How do you preform a gas stove thermocouple replacement?
This Site Might Help You. RE: How do you preform a gas stove thermocouple replacement?
It's simple. A thermocouple looks like a 1/8 thick copper ( very flexible) rod that will be bent to fit into it's threaded holders at each end. Unscrew these ends and take it to a propane or gas store to have them replace it. (online identical ones cost from $20 to 85 dollars so shop wisely) Be sure to get the right length as they vary.If you want to buy it on line I suggest you try to find the manual for the stove. Generally it is a pretty generic part usually operating at around 25 milivolts. Anyway just notice how it was originally bent to get from one end to the other (a cell phone camera is good for this) in the stove. The new one will be the same. Screw in the ends and you are set. To turn the stove back on you generally need to light the oven pilot while depressing a red reset button for about a minute. Also, thermocouples are generally only in older stoves as newer ones have electronic switches as noted by others. Incidentially the person who said you have to replace the whole valve is mistaken. It is ALMOST ALWAYS just the thermocouple that is the problem (and I have built many kilns and ovens)
You cannot just remove the thermocouple. It is non repairable. You must replace the valve itself. The new part will not come preset. Place the old and new parts side by side and make the new part match(in height) with the old one. This will get you close to the same flame height. The new part will be cranked down to the bottom. They do this in case a propane replacement is made and I guess they do not want DIY'ers to start a fire. Repairing a gas stove is no more dangerous than you make it. Bubble test you connections. Take your time. You can do it. One other thing. Calcium buildup on the pilot can cause the thermocouple to fail because of weak flame. You can easily slide out the probe and clean the pilot with a soft bristle brush, replace the tip back in its holder and make sure the tip is in the heat of the flame. If the flame is washing through the probe body, then the dang thang won't work right.
