Error Code F-1

Oven sensor open circuit

What This Means

Oven temperature sensor wire broken or disconnected; Loose connector at oven sensor or at Power PCB CN31; Failed oven temperature sensor (open)

How to Fix

1. 1

   Press CLEAR/OFF key to cancel the current cook operation

2. 2

   Allow oven to cool for at least one hour

3. 3

   Disconnect power to the range

4. 4

   Check the oven sensor connector for looseness; reconnect if loose

5. 5

   Disconnect the oven sensor from the harness and measure resistance: normal is approximately 1.06 kOhm at 65F to 1.12 kOhm at 85F (1.09 kOhm +/- 10% at 77F/25C); replace sensor if out of range

6. 6

   Check Power PCB connector CN31 for looseness or terminal damage; reconnect or replace harness if defective

7. 7

   Restore power and enter test mode to verify sensor value: press CLEAR, then press BAKE+BROIL simultaneously for 1 second (failure code display), press BAKE+BROIL again (S/W version display), then press COOK TIME to view sensor value — normal reading is 65F to 95F at room temperature

8. 8

   If sensor value is abnormal, replace Power PCB

9. 9

   If sensor value is normal, fault is resolved
