DGAT070BDD--Won't heat up. Won't shut off.
Posted: Fri Dec 28, 2012 1:23 am
We bought and moved into our trailer in July of 2011. We had no problems last year for heat. The furnace worked wonderfully. We have A/C hooked up as well, and the A/C worked well throughout the summer. Now, we have been trying for a couple of months to get heat to work properly. When you turn it on, you hear the ignitor, then the flame lights. After a few moments, you hear the blower kick in. However, when the air comes out of any of the vents, it is just barely lukewarm. It's warmed than outside, but not 72*, which is what the thermostat is set at. We have tried our own troubleshooting at home, but have come across no explanation or solution. We checked the c-coils, which I was told to do. They were covered in dog hair, probably from the previous tenants, and we cleaned it all out. We also have looked at all of the wire connections, thinking maybe something isn't connected that should be. Nothing. We changed the thermostat las night as an almost last resort. We upgraded to a programmable, digital thermostat that I assume is okay to use. It hooked up properly, and turns the furnace on and off. We still don't have heat. The thermostat has been set at about 72* for the past 2 weeks or so, and it is still only heating to about 60-65*. After hooking up the new thermostat last night, we shut the heat off completely for about half an hour. The temp actually rose to about 64* on its own without any heat source. When we turned the furnace back on, we heard the ignitor switch, and then saw the flame. It was burning blue, and even. Then, the blower kicked in. We were hoping the air would warm back up in a moment or two. That did not happen. It was still blowing the coolish air, just barely lukewarm. It has been in the teens during the day where I live, and in single digits or below at night. I know that 60-65* is not cold, but it is far too chilly to sit in a t-shirt for me, and I'm an adult. We have two very small children, and it is far too cold for them. Their room is furthest from the furnace, and they wake up in the night cold. I don't feel like it would be safe to put a space heater in there or I would. We do have one set up in the living room during the daytime, but it is shut off when we are not awake to supervise it.
Any advice/sugggestions would be greatly appreciated. Thank you in advance for any suggestions.
Note: I am a beginner, so using basic language or explaining things would be helpful to me.
