2. Defective
NTC interface
on PCB?
Measure the resistance
of the NTC sensor and
harness between P18-5
and P18-6 on main circuit
board.
Is the resistance between
4 to 6 kΩ at 20°C (68°F)?
Replace NTC sensor
or harness.
Go to step 2.
NO
YES
YES
Replace the PCB.
1. Defective
NTC sensor or
harness?
Alternative
