: Sometimes an intermittent connection in the sensor circuit can trigger heater-related errors.
If the thermocouple fails (shorts or opens), the microcontroller thinks the temperature is stuck at 20°C (room temp). It sends full power to the heater. When the temperature doesn't reach 50°C within the timeout window, it assumes the heater is dead and triggers H-E.
: Test for continuity with a multimeter. If there is no continuity, you must replace the Replacement Heating Element .
The error on a Gordak 952 indicates a Heater Error , meaning the station has detected a failure in the heating circuit or the heating element itself . Common Causes & Solutions
A: Not necessarily. The fan runs on DC low voltage (24V or 12V). The heater runs on AC mains. The fan working means your transformer and bridge rectifier are fine, but the AC circuit (triac, heater, wiring) is suspect.
The Gordak 952 uses a 5-pin or 7-pin aviation connector where the handpiece plugs in. The female pins inside this connector can loosen over time, losing contact with the handpiece pins.
