what makes you think there a problem with the blower, Most newer blowers have multi-speeds so be careful to only have two wires hooked up at a time , always have the ground hooked up, usually the white wire and then try black for high speed, make sure fan is secure it may shift. to check low speed connect only the red wire to power and the white wire to gound . depending on motor, other colors would be medium and medium high is so equipped. if motor gets hot after a while check for a capacitor, they have a tendency to get weak, replace with exact same capacitor. let me know why you suspect the blower.

Thermostat Line Voltage How to Install or Replace


You either have a new line voltage thermostat or have to replace your old line voltage thermostat. In either case the process is much the same.

1286363.jpg

  1. Make sure that all power is turned off at the breaker panel. Most heaters that use a line voltage thermostat usually use 240v current so the breaker will either be a double pole breaker or you will need to turn off two single pole breakers to kill all of the power.
  2. Check to see which wires are hooked to the breakers. In most cases it will be the red and black wires, but I have seen many times that the white and black wires were used. Often there is no red available when the white is used.
  3. Take out the two screws that hold the thermostat to the junction box. When you get the thermostat out make a note of which wires go to the heater (load) and which wires are coming from the breakers. (line)
  4. If you have a single pole thermostat installed one of the sets of wires may be wired straight through the box or have the line and load wires connected directly in the box. With a double pole t-stat you will have both sets of wires running through the t-stat.
  5. Remove the old thermostat and wire the new t-stat in the circuit with the load wires hooked to the load or heater and the line wires hooked to the wires coming from the breaker. Make sure to get a very good tight connection as resistance loads will heat up quickly if good contact is not made. This poor connection can and will start fires.
  6. Turn the power on and check the heater for heat output.
  7. Turn the power back off and carefully screw the thermostat to the junction box securely. Then you can reapply the power to the circuit.

Now you are up and running with a new line voltage thermostat installed.

I am wiring a honeywell thermostat model number ct87n if I select fan on the fan runs when out on auto /heat nothing but if I put on auto / cool and adjust the dial to a low setting the hea comes on....


there is it all depends on how many strands of wire are in there, they start at 2 wire and go to i think 8 wire and maybe more.
The wires are as follows:
1. red = power to stat.
2. green = fan control
3. blue or yellow = ac
4. white = heat
w1 = 1st. stage heat
w2 = 2nd. stage heat.
i am on line if you have any questions. wally

Where do i hook up the blue wire coming from my wall to the 6400d unit and i don't have a white wire


Look at the terminal it is connected to on the other end, at the furnace. If it is connected to the C terminal at the furnace connect it to C on the thermostat. If your thermostat is battery powered it may not have a C terminal. If not, insulate the end of the wire with electrical tape and do not use.

Won't come on


If you check power between the white and black wire you should read voltage, if you only read voltage to the black wire and ground, then it is a problem with the wiring going to the furnace. If you do have power coming into the unit, check the line connections to the transformer. If there is voltage present in the line side, the the load side should read 24v, if not then it is a simple transformer swap. Hope this helps.

No heat after installing honeywell thermostat H8110U


hook up the blue wire in the furnace cabinet where the blower section and the other thermostat wires are connected to the furnace. the thermostat you have uses a common wire from the thermostat to the furnace and this needs to be hooked up in the furnace otherwise you will have the problem you are having.

Can't get new thermostat to work


When you have only 2 wires it is set up to run just a heater only. If this is a central heat/air unit, you would have 4, red for Hot, White for heat, green for fan, and yellow for cooling. sometimes they will have a blue wire that's not being used for a spare only.Some times you can use just the heat part of the stat if you connect the Red to r and if the subbas'e says Rc and Rh .If so, try connecting red to red and if it does say Rc and Rh that means red cooling and red heating.Run a jumper wire across the 2 reds along with the red from the wall. Connect white to w.Try programming the heat and see if it fires up. If not, you will have to replace stat with a 2 wire Heating only thermostat. Do not pull any wires up from the transformer as you will burn it out!! Just remember, 2 wires are for a heater only!4 are for heat and cool, and 8 are used for a heat pump.Sometimes the new stats have the red jumper wire in place and all you have to do is hook your red to either end of the jumper, and then white to W. If no RCand RH, get a heat only stat, or it will never work believe me, I know this.Good Luck and let me know if you need more help. Shastalaker7

I am trying to replace a electric baseboard heater that is 220 volts and I am unsure about the wiring. the heater has a red and black wire and there is a white and black wire coming out of the wall.How do...


if ur are replacing the heater and it was originally 220/240 ur wiring should b ok but to b sure trace the line wire back to breaker panel and look at breaker the white and the black should b hooked up to separate breakers if the white is hooked up to a ground bar usually on the inside side of the panel and the black hooked up to breaker ur line is 110/120 and will cause problems when hooked up. if the lines r 220/240 than red can hook up to white and black to black

How do I hook the wires up for a electric baseboard heater


this heater can usually be wired from either side. meaning your wiring can be brought through the wall inside of one side or the other.

the wiring you bring in to this unit needs to be 12g or larger.

it needs to be on a dedicated circuit. that means you cant splice into any other line. it needs to be for your baseboard heaters alone. that is code and wouldnt want to sleep in a house with baseboard heat that didnt have a dedicated circuit.

baseboard heat is most economical to run with 240v units. 120 is going to cost more to run.

you will need a thermostat either built into the unit or a thermostat unit mounted in the wall to run it.

dont mount the thermastat over the heater. I shouldnt have to explain why.

a 240 volt circuit run from your panel on a 20 amp breaker consists of 3 wires, a ground and a black and white.

in a 240v configuration both the black and white are hot and you must wrap some black tape around the white wire where it shows in your breaker panel and at the handy box in which you have installed the thermostat and then where it enters the heater. this re-designates the wire as a hot instaed of nuetral this gives you to black hots.

you hook the white and black wire to the line in side of the thermostat which should be the two red wires.then the two black load out wires of the thermastat run to your heater. hook your ground (green or bare) to the box if its metal and pig tail it to the ground screw on the thermastat, then out of that pigtail to the heater along with the two hot wires.

you will find a bare ground solid copper wire fixed to the inside connect your ground.

you will find two other wires they are both hots you will connect one of your hots to one of them and the other to the remaining.

what it looks like is an element sitting in the housing the housing is the baseboard and you have a hot wire running through a wire way to the other side and connecting to it and one hot stays on the side you brought the wires to.

in other words since you can wire it from either side you have to have a way to get the energy to one side or the other and they supply a way.

as long as this is labled as a 240 unit both wires are hot. take the covers off both ends you will notice the wire traveling from one side to the other. your goal is to have one hot connected at one end of the fillament and the other hot you brought in to the other end. the best way to hook up multiple heatrs is to have branch lines from the thermastat toeach heater, not to daisychain them one to the other becuase you will have voltage drop as a heater is using it before passing the voltage down the line leading to poorly functioning heaters

Not sure hooked up correctly


The black and white wires should both go to the breaker. Not just the black wire. If you hook only the black wire to the breaker then you are only feeding the unit with 110 instead of 220. Both wires need to be hot.
