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.

Rheem corsair. Just replaced control board and now igniter come on , burner lights but doesn't stay lit. Took out flame sensor and sanded and replaced. Still same issue . Is the sensor bad or can i


If the sensor does not I.D. a pilot, the furnace would not fire, so your OK to this point. The sensor needs to stay in a flame constantly once the main burners light. Sometimes the draft will cause the flame to waver and cause a shutdown. Also, if the blower fan does not start on time, the furnace will shut down. I would check for wavering first.

This is caused by debree in the injector tube or the injector tube is bad. You should see a flame all the way across the injects that is small and runs along the edge. This is where the flame can travel and light the other injectors. If it only lights one or two then try taking the one next in line out and using an air compressor and blowing it out and ensuring that there isn't any rust build up in it. If there is, I would repeat this process for each of the injectors.

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.

There are a few things it could be like the ignitor or the flame sensor is where I would start if the burners ignite then the ignitor is okay if they lite and then turn back off then the problem could be the flame sensor. The flame sensor you can take the flame sensor out and clean it with a piece of sand paper or emery cloth and it should sustain flame.

Sounds like it could be a dirty or bad flame sensor.
When the burner lights ,there is a flame sensor in the flame and it is suppose to sense the flame and send a signal back to the control board which will keep the gas valve open, if it gets dirty or is bad it doesn't send the signal back to the board and the board will shut the gas valve off and after three tries it will lock out the furnace and you have to reset it to get it to work again.
The flame sensor looks like a wire and it's in the flame usually it will get gas deposits on it, then it won't work.
You can clean this sensor with an extra fine piece of steel wool, but before you attempt to do this DISCONNECT ALL POWER TO THE FURNACE.

Rheem criterion II flame stays lit for a few seconds then only cold air blows through the house


Your furnace needs a tune-up. MODERN FURNACES REQUIRE REGULAR MAINTENANCE!

My furnace works intermittently.


You may have a dirty flame sensor. There are a number of other possible causes as well. Rheem/Ruud/Weatherking furnaces also have problems with the connection on the blower deck.
The flame sensor sometimes must be bypassed around the MOLEX CONNECTOR in the deck due to humidity.
Hope this helps.

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.

clean your heat/flame sensor with sand paper or steal wool. If the sensor is dirty, it won't detect the heat from the flame and it shuts the gas off. Clean the soot and junk off the sensor and it should work fine. I have to clean mine every year. After spending hundreds of $$ every yr on tech calls..I figured out the problem and in 30 sec I'm up and running again.
