Thermocouple Replacement Procedure
Turn Off The Gas Supply
Before you start any type of electrical work, you need to make sure that the gas supply or the power supply to that appliance is put off. This will let you work under safe conditions and prevent major accidents.
Remove The Nuts
When you have turned the gas supply to the water heater off, you will have to unfasten the three nuts that hold the thermocouple and the two gas tubes to the valve. Once you have done this, the burner that just sits loosely will easily be able to slide out.
Detach The Thermocouple
In most of the hot water tanks, the thermocouple is attached to the pilot gas supply tube with the help of one or two clips that snap into place. The end of the thermocouple will be inserted into the pilot assembly. You will just have to pull it out. This spoiled thermocouple is of no use to you anymore.
Install a New Thermocouple
You have to install the new thermocouple in place of the old one. You will have to attach the end of the new thermocouple into the pilot assembly and reattach the thermocouple to the pilot gas supply with the help of the clips that you removed previously. Then you can reinstall the burner with the help of an adjustable wrench, reconnect the thermocouple lead, the pilot gas tube to the valve, and the gas tube to the main burner.
Turn The Gas Back On
Once you have put everything back in its place, you can turn the gas supply back on. When the gas supply is on, follow the lighting instructions on the water heater.
Following these steps will help you to replace water heater’s thermocouple easily and appropriately. If you have never done any such work in the past, you should not attempt to do this and call professional plumbers in Edmonton instead. This way, you will have to bear a little expense but at least you will be saved from major accidents.
