Marantec 82424, Power Board for RV 8000 / LC 1000 Series

Marantec 82424, Power Board for RV 8000 / LC 1000 Series

The Marantec 82424 power board is a service replacement board for RV 8000 and LC 1000 Series operators. In these opener systems, the power board is part of the internal electronics that supports the operator power and control functions. It is different from the logic/radio receiver module and different from the light fixture assembly. A technician may consider this board when there are confirmed power-board symptoms such as visible damage, no output to a connected system, relay or power-control failure, or related electrical failure after the rest of the opener has been checked. Since the RV 8000 and LC 1000 systems are not the same as later Synergy or M-Line operators, the 82424 number and board layout should be confirmed before ordering.

Professional Advisory

Disconnect power before servicing a garage door opener. If the opener has damaged wiring, signs of heat, repeated fuse failure, unsafe door movement, or a door that will not balance by hand, have the system checked by a qualified garage door technician before replacing parts.

Product Questions and Answers

Which openers use the 82424 power board?

It is listed for Marantec RV 8000 and LC 1000 Series operator applications.

Is 82424 the same as the 88573 power board?

No. 88573 is a different M-Line EOS power board kit. The 82424 is for RV 8000 / LC 1000 references.

Can a bad power board cause a dead opener?

Yes, but incoming power, fuses, wiring, harnesses, and other internal parts should be checked before replacing the board.

Is this a radio receiver?

No. It is a power board. The RV 8000 receiver is a separate module.

Should a homeowner replace this board?

Because power-board service can involve hazardous voltage, it is best handled by a qualified garage door technician if there is any uncertainty.
