Error Code F6

Oven hot — oven temperature exceeds 650F continuously for 2 minutes during cooking (excludes self-clean)

What This Means

Heater relay stuck closed (shorted relay contacts); Shorted oven sensor giving false low temperature reading; DLB relay shorted

How to Fix

1. 1

   Unplug the unit

2. 2

   Check resistance of thermistor at CN31 pins 4 and 5 of Main PCB — normal approximately 1.09 kOhm at 25C; if abnormal, replace the defective thermistor

3. 3

   Check resistance of broil igniter relay: measure Tab 02 and Tab 22 — relay designation RY12; normal is infinite (open); if shorted, replace Relay PCB

4. 4

   Check resistance of convection igniter relay: measure Tab 02 and Tab 21 — relay designation RY11; normal is infinite; if shorted, replace Relay PCB

5. 5

   Check resistance of DLB relay: measure Tab 23 (or Tab 24) and Tab 25 — relay designation RY13; normal is infinite; if shorted, replace Relay PCB

6. 6

   Plug in the unit and enter test mode (select 't3') to verify thermistor value — normal is 70F to 90F at room temperature

7. 7

   If thermistor value is abnormal after Relay PCB is normal, replace the Main PCB
