SERVICE MODE LED COMBINATIONS
Service mode can be started with a cold or warm appliances. The only exception is when testing the digital input
heater switch that requires a cold appliance.
When service mode starts, all light indications are on and all components are off. Service mode activates multiple
components simultaneously. Sensors are self-diagnosing while components must be checked manually.
Turning a component on provides electricity to the component. This makes it possible to test that the power supply is
getting through and if there is voltage absorption.
For example, if activating the refrigerator compressor does not work, use a tester to see whether the motor or the
power board causes the problem.
