Service Procedures
IMPORTANT: If performing troubleshooting procedures and an electrical component is found to be
defective, it is important to find out what caused the component(s) to fail. Most electrical failures occur as a
result of other defective components, power fluctuations, or a wire “grounding out”. The only wires in the
entire electrical circuitry of the BE unit that should be grounded are wires #21 and #22 from the Level
Control Board. Any other problems or electrical shorts to ground must be eliminated, or damage to
electrical components will reoccur.
Parts are dependent upon serial number of your unit. Be careful to order and replace the correct part.
Consult the “Parts List and Location Diagrams” for specifics on part numbers and component locations.
Electrical parts are voltage sensitive. Always check that the same voltage components are being replaced.
Installing the improper voltage of a part can be difficult to troubleshoot when problems continue to occur.
Read and follow the “Safety Precautions” section of this manual before proceeding.
TOOLS REQUIRED: Volt/ohm meter (VOM), screwdriver set, crimping pliers, wire cutter/stripper, jumper
wires (a 16 gauge or larger wire with alligator clips on each end), various wrenches (crescent, pipe, hex, allen,
etc.) A temperature probe or thermometer can be helpful.
