10.3 Measure the Resistance before Replacing
NOTE:
Measure the resistance when the heating element is at room temperature.
1. Resistance value of heating element is ＜4Ω.
2.
If the resistance value is not normal, replace the heating element. Refer to the
instructions included with the replacement part.
10.4 Measure the Resistance after Replacing
After replacing the heating element:
