How to Really Test a Thermocouple 

Thank you for the support! and i couldn't agree more. if being meticulous means taking another hour to do a job, thats the only time i take situational awareness into account (how busy are we, is it worth the extra time, etc.) and say ok i "could" do it but its not worth it.

Thank you for the feedback, and thats a great tip! ill have to remember that one!

if its bad now, it will go bad again right!

You're right. Just replace that thermocouple instead of cleaning it. Sometimes a gas valve is stuck and if you tap, tap, tap on it, it will work but best bet is to replace those faulty parts. The parts may be going, going, but not yet GONE. Who wants a call back in 1-2 weeks for the same problem. Makes it look like the serviceman doesn't know what he is doing!...... If customer thinks the parts will somehow "heal" itself and get better over time, tell them it is not like a person getting a cut on their arm and over time heals on its own. The part is "aging out" or "aged out" Most customers can relate to those medical type terms!

Wrong. Maybe YOU don’t care but guys like me who are techs, and wear many hats, do care.

@@lowandslow3939 Hey slow down my friend, Just having fun here, I don't work on boilers I do heat recovery VRF and you need to be on point with planning and workmanship. We don't know the kids circumstances, how many jobs he has or what they are billing the CX. There are a lot of people that can't pay A-level service the cx drives the repair in what they can afford and we all do a little extra because we all care.

Hell yea 👊🏻 in the winter i always carry thermocouples on me where ever i go because i change them so frequently, saves me a lot of time going back and forth from the truck

@@theapprenticesurvivalguide yeah I carry a different tool load for winter too.

I'd have to look up the details, but it is the dissimilar metals that cause the electron flow. They use different combos for different specifications. Heating the junction causes more electron flow, that is seen as millivolts but it is the current flow that keep the solenoid pulled in.

thank you!
