Question and Answers


What else can be wrong with a Whirlpool gas dryer model LGR7648PQ0 when it runs but doesn't heat and the igniter is new?


If an gas dryer is running but not heating the most likely cause is an open thermal fuse. If the igniter is not glowing and it is new then I suggest you check the thermal fuse which is located on the blower exhaust in the rear of the dryer.

See the 2 images below for how to access the thermal fuse on this Whirlpool dryer. Remember to unplug the dryer first.

The 3392519 fuse can be checked two ways. The proper way is to check continuity across the two terminals and see if there is a circuit. If the circuit is open then the fuse is bad.

If you don't have a meter or know how to use one then there is another way to check if the fuse is the problem if caution is used. With the dryer unplugged you can remove the two wires off the thermal fuse and join (jump) them together with a small piece of wire. Put a little electrical tape around the connection and don't let it touch anything metal. Then carefully plug the dryer in and see if it will run and heat. If it heats you have found the problem. Replace the fuse right away and don't try and catch up on laundry with the fuse bypassed.

The 3392519 fuse can be obtained from the following site: SearsParts Direct .

I hope this information is helpful to you in resolving this problem but submit another question with any additional details for further assistance.
