Our gas fryer pilot was staying lit, but the burners wouldn't kick on. We were having trouble keeping up with orders during a busy shift. The technician came out, checked the ignition system, and found an issue with the thermopile. He explained what was going on and got the fryer heating properly again. Really appreciate the quick response and professional service.

About the Service Call

‍

Imagine a busy restaurant kitchen during dinner service. The fryer pilot is burning, but the main burners refuse to light.

The oil temperature keeps dropping. Fries take longer, chicken comes out inconsistently, and the kitchen staff can't keep up with orders.

The first instinct may be to replace the gas valve. But that isn't always where the problem starts.

‍

‍

Diagnosing the Problem

‍

Our technician begins by checking the pilot flame, thermostat, thermopile output, electrical connections, and gas safety controls.

On compatible millivolt-controlled fryers, the thermopile generates the electrical power needed to operate the gas valve.

If its voltage drops too low under load, the pilot may remain lit while the main burner fails to open.

A weak pilot flame, damaged connection, faulty thermostat, or defective gas valve can produce similar symptoms.

That's why our team tests the entire ignition circuit rather than guessing which part has failed.

‍

‍

How Our Team Handles the Repair

‍

When testing confirms a weak thermopile, our technician replaces the defective component with a manufacturer-approved part.

We also inspect the pilot assembly, verify flame contact, examine electrical terminals, and test the gas valve's response to the thermostat.

After completing the repair, our team checks burner ignition, flame stability, operating temperature, and the fryer's normal heating cycle.

The goal isn't just to make the burner light once. It's to confirm that the fryer heats consistently and its safety controls operate correctly.

‍

‍

Warning Signs to Watch For

‍

  • Pilot flame stays on, but burners won't ignite
  • Fryer stops heating during service
  • Oil temperature falls between batches
  • Burner ignition becomes intermittent
  • Thermostat calls for heat without a response

If you smell gas, stop using the equipment and follow the manufacturer's emergency instructions. Never bypass gas safety controls.

‍

‍

Why Proper Diagnosis Matters

‍

Replacing a complete gas valve when only a thermopile or electrical connection is faulty can increase repair costs unnecessarily.

Our team focuses on finding the cause before recommending parts.

A properly diagnosed ignition issue can mean less downtime, more predictable cooking temperatures, and fewer interruptions during busy service.
