The Hobart 00-412788-00002 Thermocouple 48" measures the temperature at the flame and transforms the changes in heat into an electrical signal that is interpreted by the control system. The signal created by the equipment is used to detect the presence of the flame and regulate the flow of gas in its operation. The 48-inch lead length facilitates the routing of the sensing tip to the operator connection point. This is applied in foodservice equipment, where the temperature input is required to monitor ignition.

Customer Questions
What maintenance is required for the Hobart 00-412788-00002 Thermocouple?

Inspect the thermocouple regularly for heat damage, corrosion, or loose connections that can affect millivolt output. Keep the sensing tip clean from grease and carbon buildup to maintain accurate flame detection. Ensure secure mounting and proper alignment with the pilot flame. Replace if readings become unstable or response is delayed to maintain better gas operation.

What are common issues with the Hobart 00-412788-00002 Thermocouple?

  • Weak or inconsistent millivolt output causing shutdowns.
  • Pilot flame not properly detected by sensor tip.
  • Corrosion or heat fatigue reducing accuracy.
  • Loose or damaged electrical connections.
  • Carbon buildup on probe affecting signal strength.

Installation Steps

Step1: Switch off gas and electrical supply, then allow the unit to cool completely before servicing.

Step2: Open the access panel and detach the old thermocouple from the control valve and pilot bracket.

Step3: Route the new thermocouple along the original path, keeping it free from sharp bends or pressure points.

Step4: Secure the probe tip in direct pilot flame contact and tighten all connections firmly.

Step5: Restore gas supply, light pilot, and verify stable flame retention and proper shutdown response.
