Question about Heating & Cooling

Open Question

I have a Coleman 3500-818 furnace. I would like to install a switch so I could manually turn on the fan only for circulating air throughout the house. It's only a 2 wire thermostat so routing through that might not be possible without swapping out the wire and I'm not sure that would be feasable. I'm thinking just a toggle switch mounted to the outside of the furance itself. There are 3 wires that have twist caps that are not connected to anything. - 1 white, 1 yellow and one black. Not sure what they do. Any help would be greatly appreciated.

Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
R- red
AUX-white
Y- yellow
B- O/B
C- black
G- green
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
170-7
190-1
200-0
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters

Motor1258,
Thanks for the response, to be more specific, the nine pin connector was damaged, but I was able to connect the wires back to main unit panel. I am ready to hook to the hunter thermostat and do not know which wires to connect to. This is my problem and I do not want to short something out. Hope this helps, I want to get it installed again. Thanks again for caring....Jerry

First, let me say that if you're not entirely comfortable doing high voltage electrical work, you might want to call an electrician. It's not impossible for you to get hurt or killed or burn down your house. At least be sure to turn of the circuit breaker while you're working on it.

The blacks and whites twisted together are passing through power to other parts of your premises and are always on, so be sure to keep them twisted together. The red is the one that will take power from your light switch and send it to your light fixture.

At the fixture, connect the white to white and red to black, the same as before. At the light switch, connect the black to one side of the switch and the red to the other. When you turn on the switch, it will permit power from the black to travel down the red to the fixture, and from the fixture, the circuit will be completed through the white.

Good luck!

Coleman Evcon furnace. Can i make it circulate air?


Your thermostat should have a "continuous blower" setting. Use that instead of fooling around with the A/C setting

  • Hey, nofarmark91


    Turn the Coleman furnace system switch to the "Off" position on the electric service panel.

  • Locate the manual reset switch near the left side of your furnace blower. Your Coleman furnace has an upper limit switch for manual reset and a lower limit switch for automatic reset.

  • Press the reset button, which you will find in the middle of the limit switch. Use this manual reset button when the furnace burner will not operate. (See Reference 1 pg 4 "The Furnace Controls and their Function/Important" & Reference 4 # 3)

  • Turn the system switch to the "On" position.

  • Good Luck

    I have a Nordyne/Intertherm electric furnace #E2EH-012 in a mfg home I just moved into. The Handy Man removed a 16 x 20 x 1 filter (very dirty) from "somewhere". I'm not sure where a replacement filter...


    The filter will go in to the backside (inside) of the cover with fins in it. There is a 1" (approx) bend (lip) there to hold filter in against backside of cover, in front of air vents. You may have to bend it slightly to get it in there but it will eventually fit in there snug. Incoming air will then be filtered as it is drawn through that filter, into blower area.
    As far as fan switch goes, "auto mode" will be used when furnace is on, and fan will come on & off as necessary to dissipate heat as required. "Ventilate", should be basically same as "On", where the fan comes on to circulate the air throughout the home, just for airflow, and you control it manually.
    So, when using furnace, have fan in "auto Mode".

    Coleman furnace -- fan runs, ingniter won't light,


    Hi,
    The chances are that the furnace was running when the power went out. This will cause the high limit switch to cutout and needs to be manually reset.
    You will find that switch in the blower compartment near the blower. Usually somewher near the highest point of the cabinet.
    Push the little red button firmly till it clicks.
    When the power goes out while the furnace is running the heat builds up because the blower shuts down immediately and causes this limit switch to cut out.
    If you have a electric tester you can also follow the low voltage circuit till you find the open switch. Ther is usually a wiring schematic on the door cover of most furnaces.

    I hope that this will help you to solve your problem!

    Thanks for using Fixya!!

    Draft fan keeps on running after furnace shuts


    That sounds pretty normal for most furnace/heater products. They run the heating element with fan for a cycle then after the heater reaches temperature it will shut off and the fan will continue to run to cool the element and to circulate the heat that it produced. If you want the manual for this product it looks like you can get it here: http://homeappliance.manualsonline.com/ex/product/headline/m/Coleman%2BEvcon/d/furnace/p/DGATO75BDC

    Fan keeps running.


    Some programmable thermostats have a circulate feature. This feature will allow your fan to run approx. 20 minutes per hour. This will insure better circulation, a better balanced temperature throughout the home & better air quality do to more air filtration. Read your thermostat manual to see if your thermostat has this feature and how to turn it off if needed. Another possibility would be on an older furnace with a fan limit control. If the temperature settings are set to low on the fan limit (or if the control is malfunctioning) you could experience a fan that runs a lot even if the thermostat is off.

    Furnace blower not working how it should


    first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

    Is EDF5 required to have intermitant running of Fantech HR 2005R?


    The SHR2005R will turn on the furnace Blower if the furnace is not running to circulate the fresh air. The reason the furnace will not trun on the HRV is, the purpose of the HRV is continuous Ventilation in your home. It should not be turned off when your furnace is not running. That why Fantech has not design the HRV's to run that way. I hope this helps.

    Coleman evcon dgat090bdd. New ignitor won't heat up.


    Looks like 4 flashes might be high limit fault on this furnace. (I don't have a manual for this furnace, just searched online for the code meaning) Is the unit running flame at all? Is the unit running flame for a while then shutting flame off before desired temp is reached? Does the main air fan turn on to circulate air through your diffusers? Does it feel like the unit has much air flow out of the diffusers if the fan is running? Is your air filter clean? If it is infact your high limit switch, it is usually caused by not having enough airflow through the furnace and overheating occurs.

    Hope this helped, let me know if I can assist you further :)
