Whirlpool Gas Dryer Model # LGR7648KQ0 Not Heating

Hello, I am looking for a bit of help figuring out what the problem may be. The dryer will start but there is no heated air comming out.

I removed the plastic piece on the front and could see a glow for 5-10 seconds or so and then the glow fades. Then I removed the back and checked the sensor on the exhaust (I think the tempature sensor) and had resistance. Also checked the sensor on the heating side (not sure what it's called either) but it also had resistance.

Not sure what to check next and could not find a wiring diagram on-line anywhere. Can you please give me a direction to check next?

Thank you in advance. Have a great day.

Hello Nick. Welcome to the Gas Appliances topic and the Do-It-Yourself Web Site.

Most common cause for the problem/condition described is a defective solenoid. Located on top of the gas valve. There are two of them, each having wires with quick disconnects attached to them.

A quick search will reveal this forum topic already having hundreds of prior posts on the subject of dryers which fail to heat up and more detailed information HERE in the dryer sticky note.

Once you've checked for continuity and determined all is well, replace the two solenoids on top of the gas valve and you'll likely resolve the condition.

Also insure the venting system is in proper working order and free of all dust and lint. Exhaust hoods flapper door opening freely and there are no kinks, bends and/or restrictions in the venting tubing, etc.

Retail appliance parts dealers can also help determine what the most likely possible problem may be. They will need the make, model and serial numbers. Appliance parts dealers are an excellent source for original replacement parts and problem resolving matters. Dealers are listed in the phone book under appliances.

Be sure the electrical power to the appliance is turned off, before attempting any repairs or services. Always check for gas leaks whenever moving the appliance and/or a service or repair includes any connection of a gas part.

Read the existing questions on the subject of dryers. Doing so will more quickly provide you with answers to questions & provide additional information on how to resolve dryer problems.

Use the reply button to add additional information or questions. Using the reply button keeps or moves the topic back up to the top of the list automatically and keeps all communications on this subject in this thread.

It's always advisable to clean the entire exhaust venting system every 2 years. Or during any dryer maintenance, replacement and or repairs.
