All you want is for your water heater to give you hot water so you can shower, wash dishes, and go about your everyday life and chores. Is that so much to ask? But when the pilot light goes out constantly, you don’t have those comforts and it can be rather frustrating. There are a number of reasons why pilot lights go out and all of them depend on a number of different factors. When it comes to water heater repair, you are always better off getting professional help. However, understanding what’s happening behind water heater repair is never a bad idea for any homeowner. Here are a few reasons your water heater pilot light may not be able to stay lit.
Reason 1: An Obstructed Thermocouple
Most water heaters operate using a thermocouple. The device controls the operation in a central manner and it can tell when the pilot light is lit or not based on an electric current that gets power from the pilot light. When the thermocouple detects the pilot light is out, it turns off the gas as a safety precaution. If the thermocouple is dirty, the current it gets from the pilot light might be obstructed, which will make the gas turn off. You can fix this by cleaning the thermocouple, but you will want to have the gas off and call a professional to help with the job.
Reason 2: Curved Thermocouple
Even if a thermocouple isn’t dirty, it can be too far away from the pilot so it won’t register the heat. It can be bent back so it is closer to the pilot flame, which should lightly touch it or be close enough to heat the device.
Reason 3: Damaged Thermocouple
If the thermocouple isn’t bent or dirty, it can still be damaged or simply broken. It might have to be replaced or repaired in order to operate normally again. The water heater needs to have the gas off and the thermocouple needs to be cool before repairs or replacements can take place.
Reason 4: Dirty Pilot Tubes
If there are no problems with the thermocouple, the pilot tube might be dirty, blocking the proper flow of gas. The tube will simply need to be cleaned out to give the gas a clear path.
Reason 5: Flex Tube Issues
Flex tubes connect the gas controller to the stream of gas. If the tubes get kinked, they can prevent proper operation. Unkinking the tubes might do the trick, but if it doesn’t, there might need to be new tubes as part of water heater repair.
