I have a fairly new LG Dryer (about 4 years old), and I'm not getting any heat out of it. I checked all the usual culprits, breakers, thermal fuses, heating element. I even replaced the heating element and the control pcb, following the service manual's troublshooting steps. Not sure where else to look.

Usually the THERMAL LIMITER on the side of the heating element housing fails (located at the center).

If that shows continuity and is "good"---next is to check the MOTOR CENTRIFUGAL SWITCH for continuity. There are two larger wires at each end of the motor plug/connector.
Remove the plug to the motor and check for continuity at the terminals where these wires connect to the motor switch.
Slide the *black ring* on the motor shaft inward---a "good" centrifugal switch will show continuity when the black ring is moved to the *run position* (inward).

Check the TERMINAL BLOCK for wiring damage. This is where the dryer power cord connects to the dryer.

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"

The heater element came with new fuses on the side, so that's not it. I did check the terminal block for wear, but looked new. I'll give the centrifugal switch a look at when I get home. Thanks!

Ok, so I finally managed to check the centrifugal switch. It had a bit of lint on it, so I cleaned it off, checked the connections and it worked the way it is supposed to. Did I miss something? I checked the power again and reset the breaker, just in case. Checked the continuity across the heater element, fine; across the fuses that are on it, fine. Now I did notice something, I'm getting 120V to each leg on the power cord, but across the two, I'm getting almost 0V, reading about 70mV.

Something else I found curious, I checked the voltage going to the heating element. From every pin to ground was 120V, but across the blue and yellow, I'm getting nothing. It seems that I should be getting 240V there. Anyone?

Check voltage at the WALL RECEPTACLE.

Unplug the dryer.

If using a 3 PRONG PLUG / RECEPTACLE : 220 volts should be at both *straight* pins of the RECEPTACLE.
120 volt should be at each *straight* pin and the "L-shaped" ground/earth of the RECEPTACLE.

If using a 4 PRONG PLUG / RECEPTACLE: 220 volts from the *straight* pins of the RECEPTACLE.
120 volts between the *straght* slots of the RECEPTACLE and either of the *round* & "L-shaped" ground/earth slots of the RECEPTACLE.

If any of this is incorrect---contact an electrician.

Well that seems to be it, I'm getting 120V on one leg, 20V on the other, with only 90V between the two. I swear I checked it before and was getting 120V on each leg. But the dryer was still connected, maybe that's what caused the difference in readings. I'll have to wait until Monday to call someone in, but I'll let you know what happens. Thanks for you help!

and you tried re-setting the Circuit Breaker ?
seems like the Circuit Breaker just needs replacing

Finally got someone to come look at it. I'm renting so I had to wait for 'their guy' to come. Turns out it was a bad breaker. Lesson learned: always check voltage without anything plugged in. Side note I now have a spare heating element and control pcb in new condition if anyone needs it. Thanks for all the help!

Unfortunately I didn't get the parts from there. I went the cheap route through eBay.

always check from both legs to common and leg to leg.
The 70 MV reading between legs was the sign that you had an electrical problem.

Yep, I learned a lot from this. But now I know for the nest problem.
