    Hi Anonymous How old is this unit? Is this a USA made product? Are parts still made for it, have you checked?

SOURCE: CD won't eject. I've restarted and tried all the fixes recommended by MAC forums and so far no luck. Any other ideas?

If it is just the computer that isn't ejecting the disk (and not a physically "stuck" DVD) there is a way to force eject.

Go to Apple menu > Restart and hold down your mouse button until the disk ejects.

Or you can try the firmware method...

If all other methods fail, you can try to eject the disk using the firmware (this may not work on all computers). To use this method, start up and briefly use the computer with only the firmware loaded, not the standard Mac OS X interface.

To eject a disc using firmware:
Restart the computer.
When you hear the startup sound, press and hold the Command-Option-O-F keys. (The Command key has an Apple on it.)
Release the keys when you see a white welcome screen.
At the prompt, type:
eject cd

Press Return, then wait a few seconds. The disc drive should eject the disc, and "ok" appears on the screen when the action is complete.
Type:
mac-boot

Press Return.

Your computer starts up normally and you see the familiar Mac OS X desktop.

THIS IS A COMMON PROBLEM WITH THE DOOR SWITCHES, MY FIRST ANSWER WOULD BE REPLACE THE SWITCH SECOND WOULD BE OPEN THE DOOR AND PUSH THE BUTTON IN AND SEE IF THE FURNACE WILL WORK. THIS SWITCH IS JUST A DOOR SAFTEY IF THIS WORKS. I HAVE TAPED A PIECE ON THE INSIDE OF THE DOOR WHERE THE SWITCH WILL HIT THE DOOR ABOUT A 1/4 INCH THICK AND SEE IF THIS WILL GET YOU RUNNING UNTILL YOU CAN GET A SWITCH

SOURCE: I installed my honeywell rth221b1000 this summer

If when you turn the heat on you hear the furnace fan start up (exhaust fan) then the problem is NOT the Thermostat....need some more info on the furnace...the Wiring in the thermostat should include a Jumper wire between RH & RC if you have 4 wires and no jumper required if you have 5 wires

We have royal red furnace to heat our home.The fan dose not stop.


Details.......does the furnace function normally otherwise? Might just be a stuck fan switch. Make sure the thermostat hasn't been set on Fan ON setting or summer air circ. on older furnaces.
Find the fan switch and tap it and see if fan quits. If it does,fan switch is bad.probably. Always make sure your air circ. filter(return air to furnace) is replaced every 3 mo. or so,too. don-ohio (:^)

Where is the summer/winter switch located on Dayton Fuel Trimmer furnace model 3E438A.?


The typical 'summer/winter' switch is an added switch associated with OLD heating systems back in the 50's and 60's before central air conditioning became common in homes. I doubt that your new furnace had one installed because you can accomplish the same thing by switching the fan on at the thermostat sub-base. That is, of course, providing you have a subbase with 'fan-on-auto' on it.

My furnace is an older type furnace and it was working fine yesterday but the blower won't shut off after it runs for a while it run continueally I was wondering what I could do to fix this pr


When you say 'older furnace' I am assuming old enough to where there is no circuit board. They will usually have a thermally activated 'fan-limit' switch with a bi-metal sensing device. Most older furnaces had either a Honeywell or a White-Rodgers controller and they look almost identical. With the furnace door off, look towards the top of the furnace vestibule (above the flame area) for a rectangular box approximately 3 1/2" wide by 5" long. Tap the side of the box with a screwdriver and if the thermostat setpoint has been satisfied and the gas burners have been off for more than three minutes, the fan should then shut off. The switch contacts are either stuck together OR the bimetal sensing device is weakening from thousands of cycles.

If it continues to run, squeeze the sides of the 'lid' of the box and remove the cover. Inside you'll see a round moveable dial with three pointers, marked 'fan off, fan on, and limit'. The 'limit' should remain at or near the 200 degree setting, the 'fan on' can be anywhere around 140 and the 'fan off' can be anywhere near 100 degrees. It is the 'fan off' position thats giving you the grief.

Turn the thermostat up again and sit there and watch the dial do its thing and yo'll understand better how this control works. Watch it rotate past the 'fan on' setting and observe the fan turn on. Turn the thermostat below room temperature and watch the gas shut off and the dial rotate back towards the 'fan off' setting. If it hangs up again before twisting past the setpoint, you can slightly increase the setting to compensate for the weakening bi-metal element. But just a tiny bit, not a great amount or you will have the fan shutting off with a lot of residual heat still in the heat exchanger. The idea of the delay in shutting off the fan is to remove all that residual heat and transfer it to the house.

There are other brands that utilized 'timed on' fan controls, and there are a few other variances of controllers but what's described above should cover the vast majority of older furnaces.

Remember there is ELECTRICITY inside the fan control and any adjustments should be done with the power OFF !!!!

if it is shutting off abruptly the limit is either wired wrong or set wrong. If the fan comes on and blows the flame out there is a hole in your heat exchanger which can result in fire or carbon monoxide poisoning. Have an experienced tech take a look at it to be safe.

Why heater coils glow?


It sounds like you're describing one of two things. The hot surface ignitor in a gas-fired furnace, or the resistive heat strips in an electric furnace.

The hot surface ignitor in a gas-fired furnace lights the burners. This ignitor in modern furnaces serves the same purpose as the standing pilot flame did in older furnaces. It provides the required heat to ignite the gas at the burners. Without an ignition source, a gas-fired furnace cannot provide heat. When the ignitor is activated it will glow bright orange or yellow.

The resistive heat strips in an electric furnace actually provide the heat to a home or building. When the furnace turns on, the heat strips are activated and usually glow orange when they reach peak temperature. In almost all cases, the heat strips are not easily seen or accessed without removing covers or panels inside the furnace.
