6.3.2 Verifying Oven Temperatures<br />
Technicians can determine if self cleaning ovens reach the proper cleaning<br />
temperature using pellets with pre-calibrated melting points at 450 °C (850<br />
°F). The pellets are placed on a flat piece of aluminum foil situated on the<br />
oven's center rack (see Fig. 65). The cleaning cycle is activated and as the<br />
temperature reaches 450 °C (850 °F), the pellets begin to melt. When the<br />
cleaning cycle is completed and the oven has cooled, the pellets are<br />
inspected—complete melting of the tablet verifies that the nominal cleaning<br />
temperature has been achieved.<br />
