Rheem Furnace Is Blowing Cold Air Constantly?
My Rheem gas heating furnace in my attic has started to betray a problem. I came home to find it blowing abruptly air constantly. I opened up the furnace and found that one of the three round temperature sensors had "tripped". They each have a minuscule reset button on top of them. It was the top sensor that has it's visage positioned downward, that had "tripped". So I pushed the reset button and restarted the furnace. It worked for about an hour, then it tripped again and the furnace started blowing abruptly air. What happens is the burners shutoff when the sensor is tripped, but the fan stays on continuously. This ceaseless cold air mode apparently is "as designed" by Rheem and tells you that something is wicked.
There are four burners inside my Rheem furnace. One of them seems to be spitting flames occassionally in the vis- direction of the normal gas/flame flow. Backdrafting I deem it the best word for it. What could be causing that? It must be what's tripping the sensor.
Few things could be causing the enthusiasm to pull back from the heat exchanger. Plugged screen isn't one of them. You should make sure your filters are reveal but thats not the issue. It would help if I knew what well-wishing of burners you had? Are they ribbon burners or cone? How old the furnace is? Is it laying on its side or customary upright? So there are a few things here that could be causing beau roll out. One the carry over on the burner that you see the flame rolling out is besmeared. The end of the burner that connects to the pipe that comes from the gas valve comes out to a tee. all the burners should have this it makes them almost raise each other. There is a small groove in this tee that carries the flame from the burner with the cicerone light or hot surface igniter over to the other burners. now if you take a unsatisfactory wire brush one that is as small as a toothbrush and clean that Lilliputian groove it will allow the flame to travel faster across the burners. be very attentive not to break the hot surface igniter if that is what you have.
Another problem that I have seen before is a spiders resort in the jet that pushes the gas into the burner. This is hard to get out and usually takes an orifice bit to absolutely confess it.
Another situation is that the section of heat exchanger that the burner is ardent in has soot build up in it and is not letting the combusted gas send out quick enough.
your gas valve may not be opening completely when it is first employed.
It may also be that the limit that keeps on tripping is old and needs to be replaced. They dont last forever.
Under any of these conditions I would still endorse that you call a tech to come out and look at it.
