How do you know if you have a bad thermocouple?
If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube.

How much does it cost to replace a thermocouple?
The No. 1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10.
Is it dangerous if your pilot light goes out?
Can a Pilot Light Outage Be Dangerous? The worry here is that when a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be pumping gas. This can mean a buildup of gas, and when the pilot is relit or relights itself it could result in a very serious explosion.
Why does my hot water only last a few minutes?

Will turning up water heater make hot water last longer?

What causes a thermocouple to go bad?
The presence of oxygen causes a reaction in the thermocouple that can wear down the part and make the wires become thinner and more brittle. Oxidation can be caused by a small amount of oxygen making its way into a sealed environment and reacting with the pure metal of the thermocouple.
What would cause a pilot light to keep going out?
Usually, a problem with the thermocouple causes the pilot light to go out. The thermocouple is the small copper rod that the pilot light hits. The thermocouple’s job is to shut a gas safety valve if the pilot light goes out. That’s important because gas is always being supplied to the pilot to keep the flame lit.
Why does my hot water keep running out?
Water Heater Runs Out Of Hot Water Quickly: Possible Reasons Why. As mentioned above, several things can cause a home’s hot water supply to run out faster than it should. The three most common culprits are sediment build up, a faulty heating element and a broken dip tube.

Why will my pilot light not stay lit on my water heater?
If your gas water heater doesn’t stay lit, you may have a defective thermocouple. Most gas fired water heaters use a standing pilot to ignite the main burner. … The thermocouple is a heat sensing probe that is part of the pilot assembly and sits just above the pilot flame.
