Need a service manual for a Kenmore Vent Hood Microwave made by LG

Mod# 721.63762300
Ser# 302KM00186

Need a manual that tells how to check if the controller is sending the correct signal to the inverter board.

F9 error says to check all connections on inverter if getting below .5 amps input current then to replace the inverter board and if it still doesn't work then to replace the controller.

I don't want to be stuck with a $100 inverter board and then find out that isn't the problem and have to order and replace the control board.

Uses inverter board 6871W1S019A

An LG model that uses the same inverter board is: LMVM1945T

So a service manual for the LG model if none can be found for the exact Kenmore should work.
