I switched off the power prior to looking at this, i did not wire it. landlord replaced thermostat yesterday after the heating element had already been replaced2xs now, 0 hot. heater model 71-40sb


Is this a 220 VAC H/W Heater or a 120 VAC H/W Heater?
Note: Info provided here is for a 220VAC H/W Heater
Thermostat doesn't look like a new one, maybe it is used!
Check input power (voltage) on top two wires if this is a 220VAC H/W Heater ... then the input power from the C/B in the Electrical Panel should be 220 VAC. If 220 VAC power is not present on the top two wires ... you may have a bad C/B in Electrical panel. Make sure C/B is turned ON and if still no power on top two wires replace C/B. If 220 VAC is present on top two wires then press Red Reset Button very hard to make sure it is Reset. Then check for 220 VAC at the Thermostat ( bottom two terminals), if 220 VAC is present then check for 220 VAC on the Heating Element terminals (bottom of picture). If 220 VAC is present on the terminals of Heating Element then H/W Heater should be working otherwise Heating Element is Bad and replacement is necessary. Good Luck! Handy Henry

3a fuse blows stat wiring good


Your heating element could be shorting out inside the tank.If you have 2 elements, disconnect one wire from the top one turn on. if the fuse doesn't blow then the top element is mad.try the same check on the bottom one ,dont forget to put the wire back on the top one first. remove fuse before you disconnect the wires.becarfull

It sounds like upper or lower thermostat.
Thermostats turn off one leg (or one wire) in the 240Volt circuit, so each elements will test for 120V even when thermostat is off.
When thermostat turns ON, it closes circuit by adding the second leg to 240V circuit, and element turns ON.

The next thing you need to do is find out whether you have 240v to the bottom element....the top will not heat till the bottom is satisfied...

The controls of electric water heaters are designed so that at no time are both the top and bottom heating elements energized. Nearly all electric water heaters of this capacity in the US & Canada (other places, too) operate on 240 Volts.

When the water in the tank is below the set point of the thermostat (in your case - 120 degrees), the top heating element is expected to be on - (unless there is an issue with the top thermostat or limit switch). The top most control is the "high temperature limit". It is identified by the reset button on it. Make sure this isn't tripped by depressing the button. If it clicks - it was tripped and should start to make hot water at this point. If not tripped, you should check for the presence of 240 Volts between the heating element terminal screws. Do not measure from ground to a terminal screw and believe 120 Volts is "good". To make heat, you need 240 Volts - not 120 Volts measured across the terminals - not to ground. The amount of heat created running at 120 Volts is only 1/4 of what it will do at the correct voltage.

If you don't measure 240 Volts on the top element, check the bottom element in the same manner described for the top element.

If unable to measure 240 volts on any element, either there is a problem with the power source (blown fuse or circuit breaker), high temp limit switch, or thermostat(s).

If 240 Volts is present on either heating element, and water is not warm / hot in 30 minutes or so, a defective heating element is suspect. You can change controls without draining a tank, but replacing elements will require draining the tank first. Do not power the water heater without first filling it.

You can read a very detailed "how to" article about checking water heaters here.

I hope this helps - and good luck!

Have a new electric tank,top element wont come on,replaced thermostat 3 times top element comes on once but next morning not enough hot water&top element wont come on,can someone help? thanks


The top element only comes on when the heater is about out of water. The water is directed to the bottom of the tank. Cold water stays on bottom, Bottom heater element heats water. If you use all that water then the top of the tank gets cold and the top element comes. When the top of the tank is warm, then the bottom element comes on. I would susupect the bottom element as it does most of the work. If you have an ohm meter, turn off electric, and remove wires from element. Check element for continuity. If you don't get reading, then that element is bad.

Residential water heaters USUALLY follow same diagram unless water heater is wired for other purpose. Multiple diagrams on instructions show available options. Take photo of wiring before removing wires on any electrical device.
Upper element.
Black wire from top of heater connects to #1 top left screw.
Red wire from top connects to #3 top right screw.
Blue wire from upper element connects to #4 middle screw on right side
Red wire from lower element connects to #4 middle screw on right side
Yellow wire from upper element connects to #2 lower left screw
Black wire from lower thermostat connects to #4 lower right screw
Upper element: Yellow and Blue wires connect to either screw
Lower element: Red wire from top connects to either screw
Lower thermostat: Black wire from top connects to top screw
Short wire between lower thermostat and lower element

Wiring


The new thermostat (I assume you must be changing one) will have several possible scenarios. If you have two elements and thermostats you look for the diagram that says two elements working NON-SIMULTANEOUSLY. In other words the top element heats until the thermostat is satisfied and then, and only then the power is sent to the bottom thermostat. The wiring diagram will have the numbers and colors of the wires for everything in the heater except your feed wires. Those colors don't really matter much. You will have three conductors--two hot wires and (likely) a bare ground wire.

Hope this helps.
