$18,000 - $20,000. More than $20,000. The total amount spent per pupil by district in the 2011-12 school year by elementary and K-12 districts. The darker the color, the higher the spending.
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).
To work properly the electric water heater thermostat needs to be positioned firmly against the wall of the hot water tank. It is held in place by a spring steel bracket. There are no screws that actually hold it in place. You have followed Steps One and Two, so the power is off and the cover plates have been removed.
