Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: check whether an ignition click or spark is audible at all when it should be heating. Also, confirm the commercial range has power, any gas supply valve is open, and a simple reset — power off 60 seconds, back on — doesn't restore heat. Should that not clear it, no spark or flame usually means the igniter or gas valve itself has failed, and gas-carrying parts are restricted to licensed work in most jurisdictions.
