The circuit board in my B2000 has failed and I need to replace it. What do I need to order?

All of the older circuitry is obsolete and no longer available, so if the unit is older it may need to have the circuitry upgraded.

The easiest way to determine this is to look at which pendant control the unit has; the box with the toggle or 3 red buttons.

If it is the box with a toggle, then the entire circuit and pendant assembly must be replaced with a HC12 kit, which include the new circuit board, pendant assembly, power cord, and handle. The old pendant and circuitry will not work with the new circuitry due to the old circuits were relay controlled and the new circuits are digital.

If you need a HC12, check the wire harness for your limit switches that plugs into the board. Is the wire harness a long rectangular harness with 1 row of 8 pins(extremely old style), or is it square with 3 rows of 3(current style since early 1990’s)?

If you have the old rectangular harness a jumper, you will also need a DA7070900 jumper assembly to splice into the old wiring and allow the wiring to fit the new board.
