The easiest way to replace a bathroom vent fan is to keep the old housing and replace the fan and motor. Replacement kits designed for this purpose allow you to mount the new fan motor on a plate identical to the one that holds your existing fan motor.

So all you have to do is unplug the old fan from the housing, remove it from its mounting plate, then install the new plate with the new fan attached. Plug it in, replace the grill, and you’re done.

    My fan, apparently, is so installed that entire unit MUST be removed from attic side. What is a simplier fix?
