The problem is intermitent heat (at best). With the front lower panel removed, the igniter is observed starting to glow and getting quite bright for 10 or 15 seconds, then passively cycles off for about 60 seconds. The ignitor then repeats this cycling process again and again. About 2 of 25 times a nice blue flame ignites obviously producing heat but only lasting a few minutes. Would you be good enough to share suggestions?
Answer Hello John,
While the best way to check the ignitor is with a clamp on amp-meter and look for 3.2 to 3.6 amps of current draw, you can tell most of the time if the ignitor is bad by the color of the glow. If it's red, it's bad. If it's orange, it could be good or bad. If its almost white or white hot, it's good. If the ignitor is in fact good, the issue will either be a coil on the gas valve or the gas valve itself. If you could re-post with the mfg number, we can look up the correct part numbers for your model.
My dryer is a gas Amana LG50AW. It heats up for a few minutes at the beginning of the cycle and the cools down and blows cold for the rest of the cycle. The dryer has to sit and cool down for a while before it will heat up again.
Answer Dan, Based on your post description, you either have a weak gas supply issue, or a "bad set of gas valve coils 279834 (thats most likely the issue) You'll need to remove the lower access panel ( 2 screws in the bottom of the panel, 2 locator pins at the top of the panel) and observe the gas valve operation, When the dryer starts you'll hear a click, the igniter will glow for 30 to 60 seconds, the igniter will start to fade and the gas should ignite, after a few cycles of the valve, you'll probably notice the igniter glow and cycle off but no gas released and no ignition, The coil winding has opened, and the solenoids are not lifting the plunger in the valve. Thanks and Good Luck
The dryer heats up for a couple of minutes at the beginning of the cycle, then blows cold air for the rest of the cycle.
Answer Hello Dan. It sounds like the coils 279834 may be bad and will need to be replaced. Check the coils 279834 and see if they test good. You can test the coils using a multi-meter TJMA-DM1. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Test the coils after running the dryer for about 10 minutes. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
