What happens when a thermocouple on a pilot light fails?
It consists of a heat sensor connected to a solenoid; when the sensor is not heated by the pilot flame, the solenoid closes the gas supply line. When a thermocouple fails, the pilot light won’t stay lighted. A burned out or broken thermocouple should be replaced. To replace a thermocouple:
Why does my pilot light not stay lit?
There is a chance that your thermocouple has simply gone bad and is the reason your pilot light won’t stay lit. If you’re fairly certain this is the source of the problem, you will either need to have the thermocouple replaced or repaired.
What happens when the pilot light goes out on a gas stove?
The thermocouple, which operates as a safety device, turns the gas supply off when the pilot light goes out. It consists of a heat sensor connected to a solenoid; when the sensor is not heated by the pilot flame, the solenoid closes the gas supply line.
What happens when a gas thermocouple goes out?
©2006 Publications International, Ltd. The thermocouple is a safety device; it shuts the gas off if the pilot light goes out. A faulty thermocouple should be replaced. Older gas appliances may have pilot lights that provide instant ignition when the gas is turned on. The pilot light is a small open flame that is fed by a steady flow of gas.

What happens if the pilot light is not lit?
Once the thermocouple detects that the pilot light isn’t lit, it turns the gas off as a safety measure. An unlit pilot can also stem from a dirty thermocouple as the dirt may be obstructing the current signal, which would also lead to a gas outage.
Why does my furnace pilot not stay lit?
The pilot won’t stay lit on my furnace, when I release the button it just goes out. This started occurring after I did some gas plumbing and had to relight the pilot. I suspected the thermocouple and replaced it, but this didn’t fix the problem.
How big should the pilot light be on a thermo couple?
The thermo couple tip should 3/8″ ABOVE the “pencil Pilot Tip”, should read about 30mv. 2. Once opened the burner door. Manufacture requires installing a new gasket around the burner door to prevent CO and air leakag.

Why is the pilot light on my water heater not working?
Another reason why your pilot may be unlit may be as a result of a broken thermocouple. If you check the thermocouple and it isn’t dirty, grimy, or curved, it may have been damaged. To confirm your suspicions, remove the thermocouple and test it with a multimeter.
Why does my gas heater pilot not stay lit?
The position of the thermocouple can be critical to its proper operation. The pilot flame must intersect the thermocouple for it to genereate the signal to tell the gas valve it’s okay to light. While it shouldn’t be a problem with a new one, if it is all covered in soot, that can be an issue.
What happens when a gas thermocouple is broken?
It consists of a heat sensor connected to a solenoid; when the sensor is not heated by the pilot flame, the solenoid closes the gas supply line. When a thermocouple fails, the pilot light won’t stay lighted. A burned out or broken thermocouple should be replaced.
