When a fryer won’t light, the temptation is to “just get it going.†But gas equipment is one place where a safety-first approach matters. Here are safe, practical checks you can do — and the line where a technician should take over.
Safe checks your team can do
- Verify gas supply: Confirm upstream shutoff valves are open and other gas appliances are operating normally.
- Check the basics: Power switch on (if electric ignition), no tripped breakers, no obvious cord damage.
- Look for error indicators: Some units display lockout or ignition fault lights.
- Confirm ventilation: Poor draft/ventilation issues can cause safety lockouts.
What NOT to do
- Do not bypass safety switches or jump wiring
- Do not repeatedly attempt ignition if you smell gas
- Do not adjust gas valves/regulators without training
Common causes we see
- Dirty igniters or flame sensors
- Weak ignition modules or worn wiring
- Gas pressure/regulator issues
- Ventilation/airflow problems causing flame failure
