    Question Gas dryer tripping circuit breaker

    MayTag gas heated dryer Model LDG8606AAE has begun to trip the breaker mid-load. If I flip the breaker back on and start the dryer, even immediately (without letting anything cool down) the dryer works fine for awhile longer. Sometimes it will make it through a full load without tripping but usually not. On reflection, it seems that if I'm on air dry/fluff mode the breaker never trips....hmmm

    This dryer is on a dedicated 20Amp circuit. The first thing I did was change out the duplex, then the breaker to make sure there were no problems with the electric supply. Symptoms continued. Just to be sure new circuit breaker was not bad I ran an extension cord from another circuit - symptoms continued. So I know the problem is with the dryer itself.

    Now thinking:
    • there is either a short somewhere, either between cord and motor or in motor.
    • the motor is getting bound up somehow causing it to pull too much power resulting in the breaker tripping


    As a side note, the drying does sometimes make a squealing noise making me question bushings? or belts...

    I'm about to Figure out how to open it up. Maybe there will be an obvious burn-mark somewhere...I'll pay special attention to the electric leading to the ignitor since it seems to be tripping when I'm using one of the heated dry modes...

    If not, I think I will need to test the various components with a voltage meter, which I have, but I haven't learned how to use it for this purpose.

    Any ideas on what may be tripping the breaker?

    I pulled the panel by removing two screws on the bottom panel, swinging out from bottom and unclipping from the top.

    Will I need to go deeper, like removing drum?

    What is process for testing the health of the motor?

    Any assistance will be greatly appreciated!

    Trying to post photo but even lowest resolution is being blocked as being too large....

    Opened front panel and noticed two things right off. Very fine metal shaving have dropped along the front end of the ground, amongst lint deposits. Also an evident short (scorch mark) can be seen to the left hand side on a red-cased wire linked to the Thermostat (Manufacturer Part # WP3387134). Hoping that the short was literally caused by metal shavings bridging across wires, I vacuumed the area out, closed it up and tried starting again with a medium heat setting. Circuit tripped after approximately 5 minutes.

    I ordered a new thermostat.

    Any advice?

    Hi,

    Check the front glides, when they wear we get metal on metal and shavings near the front.

    the drying does sometimes make a squealing noise
    Often motor, idler pulley or drum support wheels...

    First off, thanks to Jeff1 for the tips to stop the squeaking. I did order 2 front drum support glides and drum roller support kit and will install soon.

    Following up to confirm that replacing the cycling thermostat that had the noticeable scorch mark (as in short) was super easy to do and did fix the circuit tripping symptom. I wish I could post a photo because it is interesting how hot the arc must be to burn a small hole through the (aluminum?) thermostat housing. The dryer now operates fine albeit noisy.

    Apparently this particular failure doesn't occur very often because all the advise i found concerning a possible short in the dryer pointed me back to the electrical circuit.

    Hopefully the new front glides and rollers eliminate the creation of metal shavings and quiet the squeal.

    Correct, only once in a while do we see this.

    Okay, new gliders and rollers arrived so I opened her back up. Was amazed how many new metal shavings had been created in just 2-3 days doing 3-4 loads. I'm reasonably convinced that the metal shavings landing on the wires connecting to the cycle thermostat caused the original short.

    Changed out the gliders/rollers without many glitches -- old rollers were not spinning freely but they are now. Reaching in and removing the belt looks a lot easier in the repair video than it was for me to perform - I had a belly laugh thinking of how hard it will be to reach in there and thread it back on....still haven't done it...I was surprised to see that the belt rides along the fat part of the tumbler about 2 inches inside the recessed groove that I had assumed would be used as a track for the belt.

    Closer observation of the tumbler (drum) in the area that was to ride across the glider pad revealed a couple things, neither good. The white enamel paint had been scrapped off so now it is shiny metal (not white enamel) and the edge of the drum had worn through to the point that a thin strip of metal along the rim was loose. I used a dremel tool to cut the loose strips off and file down the edge created by my cut. I noticed that the felt along the front rim had been worn and ordered a new felt strip that I will get to later.

    I found that the tumbler replacement part has been discontinued by Maytag/Whirlpool, which is a bummer. I'm going to try to replace the drum/belt now. I was thinking of flipping the drum (symmetrical) to put the worn side on the rollers rather than the glider but at least for now hate to place the less than perfect edge against the back felt ring which is in great shape - probably better to leave it toward the front at least until the new felt strip comes in.

    Any words of wisdom would be appreciated. Thanks Eric (aka Logcabin1)

    Wow! I knew that belt wasn't going to go back on easily and it didn't. I lined the belt up with the visible mark outside the drum showing where the belt has rode for 20 years and it seemed the belt was too short to reach around the drive motor pulley even with the spring tension released. It turns out that I had not carefully wrapped the belt closely around the tension pulley so the belt was on the outside of the metal guide. Once I focused on doing that, I was able to get the belt wrapped around the motor pulley. Big sigh of relief.

    Super quiet dryer operation has me smiling and thinking the job was well worth the effort. I wasn't feeling that way a short while ago struggling to get the belt back on the pulleys.

    If not overly bad, I just paint it.

    I also have turned the drum around when needed. Not much else you can do unless you find a good used drum.
