Most of the time water heaters are mostly out of sight and taken for granted, until they fail to work properly. Then the lack of hot water brings this normally obscure appliance to the center of attention and often leaves its owner asking why my water heater won’t ignite. Ignition problems are often related to a faulty thermocouple.
This is the device whose tip is normally enveloped in flame and kept hot when the pilot is lit. In gas heaters, the thermocouple controls the gas supply and when it is not working properly, it can signal the gas to shut off which shuts the pilot light down. Thermocouples are inexpensive and replacing them is not a complicated job, however it is vital that the replacement part length is an exact match for the part being replaced.
