NOTE: The refrigerator and freezer thermistors

are identical and are removed in the same

manner.

2. Depending on the thermistor, open the

freezer or refrigerator door, and remove

any items from the shelf that are in front of

the thermistor. It may be necessary to

remove the shelf as well. The thermistor
