After Replacing the Circuit Board in My Maxx7500 I Cannot Open the Auto Open Lid with Remote?

Question:

Pretty simple install but everything seems to run backwards. I have a wall remote. If I hit the open button the fan comes on. I cannot auto open the lid, if i do manually then hit the fan button the lid closes. Everything has a one way only plug so not sure whats going on. Do I need to reprogram the remote? Maxx7500

Hello Jeff,

I need to make sure that the Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K is the correct one for your fan. I know you have the Maxx7500, but can you please send me the model number? There should be a sticker on the inside of the fan, please send me the information from that sticker.

I look forward to hearing back form you so we can get this fixed =)
