Error Code C-20

Oven sensor opened

What This Means

Oven sensor resistance over 20 ohms at room temperature; Disconnected or damaged sensor harness; Damaged terminal or wire on harness; Problem with oven sensor connector on main PCB

How to Fix

1. 1

   Disconnect power and open back cover

2. 2

   Disconnect sensor harness from control

3. 3

   Measure sensor resistance - should be around 1000 ohms at room temperature

4. 4

   If resistance is too high, replace oven sensor

5. 5

   Check for damaged terminal or wire on harness

6. 6

   Check resistance of oven sensor connector on main PCB - normal is 0 ohms

7. 7

   Repair damaged harness or replace main PCB if needed
