Troubleshooting
Checking the resistance values
Part of troubleshooting some of the system error codes related to the Dryer and Curing Assemblies involves
checking the resistance values. In the tables shown below are the resistance values that would typically
be seen when the resistors have not been used for 1 hour.
Type of resistor Dryer resistance value (ohms) Upper spec Lower Spec
60”
Steady 27.0
