Check the rear fuse capsule. Measure AC voltage across the main power switch output terminals. Test the transformer primary winding resistance; an open loop indicates thermal fuse failure inside the transformer.

100°C to 500°C (Adjustable via analog potentiometer) Air Pump Type: Diaphragm Pump (Eccentric shaft driven) Gordak 952 Service Manual
Users sometimes report that the hot air gun does not get hot enough to melt lead-free solder, even at maximum temperature.
Open the hot air handle. Check for broken thermocouple wires. Broken iron element or faulty 5-pin aviation plug. Check the rear fuse capsule
Let’s simulate a scenario. Your Gordak 952 display is on, but the hot air wand blows only cold air. Here is how you use the service manual’s logic to fix it.
If the airflow drops significantly or noise increases, the pump requires attention. This comprehensive service guide serves as your unofficial
The Gordak 952 features an automatic cooling cycle. When turned off, the pump runs until the nozzle temperature drops below 100°C. If it never stops, the logic board is falsely reading a high temperature due to a broken thermocouple wire or a failed LM324 op-amp.
Never leave the heating elements unattended during testing.
