Pilot on my gas furnace won't stay lit


Try cleaning the thermocouple tip if you can see ashes or any buildup on it. If you know the wind isn't blowing it out (had mine blow out from high winds before) then I would change the thermocouple before anything else.

Per landlord, need to light pilot


You would smell the gas, so you're probably ok. Lighting the pilot is not too tough, first you have to get the cover off the furnace. Inside you will see pipes and parts. Hopefully on the cover, inside or out, or somewhere inside the furnace will be instructions.
If not, find a knob that has 'pilot', 'off' and 'run' or something like that. It will probably be in 'run'.
Usually, you have to push the knob down and turn it to get it to the 'pilot' spot. When you do, have something to lite the pilot, which will be inside the furnace more, near the burner. The burner looks like a gas stove or oven burner. The pilot place will be at the end of a small tube.
With the button held down, wave something burning around the burner area. especially at what may be the pilot. The pilot doesn't put out much gas, so don't worry about things blowing up.
Once the pilot has lit, hold the button down for a while, at least a minute. Then you should be able to release the button and the pilot should stay on. If it doesn't, you need a serviceman to come. Let the landlord know the pilot would not stay lit.
If the pilot stays lit, move the knob to 'run' or such, and the furnace should lite, if the thermostat is set higher than room temp. If it has been off, and the room is cool, it should lite.
If the furnace doesn't come on, let the landlord know.
Most landlords have service people for this, it was my job for a long time. Lighting pilots was a common chore for me. If you can, have the landlord send one out to show you how to do it.
As you see, it's not all tough, but it's not all easy, either.

How do you lite the pilot lite on a Rheem Gas Furnace Model #rgma-125a


If I recall correctly, model number Rheem furnace you listed has electronic ignition to light the pilot, when the home's thermostat calls for heat. Is this what you're having a problem with?

Blowing cold air is there a pilot to light


No pilot on this model. If the room air blower is constantly running it is telling you that there is an error code stored on the circuit board. Look for a small viewing port in the lower section of the furnace. Look in it for a flashing light. Count the number of blinks. Now remove the front panel and on the reverse side there will be a wiring diagram. Also on the wiring diagram there will be a Diagnostic Chart that will explain the blinks. If you remove the panel that opens the door safety switch, it will cut power to the unit and erase the code so find the viewing port first.

PURGE LIGHT FLASHING


It is a discharge temperature sensor and should be located in the duct after the coil. It should be just before the bypass damper.

My carrier 58sta furncace is blowing cold air constantly


Code 33 is "limit is open or flame switch is open"
FIRST make sure the filter is clean. Turn off unit then turn back on.
if it works but then later gives you a 33 code then you might have a dirty a/c coil (if you have a/c) that will cause the limit to open. 1st try that

The Pilot on my electric furnace will not stay lit, blowing cold air instead of warm. The model is L8T-UH.

Gas furnace is constantly blowing cold air


An indoor blower running when it is not supposed to usually indicates an overheat condition. I would guess that it has been cycling on and off for some time and finally caused the high limit to stick and not auto reset. if you tap it sometimes they reset. the real problem is that it has been overheating from lack of airflow, over sized unit, not enough return air, too many closed registers, dirty filter, dirty squirrel cage blower and or air conditioner a-coil. If you get it started again sit and watch the unit run the flames should come on and stay on for the entire heating cycle, not going on and off.
I wish I could help you more but it is difficult without seeing the problem myself. Good luck! this should get you started!

We have a Janitrol PGB 048125-1 unit and it is not blowing heat. the fan comes on when in fan only mode on thermostat but once we turn it to auto it goes off. we cannot get the unit to blow hot air. does...


If the unit is newer than 10 years I guess there will be no pilot light per sey. You will have to look at it to tell for sure. Here it is supposed to work. When there is a call for heat the thermostat will close and send a signal to the furnace to start the exhaust blower. When the blower gets up to speed, it closes a pressure switch that will send voltage to the gas valve and to the igniter. The igniter glows or sparks lighting the pilot. Once the pilot lights it sends a signal that all is well, then the gas valve opens up more and the burner(s) light. There is a sensor that tells the control board when the flame has stayed lit. Once that is done, after a period of time or as the heat exchanger gets to a specific temperature, it will turn on the room air blower and blow hot air. Once the thermostat has been satisfied, the furnace turns off. Now, get in front of the furnace and with the door panels off (you may need to tape down the door safety switch to make this work) watch the furnace go thru each step I described. Once you see where the problem is, you can start the proceed of repair. There may even be a flashing light indicating a problem. Find the wiring diagram on the furnace and look for a diagnostic chart and compare the number of blinks to this chart.
