5-29
Symptom : Not heating (F-11, F-13, F-14, F-15, F-19)
Not heating (Cool : on display)
• Check inverter PCB _ IC parts
Check temperature on display,
after 3 minutes check it again.
(ex. before 90↑→ after 90↑)
※ Method : Temperature checking
For 2 seconds, press ‘Cancel key’ and ‘Start key’ (double-key)
For damaged IC test, Check the resistance value of IC Pin and ground using tester.
If all tests are OK, see again ‘Error Code Case’ page.
Normal levels of resistance value ±10%↓ difference : Normal(OK)
Short or ±10%↑difference : Abnormal(NG)
※ Normal Level Resistance
1. 5V DC : 4.2Kohm (2 pin)
2. 15V DC : 4.8Mohm (4 pin)
3. Temp. AD : 15~20Kohm (6 pin)
※ It may differ slightly depending
on the tester.
