Gordak 952 Service Manual: Troubleshooting, Schematic, and Repair Guide

100°C to 500°C (Adjustable via analog potentiometer) Air Pump Type: Diaphragm Pump (Eccentric shaft driven)

Draw this out, and you have a "service manual" for any Gordak 952.

Measure resistance across the thermocouple wires (typically blue and red wires inside the handle). A normal loop is ≈is approximately equal to Ωcap omega

If you cannot revive your unit, remember: the Gordak 952 is so common that most repair shops will fix it for $20. But with this manual, you can do it yourself for $3 in parts. Gordak 952 Service Manual

While we cannot host the file directly here, these are the verified sources to get the and calibration instructions :

The Gordak 952 relies on an analog control circuit. It uses operational amplifiers (usually LM324 or similar) to manage temperature feedback loops. 1. Power Supply Section

Place the tip of the iron or the nozzle of the hot air gun (positioned 5mm away) onto your thermal calibration probe.

Driven by an AC speed controller linked to the front panel potentiometer. But with this manual, you can do it yourself for $3 in parts

: When turned off, the pump continues to run until the temperature drops below 100°C (or 50°C on some models). Do not unplug the machine while the cooling cycle is active to prevent damage to the heating element. Maintenance & Repair

: The station uses a microcomputer-controlled thermostatic system with dual LED displays for precise monitoring. If the temperature is unstable, check the feedback loop and the thermocouple inside the heating element. Component Replacement :

| Pin | Hot Air Handpiece | Soldering Iron Handpiece | |-----|------------------------|--------------------------| | 1 | Heater (AC Live) | Heater (AC Live) | | 2 | Heater (AC Neutral) | Heater (AC Neutral) | | 3 | Thermocouple (+) | Thermistor (Signal) | | 4 | Thermocouple (-) | Thermistor (Ground) | | 5 | Motor (24V DC +) | Not used (or reed switch)|

Warning: Always unplug the unit from AC power before removing the cover to avoid electric shock. A. Replacing the Hot Air Heating Element highly integrated microchip stations.

The Gordak 952 is a classic, widely used dual-function SMD rework station that combines a hot air gun and a soldering iron. It is heavily favored by electronics hobbyists, repair technicians, and engineers for its affordability and standard through-hole component design, making it highly repairable.

The Gordak 952 utilizes an analog closed-loop feedback loop to regulate temperature, which provides high repairability compared to modern, highly integrated microchip stations.

Soak hot air nozzles in isopropyl alcohol to remove carbon buildup.
