Questions & Answers

For Samsung Vent Hood Control Board (Part Number: OEM21043602)

1 Answer

Hello Rob. KEYPAD, KEYBOARD REPLACEMENT RV SERIES RAISED VENT Removal of the cooktop is not required. ? Raise the vent sleeve by pressing the UP/DOWN button. If the unit is dead, raise the vent by removing the black motor sleeve wires L3 and N3 from the main PCB and hook direct to a power source (Auxiliary power cord, pigtail etc) ? With the vent in up position turn off the electrical power to the vent and remove the vent electric cover plate. ? If a cabinet blower is used, disconnect the blower from the vent by loosening the three wing nuts located above the blower and lifting up on the blower retaining bracket. ? If a remote blower is used remove the cover plate. ? Disconnect the 14 wire Molex plug from the main PCB. ? Remove the screws, 1 on each side of the sleeve. Lift top cap assembly from the sleeve assembly. Guide the Molex plug through the electric box and through the channel in the sleeve assembly. ? Remove the right end cap (pressed in). Slide out the bezel, keypad and keyboard as one unit. Replace desired part and reinstall in reverse order.

Bob J for Model Number rv36w - Dacor downdraft for cooktop

Our keyboard does not light up or raise the down draft unit any longer (or turn on the blower). I already ordered the part 82633 from you guys (and the keyboard still does not light up or operate the down draft) so I am wondering if it is more likely that the main control board needs replacing? Or, is there any way to test the main control board? I tested the new keyboard circuit board and it seems to have power to it according the volt meter. Thanks!! Bob J.

Bob, With the unit not moving up and down and the blower not coming on, this would most likely be caused by the main control board. Unfortunately we do not have any wiring information to help with the testing procedures for this unit.

Hi. The main control board part DE81-07744A is a upgraded part and does not look the same due to different part upgrades. The keypad ribbon connector plugs into the board in a white outlined pin connection. It is notched one way for correct insertion. You can see it in our part view behind the "Blue Fan wire lead" Kind of hidden. Thank You.
