    Merry Christmas - I really appreciate giving me assistance over the holidays. The hose is still in great conditions. What I did is to remove the hose and blow & **** into the switch, closed the burner door and it ignited. I am not sure if this will come up again, but at least during my test, the furnace ignited. I will see again tonight if it comes on again.

    Thanks again!

What you need to do is take and inspect the hose that goes to the pressure switch and make sure that it is not dry rotted. if it is and the combustion blower is running then firsat try to cut the hose down and slip on a better piece of rubber. If not then replace the hose,

I have a rheem criterion ii plus 2 lxe, the blower fan will not run


Check for a low voltage relay that may be used to power the blower, see if operates. To check a blower motor directly, connect it directly to 120volts. (it might be a 3 speed blower with 4 wires connecting it, so check the wiring diagram)

I have a rheem criterion ii a/c and furnace. The power source from the a/c outside unit is not hooked up inside. Where on the unit indoors does the wire attach.


two wires go from the inside unit to the outside unit. Y terminal and C terminal (both low voltage). Power should come from circuit breaker panel (20 or 30 amp double breaker).

Gas furnace, main burner ignites the other 2 don't. then shutdn.


Between the burners is a small rail in the pressed steel where the flame runs across to light the other burners and it sounds like there is dirt or debris in the step over rails causing the problem. You will need to use some compressed air on those rails to clear them out. Once the rails are clear the other two burners should ignite right away.

My rheem quiet 80 ignition flame keep going out. it'll turn on and then go out.


I have a Rheem Classic 80 furnace that would ignite but not stay lit. Cleaned the ignition sensor which was easy to get to and the flame sensor which was under the burner plate and it fired up and stayed lit. The flame sensor was about 6" under the burner plate. Easy to get out, but tough to get back in. Used the old piece of paper shim trick to get the screw to "stick" in the socket and it was much easier to position the screw and get it back where it belonged.

(HVAC) Furnace Not Igniting Quickly


Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.
