Gaylord exhaust hoods maintain air quality and ensure kitchen safety. Although issues with these units are rare, these Gaylord exhaust hood troubleshooting tips will help you solve issues with your unit quickly and easily.
These directions are for EL, ELX and ELX-UV series models.
Ventilator Not Exhausting Properly
- The fan isn’t performing properly / a Gaylord balancing damper isn’t adjusted properly - Call a licensed technician to remedy the issue.
- Heavy grease accumulation in the filters/extractors - Remove the filters/extractors and check for grease accumulation. If there is grease buildup, clean the filters/extractors.
