Confirm the fryer's gas valve is on and that any manual shutoff valve in the supply line is open. If it comes back, it needs a visit. ### How do I clear an ignition lockout on a Frymaster FilterQuick? Switching the controller off and on resets the attempt. If the burner locks out again with gas confirmed on, the ignition parts need a technician. ### Why does my Frymaster lock out after the gas line was moved? Moving the fryer can leave the quick-disconnect half seated or let air into the line. Reseat the connector fully, then try again; persistent lockouts need a visit. ### Should I relight a Frymaster FilterQuick by hand after E28? No. These burners light through an ignition module, not a match, and reaching into the burner area is not safe. Book a visit instead. --- **[Read on the site: Frymaster E28: the burner failed to light and ignition locked out](https://commercialappliancerepair.center/error-codes/frymaster-e28/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
