Thermocouple Inspection
The small rod protruding into the firing chamber is the temperature sensor, or thermocouple.
CAUTION: Bumping the thermocouple can push it out of the firing chamber. This could cause an overfire! Bumping the thermocouple could also cause inaccu- rate readings.
■A 1/8” diameter thermocouple should extend into the firing chamber ½” - 5 8”.
■A ¼” diameter thermocouple should extend into the fir- ing chamber ¾ - 1” or more.
■Keep shelves, posts and ware 1” - 1 ½” away from the
thermocouple.3
