#12 Hot water system pilot light won’t stay lit
The video below runs over the task of changing a faulty thermocouple to get your hot water system working again. This is a relatively simple task to do yourself, however, if you don’t feel comfortable or if it requires pulling the whole burner out, reach out to Yates Plumbing and Gas for help!
Firstly you shut the gas off to the unit. If the pilot light has been on and this is a maintenance thing, make sure you let it cool as it will be hot. This is typically done after it’s cold and can’t light it.
Then open the outer and inner door. Determine if the thermocouple needs to be replaced. This is not a difficult task but if you need to replace the burner then we recommend giving us a call to help.
Put wrench on and spin off, one turn to pull out and down. Then put your finger on the end, twist and pull out. The new one should be the same – they are universal.
Then reverse the process. Slide it into the hole and give it a twist while you push it in. Simply push back into gas valve and wiggle to thread making sure you are not cross threading it. If it doesn’t twist easily you are cross threading.
Tighten with wench 90 degrees and make sure there is not much shaft wiggle – if there is, tighten a little more. Then light the pilot light – turn on and depress button. Hold button down for minute or so then release and make sure the thermostat is in pilot mode.
Turn fire up past the click then turn it back off and reverse process on doors to put both doors back on. Make sure to set the thermostat to the setting you had before.
