Just finished installing the 2nd brand new blower/drum motor in 2 weeks, and now it won't stay running, even on "Air only" setting with no heat.
Two weeks ago when it just died, I went on partselect.com and stepped through all of their suggestions for metering out everything until I got down to the motor, and it metered out of spec. Diagram calls for 2.4-3.6 ohms on the main and 2.4-3.8 ohms on the start circuit. Start was fine, but the main only showed 0.3-0.7. So I ordered new motor from RepairClinic for a hundred bucks, plus an impeller, cause you can't get an old one off of an old motor shaft apparently without cutting it off. So no big deal, part arrives and just being myself, I metered the new one and it only showed 1.7 (steady flat reading) on the main. But I wanted my dryer fixed, and it ain't that hard to do, so I just shrugged and bolted everything back together with the new motor. Fired it up- ran like a champ 2 loads of laundry dried that night no problem.
Next day, wife puts in a load, starts right up runs about 10 minutes and shuts off. (Wtf?) Spun the settings dial, hit the button and started up again ran a good while, thought it had cut off because load was dry but we didn't check until the next morning only to discover the previous night's load was still barely moist. So close to dry you could just barely tell, but not totally dry. Set the dial hit the start button-Nothing.
Ran through the whole circus again metering everything from the little fuse, start switch, timer relay, really everything back down to the motor once again. Figured it had to have something to do with the 1.7 reading out of the box, pulled it out, checked it and now it would only show 1.3-1.5 on the main. Called RepairClinic, explained everything, they sent me a new unit and comped overnight shipping. Just got it back together, started it on "auto-dry high heat", ran fine for a couple of minutes so I put another load of clean clothes in. Started dryer on "auto dry high heat" again, it ran about 4 minutes and stopped. I didn't touch anything, pushed the start button and it ran again this time for 8-9 minutes, shut off. Thinking it may be an overheat issue that somehow I hadn't been able to find so far, I changed setting to "Fluff Air No heat", hit the start and it ran fine for about three minutes and sounded like it was going to cut off for just a second, but caught and kept running. Like a dang car with a miss or something (? really weird?). It did that and kept running maybe 4-5 more times over the next 10 minutes and then one time when it stuttered it did not catch and spool up again and shut off. Pushed the start button and now back to nothing. No response on any setting. Now what ?
