TROUBLESHOOTING

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.

•Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.

•All electronic components have ac voltage and dc voltage potential on their terminals. Shorting of ter- minals or the application of external voltages may result in board failure.

•Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent.

If an intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.

•Make certain that all electrical connections are tight and isolated.

WARNING

•Exercise extreme caution when servicing electrical equipment.

•Turn power OFF when servicing, except when electrical tests are specified.

•Follow recommended service procedures.

•Replace all protective shields or safety notices.
