Vulcan ovens are known for their reliability, but like all commercial kitchen equipment, parts wear out. If your oven isn’t lighting or holding temperature, it might be time to replace the thermopile or ignitor.
Common Symptoms of a Bad Thermopile or Ignitor
-
Oven won’t stay lit
-
Pilot light flickers or goes out
-
Delayed ignition
-
Uneven cooking temperatures
How to Troubleshoot
-
Check the pilot light stability
-
Use a multimeter to test thermopile output (<300mV = replace)
-
Visually inspect the ignitor for cracks or corrosion
Replacement Tips
-
Always match model numbers (e.g., VC4ED, VC5G)
-
Replace gaskets at the same time for proper seal
-
Use OEM or certified parts to avoid warranty issues
