Question about Air Conditioners

1 Answer

I am working on an older reehm furnace a corsaire.

I replaced the main control board. the control light stays green. the yellow dose not light up. the burners come on as they should but the whole thing shuts down after about 15 seconds. I have all the right voltage in the right places and all the safty controls check out to be good. the two fan motors run also. the ignighters are both in good shape and glow. I cant figure out why it wont stay lit. Have I overlooked somthing? any Ideas?

Rheem furnace ,2nd green light blinks 5 times then pauses. I have only 1 furnace,not a twin


5 flashes is a "neutral polarity failure".
on the motor:
White is the neutral and must be plugged in to one of the 3 neutral slots on the control board (usually on the left side of the board)
The other 4 wires (black, red, yellow, brown) are power to the motor and should be connected to the appropriate pins on the control board.

First, for those of you who might not know, "What is a flame sensor?" A flame sensor is a safety device. When your furnace's main burners ignite (light Up) the flame sensor picks up the heat from the furnace's main burning and says, "YES," and sends a signal back to the main furnace control board saying that it is OK to let the main burner stay on. Or if the main burners do not ignite, the flame sensor does not pick up the heat and says, "NO" to the main control board, Shut That Gas Valve and Main Burners Down! Thank God we have safety controls like the flame sensor. Most of the time, after turning your furnace's power off, you may clean the flame sensors with light sand cloth, emery cloth or steel wool. Reinstall the flame sensor and you are back in business! Over the years flame sensors can build up a light coating of burned-in dust and dirt. This insulates the flame sensor so that it doesn't sense the heat of the flame well enough, so by cleaning it you have almost restored it to its new condition. Seldom, but sometimes they do go out completely.

If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

the normal wiring for stats is white=w=heat,red=r=24volts,green=g=fan,blue=c=common,yellow=y=cooling.

This should be doable: First get pen and paper-start at the furnace, theres a group of 5-8 wires leaving the furnace anfd going to the thermostat and a group of 2-3 going to the condenser outside that all need to be identified and the location in the furnace recorded if your furnace has a control board simply right the letter and the corresponding wire color:and whether it belongs to the condenser grp or the T-stat grp.

Furnace
R-red-to t-stat
C-yellow to cond
Y-red to cond and yellow to t-stat
G- green-to t-stat
W- white- to t-stat

If you dont have a circuit board youll be doing the same thing but using the components rather than letters;

Transformer 24v- red to t-stat
transformer 24v com -yellow to cond
Red from cond connected to yellow from t-stat
fan relay - green to t-stat
gas valve - white to t-stat

K then go to you t-stat and simply connect the corasponding component or leter to the thermostat gterminal

Cond Furnace Thermostat

yellow com- blue -C or B
gas valve or w-white -W
fan relay or g -green -G
trans 24v or R -red - R
red connection to cond or Y on board -Y
Hope this helps.

Carrier Infinity Control Thermostat SYSTXCCUID01-B


Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you
