If the cable and connectors are perfect, the Triac (BT136 or similar) on the mainboard may be shorted or open.
Unscrew the multi-pin connector connecting the handpiece to the metal front panel.
When your Gordak 952 displays "H-E", it stands explicitly for . The onboard micro-control unit (MCU) continually samples resistance and temperature data from the handpiece. If the readings break past factory thresholds, the safety relay triggers the shutdown mechanism. Primary Triggers of the Error How to: Fix a Soldering Iron With The Error S-E or 5-E
: Open the handle to see if the heating element has slipped out of its socket or if a wire has desoldered. How to Replace the Heating Element gordak 952 he error portable
Before assuming the worst, follow this systematic guide to diagnose and potentially resolve the HE error. Always unplug the station from the mains power before opening or checking any internal components.
If you’ve replaced the heater and checked connections but still see :
The Gordak 952 monitors the hot air gun's temperature via a thermocouple located within the heating element. The "HE" error generally indicates a break in this feedback loop or a complete failure of the heating component. Potential causes include: If the cable and connectors are perfect, the
Inspect the female socket pins on the station for debris, corrosion, or bent contacts.
Remember: The key is systematic testing—starting from the handle connector, moving to the heating element, then the thermocouple, and finally the main board. Don't let the HE Error stop your electronics projects. Repair it, reinforce it, and get back to soldering.
: Carefully unscrew the plastic casing of the heat gun or soldering iron handle. Look for broken wires or visible black charring on the heating element. How to Replace the Heating Element Before assuming
Safety first
Check the wires inside the handle, specifically at the bend point, to see if a blue wire has snapped. Re-solder any disconnected wires. 3. Replace the Heating Element
