What No Heat
actually means.
On ABC7 combi ovens the time display shows No Heat when heating fails. Vulcan asks the owner to check the gas supply connection and then toggle the off/on switch to reset. The temperature display shows Err for a separate shutdown that also needs the switch toggled.

What to do when No Heat shows on the commercial applianceKind of codeIgnition 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.

Before you book,
in this order.
Each step comes from Vulcan's own guidance for No Heat on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Check that the gas supply valve is open and the quick-disconnect is fully seated.
Toggle the off/on switch to reset the oven, as Vulcan directs.
Note whether No Heat comes back at the start of a cook or partway through.
Book a visit if it returns, and do not open any gas fitting yourself.

What not to do
No Heat is not a steam or humidity problem; the humidity display shows its own Err for that. Any E number on the display is a separate service code that Vulcan asks the service provider to read.
