5-33
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
U1 : MICOM (R51076C, Renesas) : 15~20Kohm (2 Pin)
U1 : MICOM (R51076C, Renesas) : 4.5Kohm (10 Pin)↑
U6 : Gate driver IC (2EDL05I06PF, Infineon) : 1.0Mohm↑
U7 : OP-AMP (SN358, AUK) : 4.5Kohm↑
U8 : Dual comparator (KIA393F, KEC) : 1.0Mohm↑
※ It may differ slightly depending on the tester.
