This motor is a Lamb Ametek Motor, initially Made in US, however new versions are are assembled in Mexico. This motor can be found in early S200, S300, S400 models. Please click on the image to enlarge and determine if you have the lip around the intake opening. Note that the other early US made motor (MI- 01502662) looks very similar to this except it does not have the lip. And again please remember we do not accept returns on motors. Therefore it is critical that you must order the right motor for your model.
