Solution
•
Check coil connector.
•
Measure the resistance of the coil. Measured
value should read 60mΩ, +/- 5%
• Replace damaged induction coil, or faulty
induction PCB.
•
Retest the machine.
•
Check airflow being drawn in under machine. e.g.,
using the machine with feet removed would
impede airflow, or could be a blockage of
underside vents.
•
Retest the machine.
