M330 Manual Service  28

To check which heating element is broken:

1. Disconnect the AC power.

2. Locate which heating element is broken. Disconnect only one of the wires attached

to an end strap.

3. Use Ohmmeter to measure across each heating element. If any of the above

readings are OPEN circuit or greater than 100 ohms, then the element is bad and

needs replacement.

Note: Sometimes the element may show OK when it is cold, but opens when it gets

hot. If all measurements are ok, problem is due to some other component in the

heating circuit. Do not proceed with this instruction.
