We just got our ovens and so far are very pleased.  However we made the mistake of purchasing the air fryer part.  We have 27" ovens and they sent the one for the 30" ovens.  When we called 
Frigidaire they said we had to contact Electrolux who provides that part.  After 1/2 hour on hold they could not find the order and it went to the survey followed by a hang up.  Very frustrating!
