After you have the thermocouple eliminated, you can begin testing it.
To check the thermocouple, you may want to make use of the multimeter. Set the multimeter to the millivolt setting. Then, contact the probes of the multimeter to the terminals of the thermocouple. If the thermocouple is working correctly, the multimeter will learn between 20 and 30 millivolts. If the thermocouple isn’t working correctly, the multimeter will learn 0 millivolts. If the thermocouple isn’t working correctly, you’ll need to switch it.
Tips on how to Take a look at a Water Heater Thermocouple
A thermocouple is a security machine that shuts off the fuel provide to a water heater if the pilot mild goes out. Over time, thermocouples can change into defective and must be changed. Listed below are the steps on find out how to take a look at a water heater thermocouple:
- Flip off the fuel provide to the water heater.
