FAILURE CODES
“F” (Failure) DISPLAY CODES
Before doing any action, perform the following step1~3.
Step1.
Unplug range or disconnect power.
Step2.
Check if connector is fully seated or not.
Note:
All units in the first few days of use should be
checked for mis-wiring or loose connections.
WARNING
• Disconnect power supply cord from the outlet
before servicing
• Replace all panels and parts before operating.
• Reconnect all grounding devices
Failure to do so can result in death or electrical
shock
!

CAUSE
CORRECTIVE ACTION
A. Perform step 1 through 2 above
B. Replace keypad or keypad assembly
(if F code recur, go to C after unplugging
or disconnecting)
C. Replace Control (PCB) assembly
A. Perform step 1 through 2 above
B. Check wire and connections from control to latch
C. If motor operate, check integrity of latch mechanism
- check the micro-switch (refer to
component test section)
- check integrity of door locking mechanism
D. If motor didn’t operate, check continuity of
the latch motor and electrical connections
- if the wiring is bad, replace the harness
- if the wiring is good, replace the door
motor assembly
- if F code recur, replace control
A. Perform step 1 through 2 above
B. Open the back panel and check continuity of
the sensor and Control (PCB)
C. Disconnect sensor from harness
D. - Measure
Ω
value between connector pins :
Approximately 1090
Ω
(at room temperature:
77F/25°C)
- Measure value between sensor chassis
and any connector pins
:
Ω
value should read OPEN
=> if there is any problem, Replace oven sensor
E. If you couldn’t find any problem, Replace
Control (PCB)
A. Perform step 1 through 2 above
B. Open the back panel and check continuity
of the sensor and Control (PCB)
C. Disconnect sensor from harness
D.- Measure
Ω
value between connector pins
:Approximately 50k
Ω
(at room temperature
77F/25°C)
- Measure value between sensor chassis
and any connector pins
:
Ω
value should read OPEN
=> if there is any problem, Replace
warming drawer sensor
E. If you couldn’t find any problem, Replace
