Check if the heater is broken. 2. Check if the connector of the heater is disconnected. 3. Check if the harnesses are connected properly to the terminals of the heater lamp. 4. Check if the thermostat is blown. 5 Check the MAIN board 1. Check if the connectors are disconnected. 2. Check if the conductor pattern on the MAIN board is short circuited or open circuited. 3. Replace the MAIN board. 6 Clear the status counter After repairing the matter which caused the error [C413 / C414], perform the following: 1. Turn ON the power while [0] and [8] are pressed simultaneously. 2. Key in “2002”, then press [START]. 3. Change the current status counter value “1” or “2” to “0”, then press [OK] (to cancel [C413 / C414]). 4. Turn the power OFF and then back ON. Make sure that the equipment enters the normal ready state.
