Question about Heating & Cooling

Rheem Model# RGDJ-10eamer sometimes lights and sometimes does not

Okay this Furnace is about 10 years old and I already tried to sand the Flame sensor here is what is going on.

Sometimes it works fine. (SITUATION 1)
1. Thermostat tells heater its cold
2. Heater fan turns on.
3. Ignition turns bright red
4. Furnace lights
5. House is warm and everyone is happy.

But after a few days it does this. (SITUATION 2)
1. Thermostat tells heater its cold
2. Heater fan turns on.
3. Ignition DOES NOT TURN BRIGHT RED
4. Fan Turns Off
5. House is cold and everyone is angry.

So, I turn off the main electrical switch try to find a loose wire or clean some pieces or change the thermostat and then we are back to SITUATION 1. A few days or weeks pass and we are back to (SITUATION 2).

Does anyone know whats going on?

    I did take that tube off and blew air in it. It seemed dry. How can I check for good vacuum? When the fan is running would it be okay to take the tube off the switch and place my finger on the rubber tube to see if it's sucking air? Is the inducer the fan part where the tube goes? If so, how do you clean the inducer - or can you?

Find the small tube that runs from the inducer blower. Disconnect the hose and see if there is water in it. If so then I suggest remounting the pressure switch that it is attached to a little higher and so that there is no droop in the tube for water to collect. Just shortening the tube will only allaow water in to the pressure switch. The second thing is with the tube disconnected at the inducer take a straightened paper clip and poke it in the orifice on the nipple attached to the inducer. there may be a partial blockage. Let me know what you find.

Thermal couplet lights up blue flame shoots out. then clicks off.1996 amana 90.


The thermocouple needs replaced. Most are available from a big box hardware store for around $10. They sometimes go bad but still look okay. I keep a spare for my furnace and my water heater. It's a 10 minute job, using simple, common hand tools.

Furnace starts flame come on 3sec then goes out it doe,s this 10 times then starts and runs but air feels cold coming out warm not hot like before


Sounds like you could have 1 of 2 problems:

1. The flame sensor is dirty. The flame sensor is a small rod just a little bigger around than a pencil lead. It is located in the burner section just a few inches left or right from your glow ignitor. The flame will surround this sensor, but it the sensor is dirty, it cannot sense the heat of the flame. Take the sensor out of the furnace. It generally has one screw holding it, and one wire connected to it. Use emory cloth or light sand paper, or even a small wire brush to clean the sensor. DON'T GET IT WET.

2. You may have air in the gas line. This happens especially if the gas has been turned off to the house. You can bleed the gas line by loosening the gas line connected to the furnace. (furnace turned off) Bleed it just for 10 seconds or so, tighten the gas line, check for leaks with soapy water, and try the furnace again. You may have to do this more than once.

I have a goodman propane furnace, model # GMPN080-4 that lights for about five seconds and then cuts off. It does this three times and then stops all together. Tried lightly sanding the flame sensor and it...


The goodman furnace will try and light three time before it faults out for safety reasons. Adjust the flame sensor so that it is closer to the flame or actually in the pilot flame. If the flame sensor is inside the pilot flame and still does not stay lit, your flame sensor is probably defective and should be replaced. You can get one at Ferguson's counter sales.

The furnace will light up and the fan will blow but the flames cut out before my house reaches temp. i have the thermostat set at 70 and the house will not get above 55. i have tried turning the propane...


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.

Hello, I have a Amana Air Command 80 model #GHI90A50, 22 years old. This furnace is on its third ingnition module (last one two yeras ago). The symptom I am trying to diagnose has been ongioing since this...


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.

Rheem 3204-80D furance. Turns on and fan starts. Then in about a minute the fan shuts off.


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. 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.

I have a Rheem Gas Furnace with an old analog thermostat (Wires conneected to terminals R and 4 for the thermostat). I went to install a Rheem digital and programmable thermostat and it indicated that it...


if you have 2 wire at thermostat Terminals at furnace that the thermostat wire attach to should be R & W if your new thermostat has R & W terminals is should work, an easy thing to remember is the red wire on R the white wire on W. If 4 wire at thermostat at furnace green on G, Blue on Y, red on R,and white on W same at thermostat If these do not match find a thermostat with these terminals

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.

Do you have the code reference on your furnace door? If so what does it say? The furnace has locked itself out, and we need to determine what in the world it needs..
