Yes
Is the value of thermistor
normal?(Refer below)
Check with the test mode
To enter the test mode, follow these steps:
1. press the “CLEAR” button
2. press the “BAKE”, “BROIL” button
at the same time
3. press the “BAKE”, “BROIL” button at
the same time again.
Software version is displayed at the left

No
Range Of the resistance
Plug the unit
Is the resistance of
thermistor normal?
Check:
Pins 1and 2 of CN13 wiring in main PCB
Normal- approximately 1.09kΩ at 25˚C
No
Replace the
failed
thermistor
5
Yes
Unplugged the unit

6
Replace the Relay PCB
If it doesn’t work even though changing the
Relay PCB, you should replace the Main PCB.
