Thank you for your question and I understand your concern.

I'm not clear in understanding the symptom or what you mean by "Miser Dry". I do not see a "Miser Dry" cycle on your model. Is the dryer not starting or not heating on the cycle you call "Miser dry"? I can't see how it would start, run and heat on high heat auto dry, time dry high heat, air dry but not start and heat on automatic low heat cycle. It may not heat at first if you have been running the dryer on high heat then flip to low heat because the thermostat may have already cycled the heater off. Start the dryer on automatic low heat after the dryer has cooled down to see it will heat.

I added a wiring diagram below that may be helpful in checking to see if you have the timer wired correctly.

I must assume it will start and heat on Automatic Cycle (high heat), Timed Drying Cycle (high heat), Air Cycle but it will not start and run on Automatic Cycle (low heat).

Reply with additional information and details so that I can have a complete understanding of the symptom.

I added a link to the Owner's manual in case you do not have one.

Thank u...the automatic dry-miser is the problem...I can use timed drying and air fresh..they work perfect...but the dry miser will not work on high temp...when i push to cool down it runs..this is when the dryer is just started or after running..that is why i wonder if the wires are wrong or the timer is bad..it would be helpful if the diagram had more detail...color of wires etc thank u

Larry: The wiring diagram that I added in the previous response has a drawing of the timer with the timer terminals marked by wire color. Check the part number on the timer to make sure you have the right one. Also, were there any instructions with the timer? The timer should be part #3396047. Did it have any jumper wires you forget to connect? If you have the correct part number I recommend calling a service technician to diagnose the failure.

A:

I know how great it can be to have a good working dryer so that you can dry your washed clothes. While you are waiting for your expert answer, I suggest you add to the thread of this question and include the full and correct model number of your dryer so that the expert can provide you with a more detailed answer. I did manage to find a link that describes a similar problem to the one that you are having with your dryer. I hope my link is useful.

I think that we may have already answered your question on how to connect these components. Here are links for the previous questions: whirlpool dryer part 3395395

on dryer ler7646aw0...i tested fuse with ohm reader...that appears not to be prob.i tested door switch not prob..put new switch in..not prob

The wires can be connected to the buzzer in either location as long as you have the correct wires attached to it. It should not matter which contact the wire is connected to. The wire colors do not seem to match the colors that are indicated on the wiring diagram.

If you are not able to get the dryer running, I recommend that you have a service technician physically examine the dryer and check the wiring. Here is a link for the Sears Service website: Sears Home Services .

You are probably referring to our Expert Joey who told your that the attached item is a power resistor. That does sound correct. Joey and I discussed this problem that you are having. He provided you with information for testing the motor. If the motor is good then you probably have a wiring failure or a bad timer. I recommend that you have a service technician examine the dryer and determine the cause of this failure. A wiring failure or timer problem is often difficult to diagnose and repair.

The wiring diagram for this dryer is shown in the image below. The wire colors are not shown on that wiring diagram. To wire up that start relay properly, you will need to trace the wires. The wire from the BU (blue) spade on the timer should be attached to the R1 contact on the start relay. The wire that goes to the motor should be attached to the R2 contact. The other wire should be attached to the CT1 contact. This information may help you connect that relay. If you need more help with that component, reply with additional details.

If the start relay is properly connected, the dryer may start. If not, I recommend that you check that door switch for continuity when it is closed. Be sure that you unplug the dryer before accessing internal components. A problem with the timer contact T to W (tan to white) can also prevent the motor from running. A blow thermal fuse or a bad drive motor can also cause this failure. If you need help checking these components, reply with additional details and we will assist you further.

This may be a difficult failure to diagnose and repair. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

The buzzer should have a tan and a black wire attached to it according to the wiring diagram that I sent. The 3rd white wire that you describe for the start relay sounds correct. I assume that you connected that wire to the CT1 contact. Since the timer motor is running, I assume that you are trying to start the dryer in the timed cycle. This would indicate that the door switch is good and the wiring from the tan wire to the connection at the outlet plug is okay. It also indicates that the timer contact BK - BU (Black to Blue) is good. I added a link below that shows how to check continuity through the thermal fuse. If you did not check the fuse in that manner, then I recommend that you recheck it. The location of that fuse is shown in the image below. It is on the blower housing beside the operating thermostat. Be sure that the dryer is UNPLUGGED when accessing internal components. If that fuse is okay, I recommend that you check the continuity through the timer contact T to W (Tan to White). With the dryer still UNPLUGGED, remove the white wire from the timer and check the continuity through that contact with the dryer dial set in the middle of a cycle. You should measure around zero ohms of resistance through that contact. If not, then the timer will need to be replaced if you made that check correctly. If you perform all of those checks and you do not find the cause of your problem, reply with additional details and I will provide you with testing information for the motor. The motor is more difficult to access and check than these components.

I am not sure which console switch that you are asking about. The image below shows a parts diagram of the components in the console. The temperature switch should have violet and blue wires going to it. The timer will have the colors that are noted on the wiring diagram and the drawing that I provided in my previous response. The wire colors will sometimes fade. There is a chance that the wire colors will differ from the exact colors noted on the wiring diagram. Reply with additional details and digital pictures if possible regarding this console switch and I will try to help you further with that issue.
