SPECIFICATION OF ERROR
When a basic performance and the function are ruined
When the dangers of the state of the high temperature and the ignition, etc. are
foreseen
When you mistake the setting of the heating time
When neither the power supply nor the environmental condition are proper
When informing of the exchange time of parts
