Question about Heating & Cooling

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.

Burning laptop smell Asus x53e


The cooling fan is attached to a heat sync over the CPU. When dirt or dust collect, the fan tends to slow down and the heating becomes intense. Sooner or later, the CPU will shut down and the system will die. Clean with a can of air to remove the debvris.

Rheem Highboy Oil Furnace runs, then shuts down. I throw in a lit paper to burn off oil residual from failed start. Hit 'Reset' button and furnace starts up. It may start up by itself for the next 3...


Oil furnaces have certain items that routinely go bad or need adjusted to work properly.Some of the common things are nozzle, then gap and location of the igniter,then last is the fire eye. You can see all of these items by pulling the burner tray out. The nozzle delivers the fuel in two ways more or less, first is spray angle then second is the rate or GPH. Nozzles are to spray an atomized mist this means no heavy droplets of fuel. If you have large drops of oil chances are a new nozzle can help you out, please pay attention to spray angle and GPH. The igniter is next, after time they will wear and you can clean the rods and reset the gap to specified distance, that being said it also needs to be a certain distance from the atomized fuel to ignite properly all very important. Then last is the fire eye it tells the furnace that a flame is established and to deliver fuel or flame out and shuts fuel down. These will build carbon deposits at times so simply clean off the deposit and clean the lens with a soft cloth and windex reposition put the burner tray back in hook up the fuel line and off you go.

I plugged mu T30 KU-2367 in power outlet, cam on


Hi,

I'm sorry but by what you have explained you will need to take this machine to a pc repair store and have the AC/DC adaper on the laptop itself checked out just in case it has burned out. Also you have to have the power supply itself checked just in case feed back has damaged that too.

If you feel like doing this yourself you will need a mulimeter to test the voltage coming from the power supply and the adapter on the laptop motherboard.

Also, if this has just happened then leave the unit to cool down and try again as if the cooling fan has seized then the laptop will automatically shut down when it reaches critical temperature.


Plesae post back if you need anymore advice.


Good luck.

Heater Wont light


If it has been off for a while you probally just have to bleed the gas line out. Shut off the gas valve at the heater and then open the union at the heater. Turn the gas back on till you can smell gas. Shut it down and close the union then turn the gas back on and try it again.

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.
