Error Code F-6

Oven is too hot — bad oven sensor or bad control (PCB); relay welded closed

Moderate

Address soon - your appliance may not work properly

What This Means

Oven temperature sensor shorted (reads too low, causing PCB to keep heating); Bake relay (RY57) welded closed on Power PCB; Broil relay (RY58) welded closed on Power PCB; Failed main PCB

How to Fix

  1. 1

    Press CLEAR/OFF; allow oven to cool completely

  2. 2

    Disconnect power and the main oven sensor connector

  3. 3

    Measure oven sensor resistance: normal approximately 1.06 kOhm at 65F to 1.12 kOhm at 85F; if abnormal, replace main oven sensor

  4. 4

    If sensor is normal, remove the Power relay PCB harness

  5. 5

    Check bake relay (RY57) for weld damage by measuring resistance: welded = continuity, normal = infinite (open); if welded, replace Power PCB

  6. 6

    Check broil relay (RY58) for weld damage in the same manner; if welded, replace Power PCB

  7. 7

    If both relays test normal, replace main PCB

  8. 8

    If replacing Power PCB resolves the relay weld issue but main PCB is still suspect, replace main PCB
