What color wire is connected to the "Y" terminal on the thermostat.
If the unit you are connecting is a heat pump A/C unit the orange wire is for the heating mode. Normally the "Y" terminal on the thermostat. "R" terminal on the thermostat is the power to the thermostat, "W" terminal is for heating, "Y" is for cooling, and "G" terminal is for fan operation. At the condensing unit for cooling the brown and yellow wires would normally be for the cooling.

SOURCE: Rudd furnace

You have a safety limit switch that is either bad or needs to be manually reset. Some have little buttons between the two wires going to the switch that you can push to reset. If not they are automatic switchs then one is bad. You have to do an ohms test to see if each switch is bad or good.

SOURCE: Need help with wiring thermostat

first do you have a heat pump unit or standard a/c? standard a/c connections at the thermostat go like this red wire to rh-rc which is the 24v power and you don't have to remove the jumper.white goes to w which is the heating wire yellow goes to y which is the cooling wire green goes to g which is the fan wire and blue goes to c which is the common wire. so if your stat has rc- rh ywgc you should be set if the wires on the furnace correspond with the same alpha may be used if u have a heat pump unit otherwise it may just be a spare you cap off and leave behind the subplate.

SOURCE: Carrier Infinity Control Thermostat SYSTXCCUID01-B

Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you

Kenmore side by side freezer not cold and there is frost on back of freezer wall

you have a defrost problem,it's not going into defrost,bad defrost heater,defrost thermostat,timer or board depending on what model you time send the model number,it should be in the fridge section,on the right hand wall up near the ceiling.first thing if it has a timer advance it into defrost by turning it with a screw driver or if it has a board remove the bottom kickplate and look for the tech sheet,it will tell you how to put it into defrost mode or unplug it..remove all the food and shelves and inside back wall of the freezer,with a hair dryer start melting the ice around the heater if it has a glass heater on the bottom ,if you can't get it into defrost you can unplug it,remove the two screws that hold the heater into place and look at it,if it's all black inside the glass change it out,you can check it with a meter to see if it's good but sometimes it will read good but like i say if it's all black change it out,if you have a calrod just a black rod going around the coil most likely this won't be your problem,it will be the thermostat,next you have to check the thermostat,it's on the top of the coil,if you know how to get it into defrost,first unplug it,then cut or unplug the two wires going to the thermostat,bypass the thermostat by wiring the two wires together,plug it back in,put it into defrost and if the heater comes on then you know the thermostat is bad,it's a good idea to change this while you're in there anyway,also if you look at it and the top looks like it's buldging off then water got inside it and it's bad,if you send the model number it would be easier to help you but you get the idea,you have a bad part in the defrost section,if you have another fridge you could just shut it down and it will melt out on it's own,then you can check the heater with a meter,the only thing is the thermostat has to be cold to read it out with a meter,like i said it's a good idea to change it anyway,you can cut or unplug the wires and bypass it and see if the heater comes on,if it does come on leave it on,it will help you melt out the ice or cut the wires,remove the thermostat and put it in the other freezer so you can check it with a meter but the best way is to just bypass it,put it into defrost and see if the heater comes on,if the thermostat and heater are good then you have a bad board or timer. copy and paste,this is not a side by side but the thermostat is in the same place on the coil,just remember where you remove it from if you change it out,it has to go back on the same spot.if you need more help send the model number and we can go from's a little tricky trying to tell you what to do without knowing if there's a board or a timer in it.hope i didn't confuse you and good luck

We have a ge electric water heater - last night we set a new jug of detergent on top of it over the electric plate on the top of the unit - it had a hole ( small leak) in the bottom - it leaked all night...

You flooded water heater wiring compartment with detergent, and the wires were shorting so you turned off power and cleaned detergent. Now water heater doesn't work.

1) The heat from shorting might have tripped ECO reset button.
Open top cover on water heater, and push in red reset ECO button.
Be sure to re-install insulation and cover.

Other steps:
2) Turn off power. Remove wire nuts. Cut off copper ends of wire, and re-strip each wire so fresh copper shows. Make sure no detergent is on the copper. Use new wire nuts and twist very tight against copper wire.
3) Cut back burned ground wire. Remove ground screw and clean thoroughly. And then reattach clean copper to ground screw.
4) Turn power back on.

5) If water heater still does not work, then test across top two screws on upper thermostat for correct voltage.

How do I wire around upper heating element until I can get an other one to replace it?

Question posted under marathon electric water heater.
Marathon is 240Volt dual element non-simultaneous water heater.
Non-simultaneous means that upper part of tank has to reach temperature before power is sent to lower thermostat and element. So if upper element is bad, then water heater has no hot water.

1) You need to by-pass upper element without by-passing upper thermostat.
2) You should never by-pass upper thermostat because it has ECO-reset protection.

3) Open following link for image of wiring:
4) Take photo of your wiring in case color code is different on your specific model

5) Look at upper thermostat.
Remove yellow wire from terminal 2 on upper thermostat, and cap off temporarily.
Remove red wire from terminal 4 on upper thermostat, and move it to terminal 2 on upper thermostat.
6) For more effective operation, look at lower thermostat.
Remove black wire from lower thermostat terminal 1 and move wire to terminal 2 on lower thermostat.

GE TFH24PR refrigerator will not go into defrost mode. I recently had to defrost the freezer coils manually. What is the likely cause and fix? Where are the timer and the circuit board for defrosting...

next time open the door,look at the right hand wall in the fridge section up near the ceiling and you'll see the full model number,the things that can cause this is a bad thermostat,a bad heater,or timer.the timer is in the fridge section up near the light,could be behind the light cover but it's up there,find it and put it into defrost,with a screw driver turn it slowly until it clicks,it will be in defrost,open the freezer door,if the fan isn't running then you have it in defrost,if the heater doesn't come on you have to check the thermostat,the easiest way is to first look at the t-stat,if it has a clear plastic ring around the top and it's pushed up on one side the t-stat is bad and you'll be able to tell just by looking at it,also your going to have to cut the wires on the t-stat if it's bad so you can shut off the freezer control or unplug the machine,cut the wires and bypass the t-stat,turn it back on,if the heater comes on then you know the t-stat is bad,if the heater doesn't come on shut the freezer down again,remove the two phillips screws and pull out the heater,remove the wires,look at the heater,if it's all black change it out and it''s not a bad idea to replace the t-stat too,if the heater isn't all black looking read it out with a meter to see if it's bad,most of the time one of these will be bad more so than the timer or any other problem. just make sure power is coming to the t-stat and the heater and change them out and you'll be all set.good news with the heater kit that goes into your machine is part number WR51X443 and it's around 85 dollars,it's a double heater instead of one,the t-stat comes with it and it has instructions on how to wire the heater in so you get both pieces the t-stat and the double heater.install this and you'll be all set

Hot water runs out in 5 minutes it use to last 20minutes

Electric water heater can be repaired by homeowner.

Water heater has some hot water.
We know 3 things for sure:
- electricity is ok
- upper element is ok
- tank does not have overheating problem

Here are the suspects:
- Burned or loose wire
- Upper thermostat not working
- Lower thermostat not working
- Lower element not working

What to do:
1) Turn off power, open water heater covers and look for signs of burned or loose wire, especially on lower element. Burned wire on lower element says lower element is burned out.

2) Test lower element.
Lower elements burn out when sediment builds up inside tank.

3) If wires are ok. And you do not want to test parts, then replace upper and lower thermostat for 25$. If problem persists, replace lower element.

4) If you want to test thermostats and elements before replacing anything:

5) When finished, be sure to put insulation and covers back on tank so thermostats don't receive cool air and misread tank temperature. This will prevent overheating of tank that causes red reset button to trip.

Pilot is lit but the heater won't fire up

A few things dictate when the main burner turns on. One is a thermocouple not getting hot enough, the other is a bad thermostat ot thermostat wire, and another is the gas valve. First look at the gas valve located on the heater and make sure it is in the On position and not in the Pilot position. Remove your thermostat and jump the two wires together. The heater should light. If not, go back to the gas valve and find the wires up to the thermostat, the should be attached to terminals marked TH and MV or something similar. Jump the terminals. The heater should start. If not, you may need to replace the thermocouple.

Power light comes on but it doesn't run

You need to trace the path of electricity. With it unplugged, remove the cover and look at the wiring from the power light on, Its possible that a wire burnt off, you will be able to see it easily if so. If its an internal short, like inside the thermostat or power switch, then you need a meter to accurately find the problem, or change parts and hope to get lucky.
