took my chances with this as wasnt sure if it would fit into my 10 year old cooker hood. I decided to deep clean the cooker hood one day including the motor, using degreaser. as a result i damaged the motor which would only opperate on the 2nd and 3rd speed. tried this motor, slightly more powerful, at the start it wouldn't work due to the difference in wiring but got it working eventually. took almost a month and a bit to arrive, other than that, i;m happy
