Question about Air Conditioners

1 Answer

I have a rheem furnace. A week or so ago, we had a burning smell, and the furnace shut down while I was gone. When I came back, it did start again, but the smell was still there. I called a guy who came over, found some melted wires (dont know if they were in his pocket or not before he came), and the unit worked for about four hours after he left...then there was a new sound..a chirping sound, and then the heater died a couple of days ago...I took the squirel cage apart, took the motor down, and the guy checked it, along with capacitor, and he said the motor was bad. Sold me a new motor, different capacitor (this was a 1/2 horsepower, even though the one that conked out was 3/4, but he said that because my old one had 8 amps on it, he surmized it was probably a 1/2 horse. He said the 1/2 horse was fine) I re-installed the whole thing and I get the intake blower (Or whatever it is, starting, then the red glow of the igniter, then the gas...but the fan never gets going, and the unit shuts down. I checked the wires again..called the guy, as I wanted to make sure the wiring was right. Thought maybe the capacitor might be backwards. He said it cant be backwards...would work either way...no go...any ideas?

    He is right about the capacitor, explain what wires were on the old one and what ones are on the new one?

    Where did you wire the motor to? Circuit board or fan center?

Your control board may have a problem. When the burner fires up, after a time delay of about 45 seconds, you need to use a voltmeter and see if the terminal marked H for heat has 120 volts coming off it. This voltage will be the power to spin the blower. If ther is 120 vac at terminal H then the blower motor or cap. is no good. If there is no 120 vac then you may have a bad control board.

Hello
Its possible the motor is going bad,more likely the blower wheel assmebly needs to be cleaned.

Have a look at the blower motor assembly for dust and dirt on and around the blower motor and wheel.Clean it off with a damp rag and a vacum cleaner.
Check the area for any trash or loose stuff that could be causing this smell.

Usually when a motor goes bad it will run for a while then slow down,then stop on thermal overload.

Then when it cools off it will restart.

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.

Burning smell and icing


Sounds like your blower motor in your furnace or air handler has burned up. shut the unit down and replace the motor. make sure the ice is melted and the unit is dry before you turn it back on.

Overheating and has "hot glue gun" smell


If the furnace is overheating you are smelling the insulation and the adhesive glue burning. Shut the furnace down and find out why it is overheating. Make sure the filters are clean. Check the blower motor and capacitor.
Good luck.....

Carrier Weathermaker 8000 turns off intermittently


You can find what the error code is by looking on the inside of the bloewr panel. If it is still there after all these years there is a code list right around the wiring diagram. If my memory serves me correctly it is a limit problem. But be for sure and check the code sheet.

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.
