ok i kind of know whats wrong i need someone to come to my house and fix. i took this apart to clean and try to get to the vent motor i took the control panel apart. took the computer chip board off of the back of the c. panel flipped it over and found some burnt circiuts on the chip board which would explain why the over range lights didnt work anymore. i wiped the front of the control panel with a damp cloth because my unit was just one big greasy mess. hooked everything back up and now the control panel isnt working right and after about 2 minutes either codes f4 or f3 come up i think the chip board is bad but would like in house service to check the unit if possible
