$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).
Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.. Remove the two wires connected to the water heater element and push them aside. Unscrew the mounting hardware with a screwdriver, slip the wires out and bend them out of your way.
