No hot water? If the pilot flame in your water heater keeps on going out or won't stay lit, then it could be a problem with the thermocouple or thermal cutoff switch. In this episode of Repair and Replace, Vance shows how to troubleshoot the pilot flame in a water heater with a conventional gas valve. This includes testing the thermocouple voltage with a multimeter and checking the thermal switch for continuity. This can help troubleshoot a water heater that is not heating water.
In an open circuit test, a healthy thermocouple should produce 20 - 30 millivolts DC. If the reading is under 20 millivolts, then the thermocouple should be replaced. Learn how to replace the thermocouple in this video: [ Ссылка ]
