That means - what? Change the door switch? Use a meter to check the voltage? Page 15? I'm going to have to hire that out - I have no idea how to use a voltage meter!

I keep thinking I should go sign up for a class at the local Vo Tech for Electrician. I'd love to learn how to wire stuff up for real. My dad did that for a living - I wish I had gotten him to teach me before he died.

Regus & Kdog were on the "ball" here.

I made an error in describing how the THERMAL LIMITER functions in your **electric** dryer.

The electric model LG dryers will CONTINUE to run if the THERMAL LIMITER on the Heater Housing has failed.

The THERMOSTAT on the Blower Housing acts as a "self-resetting" Thermal Limiter for BOTH *gas* AND *electric* LG dryers.

If the THERMAL LIMITER on the Heater Housing fails (on 220v electric models) the dryer will be able to "run" but will not heat.

**********************************

On GAS model LG Dryers---a failed the THERMAL LIMITER on the Heater Housing will **shut-down** the dryer completely.

**********************************

Back to your dryer....

Judging from the amount of lint accumulation inside the dryer---this indicates that the venting was very poor indeed.

The MOTOR has *most likely* failed due to extended run times needed to dry laundry and from high-heat exposure caused by poor venting and heavy lint accumulation on the motor.

The inside of the dryer was an "oven" for a l-o-n-g time.

The MOTOR *overload protector* began to shut down the dryer as it became too hot during the cycle.

To eliminate:

Musty odor

L-O-N-G cycle times

Dingy/yellowing whites

Suds error message

Slow spin speeds

Intermittent water leaks (from rear of washer)

And other annoying symptoms which vary brand-to brand.

Read below:

The *correct* amount of HE (High Efficiency) detergent that should be used in any front load or agitatorless top load washer with tub sizes 3.0 cu ft and larger is as follows:

HE: (2) Tablespoons Per Wash Load

HE 2X: (1) Tablespoon

HE 3X: (1) Teaspoon

Perform a TUB CLEAN CYCLE every (4) months.

Use: "Tide Washing Machine Cleaner"

So I'm sitting at the Local Laundromat last night and I decided I want one of those babies. Extra Large. One where I threw in 3 loads of heavy winter clothes in - sweat shirts and pants, jeans, towels, sheets and everything - and it all dried in 20 minutes. Unbelievable. I can put it in my garage, can't I? :)

Yep, you can get 'em - I've seen lots of folks install commercial type machines in their home; bring a very well oiled chequebook when you go shopping though, and expect ALOT of added installation expenses

OK, I have an engineer that lives next door and he knows how to use one of those voltage meters. How does he check the motor - is it directly to the motor? Or is it through the control board? I assume the motor has to still be hooked up to the dryer to check it out, right? Otherwise, I'll just take it out and take it over to his house.

If you just push the ON Button it says CHECK FILTER.

"Check Filter" is just a reminder before every Dryer Cycle
To test the Motor, use the wiring diagram/diagnostics in the service manual

Is there any way to check the control panel / board to see if it is bad?

looking at the Wiring Diagram, when the Dryer should be running, if there's 120v across Controller connector BL2 pins 1 & 2, then the Controller is OK.

thanks.

we took it all apart again, checked the motor - which was OK, put it back together, and the dryer mysteriously fixed itself. Go figure.

I swear - this is the dryer from Hades.

Is there a picture somewhere on how the dryer belt goes on? I'm still not sure that it's on right. It seems like it's turning slower than it used to. Both belts go under the big wheel and then separate to go around the drum?

Yes, that's the picture we had to go by. It makes no sense in the real world.

The only way we could get the belt to fit is for both of the belts to go under the wheel on the left. And then they separate - to go around the drum.

But I was just drying a load of clothes and the drum stopped. So something is clearly not right.

the picture may be a liitle confusing

The portion of the belt that is on the top of the Motor goes around the pulley, and continues to the right around the Drum.
The portion of the Belt on the bottom of the Motor goes directly to the left around the Drum

<<<I was just drying a load of clothes and the drum stopped.>>>

**********



The BELT may need to be checked to verify correct installation.
Also verify that the BELT remains in the groove of the MOTOR PULLEY as well.



Possible failing MOTOR (overheats & cuts-out).

And no, I don't know what it is. I just pulled the dryer apart and saw it.

Looks like belt shavings, probably from the belt not being installed correctly resulting in the motor pulley spinning at a higher angular velocity than the belt itself. New belt time, comes with a 365 day warranty, even if you install it wrong==> http://www.repaircli...umber=DLE7177WM
