Error Code CF1

LF Top Sensor Open/Short — Left Front induction cooktop top sensor is open or shorted

What This Means

CN01T connector disconnected or loose on Left Inverter PCB; Shorted CN01T(Pin2) to CN01Y or CN11F(Pin3); Failed top sensor NTC (normal ~20 kΩ)

How to Fix

1. 1

   OPEN: Check CN01T connection at Left Inverter PCB — if loose, reconnect

2. 2

   OPEN: If connection OK, check if CN01T(Pin2) is shorted to CN01Y or CN11F(Pin3); if shorted, replace PCB

3. 3

   OPEN: If no short, replace the top sensor

4. 4

   SHORT: Measure CN01T resistance — normal is infinite; if shorted, replace PCB

5. 5

   SHORT: If CN01T normal, check resistance of R01T (thermistor on PCB): normal ~20 kΩ; if abnormal, replace PCB

6. 6

   SHORT: If R01T normal, replace the top sensor
