how-to step one
check electrical panel to be sure that circuit breaker is in the on tuesday not been tricked or off or fuses diffused are installed securely and not alone reset circuit breaker to honor replace any twenty years as and wait thirty sixty minutes for water to war if water has remained cool continue troubleshooting steps below:
shut off power shut off power in the electrical panel by removing fuses or by moving to handle a switch or circuit breaker dedicated to the water heater to the opposite completely removing pocket confuses or otherwise secure or locked the panel in place a note on the cover to alert everyone can work is being performed on the water heater circuit this will prevent the accidental energizing of the circuit while you are working on i.
remove the upper and is provided lower access panel past use of all time your test writes a cheque between wiring terminals and grounded metal case if it had to be sure cut the power is off rock art or secure the circuit breaker or remove fuses to prevent someone from turning a circuit on while you were working on the water heater.
clear away any insulation blocking access or view of the controls thermostat and high temperatures which and heating element
look for obvious signs of damage water heaters can leak water as a result of a fill in tact but also from poorly fitted or sandra cold water supply pie and hot water output type if the lower to leak it can cause damage to internal components of the controls if water enters them dot rust coats liars and controls both outside and inside dot the russes conductive even win on the wire insulation this can lead to potentially deadly shocks keating and melting insulation and even burns sony black carbon deposits on surfaces indicate a short circuit chances are there is an exposed copper wire that may be difficult to see you due to the carbon deposits that resulted from the short-circuit dot the yellow wire between the control an element appears to have shortage of the time or other lateral leaving the city black deposit underwire and above notice the lower left terminal a thermostat excessive heat has caused the plastic around the terminal to begin to melt dot wires may have been damaged and now have a smaller circumference then needed to carry that heating element electrical load at this point of damage is also a source of heat it is very important to repair or replace all parts zippel forms of water in short circuit damage this includes wires wire insulation jumpers and at the controls themselves as mentioned above rosty’s a conductor and provides unintended has for electricity these unintended class can be dangerous in make troubleshooting very difficult to perform .
locate the parts the local in high temperature limits which has reset button like the red and four carol’s three of which are numbered and visible in the picture number one number three and number four and the number two terminal is not identified as it is connected directly to the thermostat below via jumper high temperature limit switch has the reset button there will be for terminal screws wires connected to it usually the top two terminals have wires that go up to the field wiring compartment did bring the power to the rest of the water heaters controls and heating elements studio perkins roles consist of the high temperature limits which and upper thermostat the lower controls refers to the lower thermostatic there is no high temperature limit switch for the lower section of most electric water heaters.
test to ensure it power is off centimeter forty c volts and insert the black probe into the black or common jack and the red coat into the red boreholes jack.
measure voltage set the a c voltage range to the highest available touched up roads to the top terminals at the high temperature limits which as shown in the image to the right to range maybe lowered to any desired provided the range is greater than the voltage is played at the highest range able to prove power off double-check circuit panel do not receive unless our is prove off otherwise damage coming here is likely in shock or burns is possible in the steps to follow.
set them alternator to loans or resistance observed earlier indication if enamel on-site the new york pointer will be resting delivered a higher resistance values leftmost position this is an open circuit indication if digital mirrors used it may display hill a lower one one without trailing or leading zeros this oil or one indication represents a value greater than the meter is capable of displaying similar to that way calculator does for overload or infinity infinity in high resistance range is also called an open circuit or open-loop or l take note of this open circuit indications for this mirror women a voltage or current ranges selected and the mir displays a lower one the measurement should be taken again after adjusting the range upward.
If you are unsure what your leader should read in the noel situation just leave the terminals unconnected to anything and not touching each other and switch the mir on it should be done indicates the resistance of the air between the terminals which should be infinitely in normal conditions .
remove one wire from the heating element it does not matter which.
connector black test lead to the track marks comin .
connect the red test lead to the jack martin is or resistance if there are multiple jack’s from which to choose.
septa range if provided to iraq’s one if any are being use does not provide for range selection is likely to model ranging type this simply means that the mir will automatically adjust the range up or down as needed without any intervention by the user this teacher is far more common digital meters men along types most analog meters they do not provide manual range selection likely support only a single range these meters are much more accurate indicating little values such a zero three five hundred k or one and mom’s than higher values says those above or a m but will work well for dis procedure paying close attention to the display of the model ranging digital near when reading there is a huge difference between twenty twenty ten twenty am arms .
Data indicates thousands and uh… nam indicates millions the examples of of would correctly reread as twenty homes twenty thousand ohms twenty kaelin’s or twenty kilo homes and twenty million owners twenty-nine realms or twenty million homes he choose one thousand times larger than the previous
press the metal tips of the test probes together vienna one-year pointer should move to lois values of the resistance gail or fully to the right the digital mere should indicate zero ordinary low value approaching zero locate zero just not concerned so that the linear indicates the road or as close to zero as possible most digital leaders do not have this zero adjust feature one zero nine this neo position on the dial is the short circuit or zero ns indication for this range of this leader the mir must be zero to the resistance range is changed measures resistance values will be inaccurate but unable to properly zero the meter .
replace batteries if needed if unable to obtain as your own indication on an analog neither this may mean the batteries are weak and should be replaced retry the zeroing step of all began with fresh batteries digital meters often graphically displayed the batteries level of discharge or simply an indication to replace the battery check the mir manual for helping to terminate the battery charged.
press the protests against the terminals of the heating element one probe to each group red commuter display look for range multiplier.
