Easy replacement, grill's working again

My old thermocouple died and this one fit my 4 burner Sunstone grill perfectly. 53" was just right, no stretching and no extra slack. Install was straightforward and the grill fires up every time now. Good to have it working safely again.

Solid Thermocouple for Sunstone Grill

Needed a replacement for my 28-inch Sunstone gas grill, and this thermocouple did the trick. It feels well-made, and the connection points were identical to the original. My burners are staying lit without any issues now, which is exactly what I needed for my weekend cookouts.

Debbie D.★★★★☆January 29, 2026
Good Value, Works as Expected

For the price, this thermocouple is a solid buy. It fit my 5-burner Sunstone grill perfectly, and the 53-inch length gave me plenty of room to route it properly. No more frustrating relights, the flame sensor is doing its job. Happy with the purchase.

Julia C.★★★☆☆August 10, 2021
Decent, but a bit fiddly

The thermocouple works, and it did get my 3-burner grill back in working order. However, getting the nut tightened in place was a bit of a tight squeeze, even with the 53-inch length. It's functional, but the installation could have been smoother.

Cameron N.★★★★☆January 3, 2010
Fixed my grill staying lit

My 34" Sunstone grill wouldn't stay lit and after some troubleshooting I figured it was the thermocouple. This was what I needed. Direct fit and now the grill runs like new with a steady flame. Very happy.

Questions & answers

5 questions answered

Q
I'm not very handy. How hard is it to install this thermocouple?Asked by Sunstone Support Team
A
With basic DIY skills it's usually straightforward. You disconnect the old thermocouple and carefully attach the new one, making sure every connection is secure. Check your grill's owner's manual for your 28" or 34" model, since some have slightly different access points.

Q
Will this 53 inch thermocouple fit my older Sunstone 4 burner?Asked by Sunstone Support Team
A
It's made to fit a wide range of Sunstone 3, 4 and 5 burner grills, specifically the 28" and 34" sizes. The 53 inch length gives plenty of slack for different routing inside those grills. If your grill is in that burner and size range, it should work as a replacement.

Q
Does the thermocouple need any cleaning once it's installed?Asked by Sunstone Support Team
A
Very little. Every so often, look at the tip for carbon buildup and gently wipe it off with a soft cloth if you see any. Don't use harsh chemicals or anything abrasive, they can damage the sensor. Keeping the whole grill clean helps all the parts last longer too.
