; it stops heating and displays "HE" to prevent a runaway thermal event. 3. Loose or Broken Connections

Identify the four wires leading to the heating core. Usually, two thicker wires are for the and two thinner wires are for the thermocouple . gordak 952 he error portable

Measure the resistance between the two sensor wires. You should see a very low resistance (usually 1Ω to 2Ω ). Step 3: Replacing the Element The thermocouple is a small sensor inside the

If the heating element tests fine, check the continuity of the wires from the handle all the way to the plug. Use your multimeter's continuity beep mode and wiggle the hose. If the beep cuts out, you have a break inside the hose, and the entire handle assembly may need replacement. Pro-Tips for Longevity Loose or Broken Connections Identify the four wires

Running the station at 450°C+ for extended periods will significantly shorten the life of the resistive wire. Use the lowest effective temperature for your solder type.

Occasionally, the issue isn't the handle, but the main station. Vibration or heat cycles can cause the solder joints on the control board (where the air gun attaches) to crack. Step-by-Step Troubleshooting & Repair Step 1: Physical Inspection
