o
C temperature
from the panel then displays an
“OFF” on the panel after a few minutes.
SOLUTION:
The thermal sensor may be broken and needs to be replaced.
PROBLEM 3: HOT-AIR GUN ACTUAL AIR TEMPERATURE IS NOT INCREASING
Description: Actual temperature reading is not increasing based on desired level.
SOLUTION:
The heating element may be broken or is at the end of its life and needs to be replaced.
PROBLEM 4: THE UNIT IS VIBRATING TOO MUCH
SOLUTION: Check if the pump is properly secured. Unplug the system from the main power

The Aoyue int 852A+ pro/ int 852A++ pro SMD Rework is a
reworking tool designed to remove and/or repair surface mounted
devices such as SOIC, CHIP, QFP, BLCC, BGA, and so on.
It has several safety features such as the auto-cooling process of
the Hot Air Gun. This functionality protects the device (and its
components) from excessive heat upon reaching any of the following
conditions: (1) when the soldering gun remained idle on its resting
handle after a certain period and (2) when the temperature of the
device is above a safe threshold upon turning off.
