What to do if my Broan B110H65RT displays error W32?

If your Broan Fan is showing a W32 error, start by visually inspecting the exhaust damper system. Clean the filters, distribution registers, and the outside supply hood. Ensure the ducting isn't squeezed or bent. If that doesn't resolve the issue, remove the ducting from the supply path and check if the unit can reach the selected flow by selecting MAX on the LCD screen. If it can, review the ducting path. If the problem persists, select the MIN and MAX flow setting values on the LCD screen, then reset the unit to display the MAX flow value. If the MAX flow is higher than desired, adjust the MAX and MIN flows. If the issue continues, replace the exhaust blower and repeat the flow setting steps. If all else fails, replace the electronic assembly.
