How much should it cost to have thermocouple replaced on a hot water heater?

Let me see, you will have about a 65 dollar service call just to get them to your house. Then you will have a labor (most bill by 1/2 hour) so you will have about 25 or 30 dollars for that. And then maybe 10 to 15 for the part.

So you have about 100 to 110 dollars rough estimate.

Of course you can go to the hardware store, buy one and put it in yourself fairly easy

Chuck is right. You might get away for less than that, but not much less. A quote from another answer I just gave: ''Tom knows how plumbers do things. He knows exactly how to make the right tool work, and had it on his truck. That is part of being a pro.'' Training, experience, tools, parts, and a truck to haul them don't come cheap.

Thermocouples do. You have a nut at one end and maybe a screw or 2 holding it in place at the other end. You can see a picture of one in the Heating and cooling sticky at https://www.askmehelpdesk.com/heatin...ons-58313.html
It won't hurt to take the old one with you.

$65.00 an hour?

You need to get out more often, FC.

Labmans right -- If you have the wherewithal to replace it yourself, then you should do so.

Suqj needs to tell us where he lives and if he wants a pro or is he asking a DIY question. He really has not made that clear in his question.

No, that is a common labor rate in Missouri, Georgia and Tennessee.

I was merely using the labor rates I use now when I am doing any service work again. We have a 65 dollar service fee and then our hourly shop rate for labor is 60 dollars. I do a 1/4 of hour min myself but some have a one hour min.

I actually change thermocouple on commercial gas equipment so yes if our company came out it would be in that 120 to 150 range by the time we got done.

I think that is just what the OP wanted to know. I also think we did well to suggest a DIY project. Changing a thermocouple would be a good first project and save a bundle.

True, it is probably the easiest fix I can think of that would cost over $100 for a pro to complete. It is very close to replacing a faucet washer in level of difficulty and cost.
