Diagnosis and Testing
Technicians start with a full visual inspection then move to multimeter checks on igniters, thermocouples, and temperature sensors. Gas pressure is verified at the manifold while door alignment and latch tension are measured. Control boards receive voltage and continuity tests before any parts are ordered.
Common Failure Symptoms
Ranges may fail to ignite on one or more burners, show uneven heating, or display error codes on the control panel. Ovens can run too hot or too cold, produce clicking sounds without flame, or trip breakers during preheat. Slow recovery after door openings often points to failing door seals or convection motors.
Repair vs Replace Considerations
When the unit is under ten years old and the main chassis is solid, component-level repairs such as valve or board replacement usually make sense. Older units with widespread corrosion or discontinued parts often favor replacement once repair costs approach half the price of a new commercial model.
What to Prepare Before Service
Clear a three-foot workspace around the equipment and note any recent error codes or changes in performance. Have the model and serial numbers ready and confirm whether the appliance runs on natural gas or propane. Kitchen staff should know the last service date and any parts already replaced.
Technician insight
In Spokane the thing that catches most people out with Commercial Range & Oven Repair is how older downtown buildings with single-wall gas lines react to our deep winter temperature swings. Valves that test fine in summer can stick or leak once the mercury drops and the line contracts. Checking supply pressure and line condition first often prevents unnecessary range disassembly.
No Ignition on Left Burners
A commercial range in a Spokane restaurant lost ignition on two left burners during lunch rush. Testing showed voltage reaching the igniter but no spark due to cracked ceramic insulation. The igniter assembly was swapped and the manifold pressure rechecked. Both burners lit reliably and the kitchen resumed full service the same afternoon.

How it works
- 1
On-Site Assessment
Technician reviews symptoms, checks model details, and confirms power and gas supply before any disassembly.
- 2
Component Testing
Igniters, valves, sensors, and boards receive live voltage and continuity checks to isolate the exact failure.
- 3
Repair or Recommendation
Parts are replaced on the spot when available; otherwise a clear repair-versus-replace option is presented with parts pricing.
- 4
Function Verification
Full operating cycle is run to confirm ignition, temperature accuracy, and safety shutoffs work correctly.
Pricing
Cost varies with parts availability, whether gas or electric components are involved, and the time required for access in tight commercial spaces.
