Because the hot air gun is moved frequently, the wires inside the flexible hose are subject to constant stress. A single frayed wire—either for the heater or the sensor—can trigger the error. 4. Cold Solder Joints on the PCB
If the element is faulty, you can purchase a "Gordak 952 Heating Core" online quite cheaply. the old wires, noting their positions. Slide out the old ceramic core. 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 Because the hot air gun is moved frequently,
The Gordak 952 "HE" error is rarely a "death sentence" for your machine. In 90% of cases, it is a simple matter of replacing a or resoldering a loose wire in the handle. By understanding the sensor feedback loop, you can get your rework station back in action and keep your repair projects on track. Cold Solder Joints on the PCB If the
On Gordak units, "HE" stands for . It indicates that the control board has detected a problem with the heating circuit of the hot air gun. Specifically, the system is not receiving the expected feedback from the thermocouple (temperature sensor) or the heating element itself is failing to draw current. Common Causes of the "HE" Error 1. Burnt Out Heating Element
Set your multimeter to Ohms (Ω). Measure the resistance between the heater wires. You should typically see a reading between 70Ω and 100Ω (depending on your local voltage). If it reads "OL" or infinite, the element is blown.
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
