Yes Check the pin in the connector for good contact if it's OK replace the controller.
No If the thermistor reads 5,000 ohms or less at ambient temperatures it needs to be replaced. If it
reads OL move to step 2. (figure 1G)
You will need to separate the upper and lower deck as described on pages 15-17. Disconnect the
