Some things to consider before purchasing a grill hood thermometer:
First is the size of the face and the best way to do this is to remove your existing grill hood thermometer and measure across the hole in the bezel that it came out of. Like most grill hood thermometers this thermometer will not sit flush against the hood and the bezel not only makes it look better it also stabilizes the face. This particular Tel-tru grill hood thermometer has a 2 inch dial face this will fit most grills.
The next thing to consider is the length of the threads on the back of the thermometer. This is to ensure that they are long enough to be able to tighten the nut. when you install the new one. Simply measure the threads on your existing thermometer for this. It is acceptable for the threads of your replacement to be long but not short. The threads on the Tel-tru grill hood thermometer are just under 3/4 of an inch long.
The final thing to consider is the length of the probe. The stem length on this one is 2.25 inches. That measurement is from the thermometer back including the threads.
To remove your existing grill thermometer: Raise the hood of your grill and look at it from underneath. On most grills you will be able to see the thermometer stem and a nut. Find the appropriate tool to loosen the nut and while putting slight pressure on the dial from the outside turn. Once it is a little loose you can hold the nut by hand and turn the dial from the outside to remove it all the way.
Installation of your new grill hood thermometer:
If you took your measurements right, installation should be easy as placing your new grill hood thermometer into the hole and tightening up the wing-nut from the back. It only needs to be hand tightened. Before you fully tighten the nut make sure the face of the thermometer is straight up and down and apply a little pressure to the face when making that
