Common Causes for Induction Unit Failure
One or more of the following conditions may affect the
function or contribute to the failure of an induction unit:
• Using unsuitable cookware such as non-induction pans,
oversized pans, or damaged pans.
• High ambient temperature.
• Inadequate ventilation causing hot air to re-enter
through the air intake slots.
• Dirty air intake filter.
• Empty pan is left on the hob when the unit is ON.
Symptoms
• When a malfunction occurs, the induction unit may be
in one of the following states:
• The induction unit stops working immediately.
• The induction unit continues to work in a power
reduction mode.
• The induction unit continues to work as usual.
• For any unit equipped with an indicator lamp or a digital
display, see section Troubleshooting Chart With Error
Code / Indicator Lamp Flash Code
• For any unit without an indicator lamp or a digital
display, see section Troubleshooting Chart Without Error
Code / Indicator Lamp Flash Code
• NOTE:
The cooling fan starts when the ambient temperature
in the control area exceeds 130ºF/55ºC.
At heat sink temperature higher than 160ºF/70ºC, the
controller automatically reduces power to keep the unit
in normal operating conditions. The cooker runs in a
non-continuous mode. This mode can be heard.
Boil Test: Performance of Cookware
(Test for 3.5kW or 5.0kW Coil)
Perform a boil test to verify the performance of a pan for
induction cooking.
• Add one liter of cold water into the pan (optimal when
use pan with bottom diameter of 24cm) and bring it to
boil. Compare the total boil time to the guideline below:
• 3.5kW Coil, approx. 140 seconds
• 5.0kW Coil, approx. 85 seconds
If time to boil exceeds the above guideline, then the pan is
not suitable for achieving optimal efficiency. Please contact
your supplier to purchase suitable induction pans.
If the induction unit does not function as expected despite
using quality induction pans, refer to the troubleshooting
charts.
