CHECK AND TEST 1
Remove the mainboard cover.
Check if terminal is loose, full of foam.
If loose, reinsert the terminal.
If terminal is full of foam, use tweezers to remove foam.
Test resistance of sensor from terminal in PCB area.
Follow below table to find out sensor position and measure temperature of sensor position.
Unscrew potentiometer cover.
Remove cover from cavity.
Disconnect terminal for potentiometer.
Disconnect terminal of LED.
Take the potentiometer away.
CHECK AND TEST 2
Check if terminal of potentiometer is loose or
full of foam after removing plastic cover from cavity.
If loose, reinsert the terminal. If terminal is full of foam, use tweezers to remove.
After reinserting the terminal or removing foam
from terminal, please retest resistance of sensor from terminal in PCB area.
CHECK AND TEST 3
Connect 2 pins in red circles, then test the 2 pins indicated by red arrows on potentiometer.
CHECK AND TEST 4
Check wire connection in foam from terminal in
PCB area to terminal on potentiometer.
CHECK AND TEST 5
Step 1
Test resistance of sensor from terminal on potentiometer.
Follow below table to find out sensor position and measure temperature of sensor position.
