b) Set a voltmeter to the 300 volts scale. Place test probes on terminals 1L and 3L (see diagram) of the high limit portion of the thermostat. The meter reading should be the input voltage of the heater (see rating plate of the water heater). If not correct voltage, check for loose connections and blown fuse or tripped circuit breaker. c) To verify that the high limit switch is closed, place test probes onto terminals 2L and 4L (see diagram).
Your water heater usually has two elements and two thermostats. The upper thermostat has two functions. First it allows the upper element to heat the water in the top of the tank. When this water is hot enough it shuts the upper element off.Then it allows power to go to the lower element.Make sure that the power is off.o light, time for a new thermostat. To check the lower thermostat you need the upper thermostat turned off. The lower thermostat needs to be turned to its highest setting. This should insure that lower thermostat is allowed to engage. Use the water heater tester to check terminals #1 and #2 (the lower set).
