In a Ventline RV range hood such as # S0721-20BD-F-1 you will want to remove the grease filter to access the damaged motor to install a replacement like # BVD0278-00 which uses AC power or # BVD0218-00-R which uses DC power. Of course, make sure power is disconnected.
We do not have a video showing the process but I was able to obtain from Ventline the written instructions for motor replacement for DC and AC motors. These have been forwarded to you in a separate email. view full answer...
