Similarly, are hot water heater thermocouples universal?
From an operational perspective the thermocouples for a water heater are all pretty much the same. However, there are two variables, the length and the fittings used to install them, see below. A failing thermocouple will not send the correct electrical impulse and the gas valve will not release any gas.
Similarly one may ask, can a water heater thermocouple be cleaned?
Clean the thermocouple – using the emery cloth sandpaper, sand the ends of the thermocouple and then give it a finishing touch with the lint-free cloth. Hopefully, you can get to the ends of the thermocouple without having to detach it from the assembly, but you may have to do that.
Do all water heaters have thermocouples?
Not all gas water heaters have a thermocouple. Some newer models have an advanced temperature control system. Essentially, it is a microprocessor that constantly monitors and controls burner operation and maintains consistent and accurate water temperature levels. The flashing LED indicates that the pilot is on.
How do I choose a thermocouple?
How to choose a Thermocouple
- Determine the application where you will use the thermocouple sensor. …
- Determine the temperature ranges the probe will be exposed to. …
- Determine how important a fast response time is. …
- Consider any chemical, abrasion or vibration resistance. …
- Consider any installation requirements.
How do I know if my thermocouple is bad on my water heater?
If the pilot lights but the flame goes out as soon as you release the button after holding it for 60 seconds, then the thermocouple is bad. It’s possible to replace the thermocouple without removing the burner assembly, and many repair people do this.
How do you replace a thermocouple on a hot water heater?
How do you test a thermocouple on a AO Smith water heater?
How long do thermocouples last?
Thermocouples can last up to 10 years if properly installed and maintained, while furnaces can last 15-20 years, although either may wear out sooner in multifamily units.
How much should a plumber charge to replace a thermocouple?
Thermocouple Replacement Cost
Calling a professional plumber to install a new thermocouple should only be up to $150. If you do the work yourself, you will only pay the price of the part which is about $20.
Will a pilot light stay lit with a bad thermocouple?
A thermocouple senses the heat of the pilot and allows gas to flow to the burner. A bad thermocouple will shut off gas to both the pilot and the burner so the pilot light won’t stay lit.
