The glow thing lights but why not the gas oven?


Lol...the glow thing? Heh, its called a glow bar--I need the make/model number to help you more accurately--how old is the unit? If the glow bar is worn out, a classic symptom is that the center glows but not the rest of the heat material--when operating correctly, it's so bright you almost can't look at it. To troubleshoot one accurately, you will need a voltage/ohm clamp-on meter for reading amperage. NORMALLY, a working glow bar uses approx 4 amps of current, the gas valve senses this current draw and opens, letting in gas for ignition. You will have to have access to the wires going to the bar. Set the meter for amps and clamp it around one of the wires. Turn on the oven and check the current draw. If you are hesitant about doing any of this, call for service! The problem could also be a defective gas valve, broken wire, loose connection. If your stove has some years on it, and the glow bar has never been replaced, I'd start there--most of the glow bars I've encountered are somewhere around 100.00 give or take. THEY ARE DELICATE. Don't drop it, hit it, or touch the resistive glow bar material--it will break in a heartbeat(ask me how I know this!) I hope I helped you!

E250 drivers


First, check the input volume for your microphone. Right-click on the speaker icon in the notifications bar (or open the audio control panel) and select Recording Devices. Select the microphone in the list by clicking once. Then click on Properties in the lower-right. Under the Levels tab, you will see the sliders that control the input volume. Make sure they are turned up.

Also, check the input volume on your mic or the switch.

Here is the download page for drivers (these are the same drivers even though the e250 is not listed.

After ten minutes the dryer stops and the filter light is lit


The glow-bar system sends electric current through a heating type of element until it glows hot enough to light the gas (this is used on most older style dryers) An I.R. sensor (infrared sensor) determines when the glow-bar is hot enough to light the gas, it then sends a signal to the gas valve to turn on.

To test this system, open the front cover where the burners are; start the dryer in the heat cycle; you should see the glow bar getting red hot (the glow-bar sits inside the burner box just above the burner tubes - there are two types; a round one that has spirals, and a flat one that looks like half of a coat hanger except smaller. If you have a hard time identifying them go look at the pictures of them in the store section) If nothing glows you will need to take a voltage reading across the glow-bar leads (there are 2) as you first start the dryer. No voltage means it's something else. Voltage means replace the bar (a replacement glow-bar should be kept in stock).

If the glow-bar lights and does not go off then the I.R. Sensor has failed. (I usually replace the glow-bar along with the I.R. sensor because one will take the other out, and it's just good maint. procedure to do as such.)

If the glow-bar lights for about a minute then goes off and you do not hear a click sound come from the gas valve (this click sound is the coil in the gas valve opening) then it's probably a bad gas valve coil (see below). If the glow-bar lights, then turns off (in about a minute) and the gas valve clicks on (and you can hear and/or smell that the gas valve is open) the burner tube holes are plugged and/or the glow-bar needs to be adjusted closer to the burner tube. To clean the burner tubes, you can either shoot compressed air into them, or remove them and run water through them. If it's an older dryer it's best to remove them and run water through them so as to get all the compressed lint completely out.
If you have a spark ignition (looks like a spark plug wire from a car...in fact it is.) The way that this system works is, instead of lighting the gas with a glow-bar, it lights it with a spark. To test the system, open the burner cover, turn the dryer on in heat mode, you should hear the gas valve click, and the spark igniter sparking, (in fact, it may even light the gas, but then goes right back off.) If this is the case then most likely the ignition cable is bad. Most people think that just because they can hear the spark, and see the gas light that the cable is OK, however, the ignition module sends a small amount of voltage the opposite direction through ground, through the fire, and through the high voltage ignition cable back to the ignition unit to let it know that the gas has lit. If the ignition cable has a even the slightest crack in the carbon core cable; that small amount of voltage cannot jump that crack like the higher voltage.... So replace the cable. (if it's a weekend and your faced with a downed dryer; either buy one from an auto parts store, or borrow one from someone's car...) The other thing that it may be is plugged burner tubes, if it looks like there is a lot of lint in the burner compartment you may want to try blowing out the burner tubes or removing them and rinsing them out with water.

Check circuit breaker. If it's a 220V machine be sure you have all legs of your power.

Check your neutral leads (I can't tell you how many times I've seen wire nuts come loose...) I've also had alot of power cords (especially 120V) go bad; check them.

Check control fuses, there's usually more than one. Sometimes they put them in the computer control board.

If there is a transformer in the main circuit (There may be two-one for the heat circuit, the other for the control circuit) be sure to make sure you have incoming and out going voltage according to the schematic voltage or it should say on the transformer.

Make sure door switch is adjusted properly or hasn't failed.

Check belt or chain.

Check the conduit going into the motor, sometimes older motors get hot and the mount fails causing them to rotate in their craddle and pulling out the conduit and wires. After repairing the wires you can run a large hose clamp around the motor so as to secure it. This will keep you going long enough until it's replaced.

If the dryer works only while you hold the start button on, it means the start circuit in the motor has failed (120V - 220V single phase system) I've seen people put tape over the button, however this should only be a temp. fix...replace the motor. For a three phase system, it's most likely the start relay is bad.
Be sure to check the main start contactor, these seem to fail quite frequently, they are usually located behind the dryer in the rear control panel.

Lost glow plug function


Had same thing happen on my New Holland 1630. Took the buss bar off the glow plugs and pulled them out and tested with test leads on the battery. They glowed. Put a volt/ohm meter on the buss bar and turned the key to glow position, no 12 volts present. Checked for blown fuse, nothing blown. Looked at relays. There was a glow plug lamp timer next to the start relay. Wiggled wires going to timer while asking for glow with key. Saw the glow lamp flicker. Took timer out and opened it up. Found a broken solder joint on circuit board resulting in a loose capacitor. Soldered the crack and put back on tractor. That was it! Glow plugs work now.

Magic chef self ignitor top,, how do u get the oven to work.. is it self ignite too. i turn on oven ger a glow in the oven,, dont know the model ,,older stove. good shape. bought house with gas stove...


If the glow bar is glowing and the oven doesn't come on in about 30 - 45 seconds.... it probably is the glow bar that needs to be replaced. BUT it could be the oven valve. Usually it is the glow bar.
The glow bar is wired in series with the oven valve and even if it is glowing it may not be sending the correct voltage through to the oven valve. To change the glowbar... unplug the appliance, unscrew 2 screws holding the metal bracket to the burner and remove the ignitor. You can cut the 2 white wires going to the ignitor and use ceramic wire nuts with the new ignitor.

Gas dryer turns on but won't heat up?


There is a little cap on the front of the dryer you can pop off and look in to see if the glow bar is glowing when the dryer calls for heat. If the glow bar does not glow chances are it needs replacing. If the glow bar is glowing it could be a number of things.
It could be one of the coils on the top of the burner is burnt out. It could be the glow bar sensor is not working. (a black box with two wires comming from it located on top of the burner funnel). It could be a thermostat not working.
The first thing to check and this has happened before. Make sure the temperature switch is set for heat and not air dry.

Heat no longer works


Is this a gas model? Does the glow coil get bright orange then go dark? You would want to measure the current on the glow coil if this is the case. It could be a weak glow bar/coil or bad coils on the burner. This all assumes the thermostat is sending full voltage to the burner. Please do not hesitate to ask more questions.
