there must be 240v from Black to Red
Has this Dryer worked OK up till now at this location ?
Have you re-set your House Circuit Breakers ?

[sh2sh2]

if there is no 240 from black to read but there is 120 from black or red to white then one of the legs is open and 120 is feeding through the dryer to the other leg...unplug the dryer and test the outlet by itself, you wil find one leg has no power. Lesson learned. When you find nothing wrong with the appliance look elsewear for the problem. Time to call in the electrician

Yes, dryer worked for almost 3 years at this location
I did reset my circuit breaker before taking the dryer apart.

At the outlet, theres 125V from each side, and 250V when both sides are connected.

[sh2sh2]

but at the terminal block you said there was 0 from black to red? if so there must be a opening in the power cord or the outlet is not making good connection with the power cord?

[triggerhappy007]

I noticed I hooked up the power cord wrong when I first installed it. I mixed the red and black wires up and had the ground from the power cable going to the white. Now I redid the cables so the ground from the dryer is going to the white, red to red, black to black, and ground from the power cord going to the ground on the machine.

It's getting 250V from red to black of the terminal block. Now, the dryer doesn't turn on at all.

[triggerhappy007]

I just checked red to black at the terminal block and it's only 125V now.

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

If the 2 low voltage plugs (for the front control panel) were removed from the MAIN BOARD during your various tests---verify that both have been re-installed (black and white multi-pin connectors).

Forgetting to re-install these 2 plugs will result in a "dead" dryer (no lights at all).



If the Control Panel "awakens" (lights are on)---verify that the DRUM BELT is installed (dryer will not start with a disconnected/broken belt).

Yes, dryer worked for almost 3 years at this location

How could it have been working for 3 years if the Power Cord was connected wrong from the original installation ?

Is this a 3 wire OR 4 wire Outlet ?
Is this a 3 wire OR 4 wire Power Cord ?

If the Dryer isn't wired correctly, it could blow the Controller.

I double checked to see if they were connected and they were.

RegUS,
I'm not sure why it worked, but it did. I have 4 wire outlet and a 4 wire power cord. It's weird, I checked the red and black at the terminal and it was 250V, then I assembled the dryer together and check it, but it's only 125V now.

[john63]

Possible faulty POWER CORD.

Check continuity of each wire-to-the-plug terminal.

Bend/flex the plug while testing each wire to see if a "break" in continuity occurs.

If it does---new POWER CORD needed.

Can you measure voltage across black/blue of the heater relay while machine runs on a heating cycle ?

[]

Also measure each of the black/blue to a good ground

I do believe I've learned a thing or two around here - that's where I was going next. (ed.: oops, late post)

Do anther test at the Outlet...
May need more of a "load" than just a volt-meter.
If you have a table lamp, etc
Try test-wiring the table lamp to each of the 120v connections ONLY:
Black & Neutral
Black & ground
Red & Neutral
Red & ground

The reason the dryer might be dead now is when you rewired the terminal block you may have moved the working leg from L1 to L2 so now the controls dont have power. Try wiggiling the plug in the outlet and see if voltage comes and goes, shine a light into the terminals in the plug and see if they are shiny or burnt

This is probably the problem. I can see that one side is not making very good contact even though my test probe read voltage. I will replace the outlet today and see how it goes. Thank you everyone for your help.

Dayyam, the page is so old it blew dust in my eyes when I clicked the link! And what grade-schooler designed that page layout?

[triggerhappy007]

Replaced the outlet and everything works now. Thanks again for all your help.
