I have a Coleman furnace in my mobile home, P/N DGAH077BBSB, which was installed April 2007. The pressure switch died in March 2010 and I replaced the pressure switch in April 2010 with P/N 9371DO-HS-0031, which is a 0.18 aperture switch (replaced the 0.15 switch in there previously) but did not use the furnace at all after replacement as the weather was warm by then. Fast forward to October 2010, I changed the filters and turned up the thermostat for the first time this season and it only blo

Last week my furnace went out. My landlord called a furnace technican and he said that the limit switch was fried. So he replaced the limit switch and did a tune up of the furnace. It took 2 days for the furnace to finally work properly, and now it's out again. It keeps flashing 33, so I manually reset it and its not working. I unclogged and opened all of the vents, and replaced the air filter and it still doesn't seem to want to work. What do I do?
Hello, a limit switch will open when the furnace overheats due to restricted airflow, check the blower wheel make sure it is clean and also make sure the blower motor is running at good speed and not dragging. Sometimes a weak capacitor can slow dow ... Air Conditioners
I replaced my filter on my Coleman Mach 2006 year model with a reusable 7x16 and it is frezzing up. The original filter was a 16x16 and appeared to be much thinner. I replaced it with 7x16 because that was all that was available and that is about the size of the return air inlet. The problem is my ac lines now begin to freeze if it doesnt cycle quick enough. Could the air filter be the problem? Is it to thick?
Your new filter is restricting the air flow to much go back to the origanal filter ... Coleman Mach 15 Air Conditioner
I am replacing the blower motor in my Coleman electric furnace. The original motor is a Westinghouse 230 volt single phase, single speed motor with a black and an orange lead. Both of these leads connect to "line". There is also a green ground lead that goes from the motor frame to ground. The Coleman number on the motor is 3400-313. I replaced the original motor with an AO Smith motor number 1468-120P. It is a two speed motor with four leads, and, of course, the green ground lead. The leads a

Carrier furnace I have been having an enormous amount of dust in the last 8 months and wonder if it could be my furnace. I have replaced the filters to the returns monthly and have purchased an air filter and checked my drier vent but no solutions so far. .
Furnaces do not generate dust. Dust comes from air born polluters, such as near by construction, heavy flow of people, or seasonal. If this problem persists you can check into an air purifier. I am an Ecoquest dealer and can ... Carrier XHB123D X/Y Series Heat/Cool Air Conditioner

I have a Coleman Presidential 7670 furnace in a mobile home. customer said it came on a couple of times by itself. I ran new wire, fan won,t shut off. Replaced fan switch, fan still won't shut off. Replaced t-stat, same problem. This is an older unit and has no board it has a fan switch a low limit switch, i,m guessing the other is a high limit and a fan relay. I have no schematic and am very frustrated can anyone help me please. Thanks. Brian from california
Brian, it sounds as if possibly the fan relay is stuck however, if the fan will not shut off I would suggest the following, Follow the wires from the fan to the relay on the relay disconnect the fan wire there and see if the fan shuts down if so t ... Air Conditioners

The repairman said there was excessive rust and the area was pitted near the heat exchanger. The furnace is a Coleman EVCON Model BGD12520 about 11 years old. Could this be residue from the burner or something else the repairman saw with his extension light? He said the furnace would have to be replaced and he wouldn't turn it on because of the danger.
If he said there is rusted heat exchanger he was right not to start the unit . you can only call for a second opinion and have a nother repairman confure the heat exchanger is beyond its life. and then ask if there is replacement exchanger avalable f ... Air Conditioners
Mobile home coleman - evcon furnace model EB23B vandalized. I think what is called the Evaporator coil?? (Copper A shape) was taken from the home. All that remains is the blower. Now...was the copper coil for a/c or heat? and isn't there supposed to be some additional heating element that also goes with this furnace used for auxiliary heating that I must replace? I would appreciate any advice as to the parts I must get and possible cost...Thank You.

We have had a coleman central air system for 5 yrs. It stopped blowing cold air into the house about a week ago. You can still here it running but no air is coming out. my husband replaced the fuses and over night it did the same thing so when my husband went to check out the unit outside he said that the line had ice on it. Is there a filter within the central air unit that needs replaced?
Ice is an indication that the refrigerant is not flashing off correctly in the evaporator coil. In most cases you can simply turn the unit off (until it completely thaws inside and out) and replace the filter. Make sure that all the vents in the hous ... Coleman Air Conditioners

My coleman Evcon model DGATO70BDC 1994 starts up and then locks out. The pilot lights and then furnace runs for maybe 2-5 minutes and all that is still running is the air chamber fan. I am thinking of just replacing all parts that could be responsible the problem. There's not much there as probably you know. There is no circuit board just basic electronic ignition,relays thermo senors and etc.. Any help would greatly be appreciated. James
Does your furnace have an air flow sensor? Blowing out the lowest tube will sometimes clear it and allow your furnace to operate. Lack of differential pressure across the burner will cause a lockout. ... Air Conditioners
