FireBoard 6-Foot Probe Extension Cable — Frequently Asked Questions
What is the FireBoard 6-Foot Probe Extension Cable?
The FireBoard 6-Foot Probe Extension Cable (PE121) is an accessory that extends the reach of your FireBoard ambient or food probes by 6 feet — perfect for larger grills, remote probe placement, or setups where the standard cable isn’t long enough.
Which probes is it compatible with?
It works with both **Thermistor** and **RTD** probes (ambient and food types) that FireBoard uses.
How do I use the extension cable?
Plug the extension cable inline between your existing probe and the FireBoard controller. Run it to the desired location, ensuring that it’s protected from excessive heat, sharp edges, and potential pinching. You may chain multiple extensions for even greater reach—FireBoard documentation notes that this works best with Thermistor type probes.
What are the advantages of using it?
• Greater flexibility in placing probes (e.g., into deep smokers or across wide setups)
• Helps keep the FireBoard controller further from heat or smoke
• Avoids strain on probe cables or awkward routing in tight grill spaces
Are there any limitations or best practices?
• As with any extension, each added junction can slightly degrade signal — keep connectors clean and tight.
• Avoid routing extension cable too close to high-heat zones or direct flame.
• Minimize cable stress (kinks, sharp bends) which could damage internal wiring.
• Using many extensions in series works better with Thermistor probes than RTD per FireBoard’s guidance.
