Replacing the Fuse and Fuse Holder

If the unit (non-CE) is completely inoperative, but power exists at the wall receptacle, check the 15 amp fuse(s) and fuse holder(s) as follows:

To avoid electrical shock or property damage, disconnect power before installing or servicing equipment. A qualified technician must perform the service procedures.

Replacing the Fuse

1. Unscrew the fuse holder cap by turning it counterclockwise. (Located under the power cord.)

2. Pull the fuse from the cap and check for continuity by placing the leads of a multimeter or continuity light on opposite ends of the fuse.

   The fuse should show closed or read no resistance.

3. If fuse is defective, replace it with a new one. Be sure replacement fuse is identical to the one being replaced. (208 or 240 volt units have 2 fuses and both should be checked.)

Replacing the Fuse Holder

If fuses show good, the fuse holders may be bad. Check the fuse holders as follows:

1. Remove the screws securing the rear access panel and pull panel down.

   

2. Remove the wires from the fuse holder, and check for continuity by placing the leads of a multimeter or continuity light on terminals of the fuse holder. The fuse holder should show closed or read no resistance.

   

3. If fuse holder shows it’s defective, remove the screws securing it to the panel and replace it with a new one.

4. Reinstall the rear panel and make sure the fuse holder has a 15 amp fuse in it.

5. Restore power to the cabinet and it’s now ready for use.
