MT dryer MDET336AYW element not functioning

15 posts in this topic

To the Dojo,

 

I went out on this dryer; I measure 120VAC at each leg of the element, and it ohmed 10.1 ohms of resistance. I swapped the old element out with one I had...nothing. Where on the timer do I need to measure voltage? Experience or insight? I welcome your critical comments and snide remarks.

 

Thanks in advance,

Tyrus

That's the same 120 on either side...need to test across both for 240. What's the status on the thermal cut out and high limit?

 ... 120VAC at each leg of the element

... and it ohmed 10.1 ohms of resistance.

1) not a normal test on a 240v appliance

2) Element is good

 

Does the Drum Light work when the Door is open ?

Is there 240v at the Dryer Power Cord Terminal Power Strip ?

if OK, then set the Temperature Switch to Air-Fluff (no heat)

Then measure for 120v from each side of the following to chassis (ground):

Cycling Thermostat Blue wire / Purple wire

Hi-Limit Thermostat Purple wire / Black wire

Reg,

 

I discovered the door switch and light are wired incorrectly, i.e. the drum comes on when the door is closed. I will use the diagram and take care of that problem. There is 240VAC at L1 and L2 on the power cord. On Air Fluff, there is 120 VAC at Cycling/Purple and Hi-Limit/Black. Is this like the situation with the service-through-the-front WP dryers with the dryer relay; I had this problem with a couple stuck relays and had to change them. In this situation, though, I'd change the timer, correct? I see no such heater relay on the diagram.

 

Thanks in advance,

Tyrus

... On Air Fluff, there is 120 VAC at Cycling/Purple and Hi-Limit/Black.

and 120v at Cycling Blue ?

 

if OK then:

set Dryer to run High-Heat on Timed Dry

check voltage from Timer yellow to Timer red

Should be 0v

If 240v, then bad Timer

Misunderstood your cycling voltage check; will-do a recheck. Thanks, Reg.

Cycling thermostat Blue to chassis--120VAC

Cycling thermostat Purple to chassis--120VAC

Hi-limit thermostat Purple to chassis--120VAC

Hi-limit thermostat Black to chassis--120VAC

 

Red to Yellow on Timer--0VAC.

Red to Yellow on Timer--0VAC.

That's with the Dryer set to run High-Heat on Timed Dry ?

 

OK, with the same setting...

on the 3-position heat switch:

measure voltage from Red wire to Blue wire

0v = OK

240v - bad Switch

AUTOMATIC High Heat--no timed High Heat. This dryer feels like Foreigner's, "Feels Like the First Time," Kurtius; thanks for the grief, bro.

once more :

Air-Dry:

3 way Temperature switch

red wire to chassis (ground) = 120v

blue wire to chassis (ground) = 120v

 

Cycling Switch blue to purple = 0v

 

High Heat

3 way switch

red to blue = 0 v

What I got

 

Air-Dry:

3 way Temperature switch

red wire to chassis (ground) = 123VAC

blue wire to chassis (ground) = 123VAC

 

Cycling Switch blue to purple = 0v

 

Auto Dry, High Heat

3 way switch "REGULAR," red to blue = 0VAC

Cycling Switch blue to purple = 0VAC

 

So, because the timer and thermostats are functioning okay, don't I change the heat selector?

:kopkrab:

 

could be bad (weak) Motor Switch contacts ....

 

Auto Dry, High Heat

Timer Yellow wire to Timer Red wire = 0v (that was done)

 

3-way Switch Red to Blue = 0v (that was done)

 

Cycling Thermostat Blue to Purple = 0v (that was done)

 

Hi-Limit Black to Purple = 0v

 

Drum Motor Black to Blue = 0v

 

Heater Black to Black = 240v
