A Pitco fryer is a trusted workhorse in many commercial kitchens. When the pilot light won’t stay lit, business slows down and stress rises fast. Fortunately, most pilot problems have clear causes and solutions. Whether you’re a chef, owner, or technician, understanding how to troubleshoot a Pitco fryer pilot can save time and money.
How A Pitco Fryer Pilot System Works
The pilot system in a Pitco fryer is designed for continuous ignition. A small flame (the pilot) lights the main burner when needed. If the pilot doesn’t stay on, the fryer won’t heat oil, causing downtime.
Key parts include:
- Pilot assembly: Delivers gas and supports the pilot flame.
- Thermopile: Senses flame heat and generates electricity to keep the gas valve open.
- Gas control valve: Opens or closes to release gas for the pilot and main burner.
- Igniter: Used for manual or electronic lighting.
When the pilot system functions correctly, the fryer operates safely and reliably.
Common Causes For Pilot Not Working
Most pilot issues stem from a few core problems. Here are the main reasons your Pitco fryer pilot may not be working:
- Dirty pilot orifice: Grease or debris can block the small opening, preventing gas flow.
- Weak thermopile: If the thermopile can’t generate enough voltage, the gas valve closes.
- Faulty gas supply: Insufficient or interrupted gas flow stops ignition.
- Bad gas valve: A failed gas valve won’t allow gas to the pilot.
- Loose or damaged connections: Worn wires or loose fittings can break the circuit.
Troubleshooting Steps
Solving a pilot issue is often straightforward with a methodical approach. Here’s how to troubleshoot a Pitco fryer pilot not working:
1. Check For Gas Supply Issues
- Ensure the main gas valve is open.
- Examine supply lines for kinks, leaks, or blockages.
- Verify the gas pressure matches Pitco’s specifications (usually 4″ WC for natural gas, 10″ WC for propane).
Pro tip: If other gas appliances in the kitchen work but the fryer does not, the fryer line may be blocked.
2. Clean The Pilot Orifice
- Turn off the fryer and let it cool.
- Remove the pilot assembly.
- Use a thin wire or compressed air to clear the orifice.
Even a tiny bit of debris can stop the pilot flame.
3. Inspect And Test The Thermopile
- Look for corrosion or bent wires.
- Use a multimeter to test for proper millivolt output (usually 400–750 mV with flame applied).
- Replace if readings are low.
Insight: Many new techs forget to let the thermopile heat for at least 60 seconds before testing.
4. Examine The Gas Control Valve
- Listen for a faint click when lighting the pilot—if silent, the valve may be faulty.
- Test input and output voltage if possible.
- Replace the valve if it fails tests.
5. Check Connections And Wiring
- Tighten any loose electrical connections.
- Replace damaged wires or connectors.
Quick Reference: Troubleshooting Comparison
This simple table shows common symptoms and the likely cause:
| Symptom | Probable Cause |
|---|---|
| Pilot won’t light at all | No gas supply, clogged orifice |
| Pilot lights but goes out quickly | Weak thermopile, faulty gas valve |
| Pilot flame is yellow or weak | Dirty orifice, low gas pressure |

When To Call A Professional
Some issues need a qualified technician. Call for help if:
- You smell gas (shut off supply immediately).
- The gas valve or thermopile needs replacement and you lack experience.
- Problems persist after basic troubleshooting.
Attempting complex repairs without training can be dangerous.
Preventive Maintenance Tips
Regular care keeps your Pitco fryer running smoothly and prevents pilot problems.
- Clean the pilot assembly every month.
- Check connections for wear every quarter.
- Test the thermopile twice a year.
- Schedule professional service annually.
These simple steps reduce downtime and repair costs.

Pitco Fryer Models: Pilot System Differences
Not all Pitco fryers use the exact same pilot system. Here’s a quick comparison of popular models:
| Model | Pilot Type | Main Difference |
|---|---|---|
| SGL35/45 | Standing pilot | Manual lighting, common in older kitchens |
| SE14 | Electronic ignition | Auto relight, fewer pilot issues |
| SSH55 | Standing pilot | Heavy-duty, similar troubleshooting steps |
Note: Electronic ignition models often show error codes. Always check your owner’s manual for model-specific tips.
Safety First: Important Reminders
- Never bypass safety devices to force ignition.
- After any repair, test for gas leaks using soapy water.
- If unsure, contact Pitco support or a licensed professional.

Frequently Asked Questions
Why Does My Pitco Fryer Pilot Light Keep Going Out?
A weak thermopile or dirty pilot orifice is usually the cause. The thermopile may not generate enough power to keep the gas valve open, or debris may block gas flow.
How Do I Test A Thermopile In My Pitco Fryer?
Use a multimeter set to millivolts. With the pilot flame on, a working thermopile should produce 400–750 mV. If the reading is low, the thermopile needs replacement.
Can I Clean The Pilot Orifice Without Removing The Assembly?
It’s best to remove the pilot assembly for thorough cleaning. Blowing air through the orifice in place may not clear all debris and could push it deeper.
What Should I Do If I Smell Gas Around My Fryer?
Turn off the gas supply immediately and ventilate the area. Do not attempt to light the fryer or fix the leak yourself—call a professional.
Are Pitco Fryer Pilot Problems Common?
Yes, especially in busy kitchens where fryers run all day. Grease buildup and normal wear can lead to pilot issues, but regular maintenance helps prevent them.
A working fryer means happy customers and less stress. Understanding your Pitco fryer’s pilot system gives you the confidence to solve problems quickly—or know when to call for help. With the right approach, most pilot issues are easy to fix and prevent.
