When to call a professional
If vents are clear and both filters are clean or replaced but the air flow SYSTEM ERROR persists, a fan or air-flow sensor may be at fault and should be checked by qualified service personnel. Contact your authorized service representative or Perfect Fry at 802-658-6600. Restricted air flow is a safety-related condition tied to ventless operation, so do not bypass the alert or run the fryer until normal flow is confirmed.
