Thermocouple Connecting Block - Jen-Ken

Oval block is sold separately and does not usually need replacing as often as the probe, clean the connection holes with fine sandpaper rolled up or gently scrape the inside of the holes with a small screwdriver to remove corrosion. Then clean the thermocouple ends with fine sand paper to make sure there is a clean connection. Also scrape the thermocouple wires from the controller to make sure that everything is making good contact.
