Troubleshooting the Gordak 952 "HE" Error: Causes and Solutions
The Gordak 952 is a workhorse in many electronics repair shops, valued for its dual-functionality as both a hot air rework station and a soldering iron. However, few things are as frustrating as being in the middle of a delicate SMD repair only to have the digital display flash a cryptic "HE" error code.
If your Gordak 952 is showing "HE," it typically signals a Heating Error. This is a safety mechanism designed to prevent the machine from overheating or operating under unsafe conditions. Here is a comprehensive guide to understanding, diagnosing, and fixing the "HE" error on your portable rework station. What Does the "HE" Error Mean?
On Gordak units, "HE" stands for Heating Element error. 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
This is the most common culprit. Inside the handle of the hot air gun is a ceramic core wrapped in resistive wire. Over time, these wires can fatigue, crack, or burn out completely, breaking the electrical circuit. 2. Faulty Thermocouple
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
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
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
Before opening the unit, check the plug connection where the hot air gun attaches to the main station. Ensure the aviation-style plug is seated deeply and the screw ring is tightened. A loose plug is a frequent cause of intermittent "HE" errors. Step 2: Testing the Heating Element
To confirm if the element is dead, you will need a multimeter: Unplug the station from the wall. Disassemble the hot air gun handle (usually 3–4 screws).
Identify the four wires leading to the heating core. Usually, two thicker wires are for the heater and two thinner wires are for the thermocouple. gordak 952 he error portable
Heater Test: 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.
Thermocouple Test: Measure the resistance between the two sensor wires. You should see a very low resistance (usually 1Ω to 2Ω). Step 3: Replacing the Element
If the element is faulty, you can purchase a "Gordak 952 Heating Core" online quite cheaply. Desolder the old wires, noting their positions. Slide out the old ceramic core.
Insert the new core and resolder the wires. Ensure you use heat-shrink tubing to prevent shorts. Step 4: Inspecting the Hose Wires
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
To prevent the "HE" error from returning, follow these maintenance tips:
The Cooling Cycle: Never turn the station off directly using the main power switch while it’s hot. Always turn off the heat dial/button first and let the station run its auto-cooling process until the air turns cold. This prevents the ceramic core from heat-soaking and cracking.
Avoid Max Temps: 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.
Stable Voltage: If your local power grid flickers, use a surge protector or voltage stabilizer. Conclusion
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 $10 heating element 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. Troubleshooting the Gordak 952 "HE" Error: Causes and

The "H-E" error on a Gordak 952 soldering and rework station indicates a Heater Error. This occurs when the unit detects a failure in the heating circuit or the heating element itself is physically damaged. Common Causes & Troubleshooting
Heating Element Failure: The most frequent cause is a burnt-out or broken heating element in the hot air wand or soldering handle.
Loose Connections: Intermittent "H-E" messages can be caused by loose wiring or pins inside the handle connector.
Sensor Issues: In some cases, oxide build-up on the internal connections can trick the controller into sensing a heater failure.
Circuit Board Faults: Less commonly, a failed triac or a malfunctioning microcontroller (MCU) on the internal control board can trigger this error. Repair Steps
Check Connections: Unplug the unit, then disconnect and reconnect the handle to ensure it is properly seated in the base unit.
Inspect the Element: Open the handle/wand and look for visible cracks in the ceramic or broken wires.
Measure Resistance: Use a multimeter to check the resistance of the heating element wires. A reading of "infinity" or "open circuit" confirms the element is dead.
Replace the Element: Replacement heating elements are widely available and relatively inexpensive. You will need to desolder the old wires and solder the new ones in the correct order. Q: Is the Gordak 952 HE Error dangerous
Warning: Always disconnect the power before opening the station or handle to avoid electric shock.

. This typically indicates a failure in the heating element circuit, such as an open circuit or physical damage to the element itself. American Hakko Understanding the H-E Error Definition
: It signifies a "Heating element abruption" or other related electrical breakdown within the heater circuit. H-E (Flashing)
: If the error code is flashing, it specifically means the heating element temperature is out of control, likely due to a control board breakdown. Common Causes Burned-out Heating Element
: The most frequent cause is a failed ceramic heating element in the hot air wand or soldering handle. Loose Connections
: Poor contact or disconnected wires within the handle or at the aviation connector. Control Board Issues
: Faulty triacs or other components on the main PCB failing to regulate power to the heater. Troubleshooting and Repair Steps How to: Fix a Soldering Iron With The Error S-E or 5-E
Q: Is the Gordak 952 HE Error dangerous?
A: The error itself is a safety feature. It prevents the unit from overheating or running without temperature feedback. However, continuing to operate a faulty unit could lead to electrical shock or fire if insulation is damaged.
1. Handle Cable Fatigue
This is the most common cause of errors in portable rework stations. The handle is connected to the main unit by a thick, multi-core cable. Because the handle is moved constantly during rework, the internal wires can fatigue and break over time.
- The Fix: Inspect the cable near the handle base and the connector plug. Wiggle the cable while the unit is on; if the error flickers or the temperature reading jumps, you have a broken wire inside the sheath.
1. Most Common Causes (Portable Units)
Portable/handheld Gordak 952 units are more prone to these issues due to cable flex and compact design.
| Cause | Likelihood | |-------|-------------| | Broken heater wire inside the handle | High (from twisting/flexing) | | Loose connection at the main PCB plug | Medium | | Failed thermocouple (temperature sensor) | Medium | | Triac / SSR failure on the main board | Low |
