Question and Answers

Q:

DLG5988w dryer will not heat dlg5988w

A:

Thank You for choosing Sears PartsDirect.com. I regret to hear that you are having issues with your dryer and do understand your frustration. Glad to help out. Im looking at your model number dlg5988w and if your glow bar/igniter is glowing, it seems like the gases are not being release from the valve to create the flame.  Sometimes if you try tapping on the valve it may unstick if it is sticking. 

I have included a link to our PartsDirect page where you can purchase the part you need to complete your repair. Just click the blue link below to be taken to the page.
 
If you have further questions please let me know.
Thanks for choosing Sears PartsDirect.com

I attached the link below for you to view. I hope the link that I provided is helpful. Have a nice day!

A:

This is a gas dryer and from the description you give I suspect the ignitor or flame detector is shorted. The coils on the valve us DC voltage. One thing to try is to disconnect the ignitor and see if the breaker still trips. The image below may be helpful to you. Remember to unplug the unit first. I hope this helps. You can reply with any additional details for further assistance.

I replaced all these part and disconnected the ignitor, still trips breaker, lol. I looked under the parts list and didnt see the flame detector. Maybe I missed it? And other thoughts?

A:

I'm really suprised the breaker tripped even with the ignitor disconnected. One simple thing to try next is the select the air dry cycle. The air dry cycle only runs the motor. If the circuit breaker trips then I suspect the motor is the problem. A clamp-on amp meter can be used to check the ampere the motor is running. If the motor keeps drawing higher and higher amps then it would be the problem. If the voltage is low at the outlet then the motor will draw more amps. If the breaker trips before the amps exceed its rating then the breaker might be weak and be at fault.

You indicated that you have the service manual. I provided some additional technical information in the images below that may help you diagnose this heating failure in your dryer.

NOTE: Follow electrical safety guidelines when servicing this dryer. Use extreme care when testing components in the dryer. Unplug the dryer when accessing internal components. If you need to plug the dryer in to test a component, be sure that you unplug the dryer as soon as testing is complete. Avoid contacting live components when testing the dryer with internal components exposed.

If you have not checked the thermostat using the information shown in the first image below, I recommend that you test that component. The second image shows technical information for the gas valve assembly. The third image shows a diagnostic test program that you can use to check the temperature sensors. You could have a wire harness problem that is preventing the dryer from heating. This information should help you perform additional tests to determine the cause of your problem.

If you need more help, reply with additional details and we will try to assist you further.

This can be a difficult system to diagnose. If you get to a point where you need a service technician to physically examine the dryer, you can schedule one through this link: Sears Home Services .

Hey Lyle...thanks for the info...I will try it this weekend. But one question, How does a wire harness go bad? And is there some way of checking it out?

A:

The harness can be pinched or damaged during production or access of internal components. The connectors can become corroded or they can also break. If you have a volt/ohm meter, you can check for continuity (near zero ohms of resistance) through the wire harness using the wiring diagram as a guide. A loose or corroded connection is the most common failure in regards to a wire harness failure.

OK... I think I am an expert on Dryers now...LOL....had the repairman come out....he was there 5 min and had the answer....The dryer had back pressure from the vent....apparently, birds clogged the vent outside....HERE is the test: Open the door to the dryer...hold the safety button down that tells the dryer door is closed....turn on the dryer....pull the filter out and stick your hand down where the filter goes....you should feel a slight suction....if you don't..you have venting issue!

The Number one cause with this dryer not heating up is your duct work is clogged so the ignitor doesnt kick in, or it kicks in and turns off.

Hello Jared. You appear to be correct about that #1 cause of this dryer not heating up. Checking the vent system should be the first issue that is addressed for a heating problem in this type of dryer.
