If the water heater is not working properly or the water is not heating up, you must test the water heater’s thermocouple for any damage.
- The first step includes removing the water heater thermocouple.
- Next, you must turn on the meter and set it to Ohms.
- By touching the two leads together from the meter, you will get a reading close to zero. If you take the leads apart, your meter reading will be infinity. This is a simple task for checking the meter’s continuity.
- After this, you can turn the meter to volts.
- Start the flame of the water heater and carefully put the tip of the thermocouple in the fire.
- You must ensure that the tip gets well heated from the flame.
- Now take one lead from the meter and put it on the shaft of the thermocouple, while the other lead must be kept on the end of the thermocouple where it makes contact with the gas valve.
- If your meter’s reading is less than 25 millivolts, you must replace your water heater’s thermocouple because most standing pilot gas valves require 25 or more millivolts to keep the pilot flame lit.
- When the pilot flame does not stay even after the ignition button is released.
- When you experience a pilot outage.
