Can you trace it back to breaker box? I'm thinking green and yellow are not needed but only way to tell for sure is breaker box. Volt Ohm meter would be helpful also.

I have a new heater with diferant terminals from the old one so not sure how to atach the wires


There is no need to rewire the internal of the heater!
Just bring in the electrical supply to the heater, it can be either 120 or 240 volts.
If the heater you have is like the picture associated with your post, then all then have to do is change the supplied plug from 240 to 120. It comes pre set for 240. That plug is inside the cabinet.

If any other brand, then you need to change the wires at the transformer of the heater. All heaters need to be supplied with primary voltage: 120 or 240. Then the control system is supplied with secondary voltage out of the transformer. The secondary voltage is no more than 28 volts. and these wires are normally colored as blue or yellow.

Secondary power is already wired within the heater. NO need to change where they are. You will only need to deal with the Primary wiring.

There are many varieties of transformers that transform high primary voltage to a low secondary voltage of 28 volts. and these transformers have many wires: primary & secondary.
I will try to make this easy to understand.

If you have a Gas Heater Transformer with these colors:
  • Red
  • Black
  • White
  • Green
Or...
  • Red
  • White with Red Stripe
  • Black
  • White with Black Stripe
  • Green
These are Dual Voltage Transformers, you can bring in either 120 Volts or 240 Volts

If you bring in only 120 Volts...
1st example:
The Red wire will not be used! Hot wire to the Black, and the Neutral/Common, to the white wire. Green to ground.

2nd example:
Connect the Red wire with the White with Red Stripe together and connect these to the incoming Neutral/Common wire, normally White.
Connect the Black Wire with the White with Black Stripe to your incoming Hot Wire, which is normally Black.
Green to ground

If you bring in 240 Volts...
1st example.
1 Hot wire to the Red, the Other Hot wire to the Black, and White wire is not used. Green to ground

2nd Example:
Wire nut the two Striped wires together. then one incoming Hot wire to the Black, the other incoming Hot wire to Red.
Green to ground

Or This is only a Low voltage - 120 Volts Only
  • Black
  • White
  • Green
Or either any of these combinations...
  • 2 Blacks w/Green
  • 2 Reds w/Green
  • 1 Black, 1 Red w/green
This type will only be a high voltage, 240 volts only
Picture below is what a transformer looks like and it is where your incoming supply wires go. The smaller leads with the spade connections will go to a specific location & is the 'Secondary" .

Good Luck

Replace et724-A with new digital timer 15313


You are install GE 15313 timer
Open following link to identify timer
http://waterheatertimer.org/GE-timers-and-manuals.html#15312

15313 timer does not require Neutral wire.
The timer you are replacing has neutral wire (White wire)
So replace timer wires 1:1 except do not connect timer to white neutrals.

Keep in mind the 15313 is for incandescent lights only and is not for CFL or LED lights.
If you want timer for CFL, then install one of the other timers shown on page.

Replaced fan motor for outdoor ac unit old fan has blue,black,red,and green wires new fan has brown,black,yellow,brown/white and green what goes where


Hi, the 2 - brown wires are for there own run capacitor they should have sold you. One of the browns will have a white stripe. The new cap has only 2- terminals and you put a brown on each side. The black and yellow wires are both hot which 1- will go to 120 volts on the load or out side of the contactor, and the same with yellow, 120 volts. This gives you 220 volts to run the motor. Look on the new motor and you will have a diagram or on a paper that comes in the box. The old motor used the dual cap to run the compressor to. The green is just a ground wire. Screw it to any metal part or screw. You should be able to put the black and yellow hot wires where the old black, red, or blue were as long as they are 120 volts which I am sure they are. Get a cheap tester when you go get the cap for the new motor, and check the old blk, red, and blue terminals to ground and you should have 120 volts on at least 2 of them. Put the new yellow to 1 and black to another, browns to the new cap and your off and running. Keep me posted. I do this everyday. Please be kind when rating me, thank you.

Replaced Bryant T-stat model TSTATBBNB001 with Honeywell t-stat


Your original wiring configuration seems to indicate that you have an air conditioner (not heat pump) and either a gas or electric furnace. If this is the case you may need a different thermostat for your application.
