Wolf's troubleshooting ties a light still lit after three trials to no gas supply. Wolf Commercial commercial appliance display · also shown as IGNITION Light (Red) What to do when IGNITION light shows on the commercial appliance ### Kind of code Ignition and gas The unit tried to light and never proved a flame, or lit and then lost it. On a fryer, a griddle, a combi or a gas tumbler the ordinary reasons come first: the gas valve at the unit left partly closed after cleaning, a quick-disconnect hose not fully seated, an igniter crusted with grease or lint, a flame sensor or thermopile that no longer reads the heat, or a draft from a hood or a door pulling the pilot away. Checking the valve and running the reset the manual names are fair; if you smell gas, get everyone out first, and the gas valve, the sensor and every fitting stay with a technician. ### Usually leads to Commercial cooking line gas repair Griddles, charbroilers, restaurant ranges and hot tops: pilots, burners, orifices, valves and hoses, leak-checked after. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Wolf Commercial Wolf Commercial equipment on a restaurant line is serviced when the station can be shut for a while, usually between services. ### Source Wolf WC4G gas convection oven installation and operation manual, form 51059 rev.

Turn the oven off with the Master Switch and wait five minutes before trying again, as Wolf directs. If it comes back, it needs a visit. ### Why is the red light on my Wolf convection oven staying on? The oven tried to light its burner and did not prove a flame. The first thing to rule out is the gas supply to the oven. ### How many times can we retry lighting a Wolf WC4G? Wolf describes waiting five minutes between tries and giving it three trials. After that, turn off the gas to the oven and book a visit. ### Is the flashing red light on a Wolf oven a problem? No. It flashes while the oven is lighting. Only a light that stays on means the burner failed to ignite. --- **[Read on the site: Wolf convection oven red IGNITION light stays on: the burner did not light](https://commercialappliancerepair.center/error-codes/wolf-commercial-ignition-light/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
