TROUBLESHOOTING

WARNING

 Do not remove the cover of the inverter when the power

is ON to avoid injury caused by electrical shock.

This control does not require maintenance under normal conditions. If you

encounter a problem, read all instructions provided with this control and double-

check the wiring. If problems persist, contact your source of purchase or a

Bodine Authorized Service Center and describe the problem in detail.

Performing unauthorized repairs will void the Warranty.

GENERAL EVALUATION – Knowing the circumstances under which the problem

occurred can help to identify the root cause of the problem.

Has the system ever operated properly?

If the control was just installed and

doesn’t work right, then it is likely that something wasn’t done correctly in the

installation. However, if the system has been working for an extended period of

time and just recently stopped working, then this would indicate that the control

was initially installed properly but something has somehow changed.

Is the problem continuous or intermittent? If the problem always occurs and

never goes away, then it would indicate something inherently wrong in the

connections or a defective component. On the other hand, if the system

operates properly most of the time and only occasionally does something wrong,

then this might indicate loose connections or electrical noise interference.
