Your dryer not working as expected in the time of need can be quite frustrating. There can be a lot of things that can go wrong. And a blown thermal fuse is a very common one.
How to replace thermal fuse on a Kenmore 90 series dryer?
First, unplug the dryer and turn off the gas for safety reasons. Check the igniter if it’s working fine to completely diagnose your dryer. Locate the igniter and check its resistance. If it’s alright then move to the thermal fuse. Locate the thermal fuse and check it. Replace it if it’s faulty.
Confused? Worry not! Because this detailed step-by-step guide will guide you through the process with ease.
Guide on Replacing the Thermal Fuse
Did your gas dryer go out after a few seconds? That might be because of a blown fuse. But don’t worry! Replacing the thermal fuse on your Kenmore 90 series dryer doesn’t take a lot of skills.
A few simple steps will be enough to replace the thermal fuse. But, It’s crucial to follow the procedures accurately. Otherwise, it may damage your dryer.
So ready to follow the steps? Let’s move on!
Step 1: Unplug the Dryer
Unplugging the dryer is a must for safety reasons. Every part we are going to work with will have an electrical connection. So you might get shocked if you don’t unplug the dryer. Unplug the dryer and then get into the next step.
Step 2: Turn off the Gas
Turning off the gas is also due to safety reasons. Even though it’s not as important as unplugging the dryer, it’s still ideal to turn it off. Also make sure that the valve handle is parallel to the pipe once it has been turned off.
Step 3: Locate the Igniter
It’s important to check the igniter if it’s working right. It must be helpful in pinpointing the problem. Also, ensure that replacing the thermal fuse will be enough.
Press down the two spring clips that are located on the top edge of the lower panel. You can press them down with a flat screw or anything of that sort. Once pressed, pull out the panel.
The igniter should be found on the right side, a little to the left of the gas valve.
Step 4: Check the Resistance of the Igniter
Checking the resistance of the igniter will help us determine if it’s bad. Locate the white connector and disconnect it. Now attach your multimeter leads to the two ends of the wire in the connector.
Take the reading of the multimeter. If the read is between 75 to 100 then the igniter is good. Place it as it was and proceed to the next stage. But if the igniter is bad then you need to replace it.
Unscrew the igniter and replace it with a new one.
Step 5: Remove the Lint Box
Pull up the lint screen and keep it aside. Remove the two screws that you will find on the lint box. Once you remove these screws, it will slide down.
Step 6: Locate the Thermal Fuse Check the Resistance
Finally, we’ve come to the thermal fuse we were looking for. Thermal fuses can blow out for many reasons. For instance, extension cords can very likely be the reason for blowing your fuse.
The thermal fuse is located on the top of the black box. There will be two wiring connectors. Pull one of them off of the fuse. Now check the resistance.
Since it’s a fuse the reading will be 0 ohms. If you find the fuse blown then you will get an open circuit overload. But don’t worry, the thermal fuse is very cheap and easily accessible.
Here are some recommended ones if you are worried:

|AMI PARTS Dryer Thermal Fuse||Made from durable high quality material|
Now that you have your fuse in hand, it’s time to replace the old ones with these.
Step 7: Remove the Old Thermal Fuse
You will find two ¼” screws holding the fuse in place. Remove them carefully with a ¼” socket wrench. Unscrew them carefully and beware of dropping them inside the dryer. Once it’s removed, it’s time to install the new fuse.
Step 8: Reinstall the New Fuse
Which wire it connects to doesn’t really matter. Also, the direction it goes doesn’t matter as well. So screw in the hex head screws that you removed earlier.
Reconnected both the wires to the terminal fuse. Once you are done replacing the fuse, close the lint screen box. Remember the step how you have removed the lint screen box.
Step 9: Test the Dryer
Now comes the best part. It’s time to test the dryer if it’s working like before. Plugin the dryer and turn on the gas line to test it.
If the dryer is working then well done.
Question: What tools do I need to follow these steps?
Answer: You will need three tools. You will need a multimeter, a flat screwdriver, and a ¼” socket and ratchet.
Question: Is there any safety equipment I should use?
Answer: You may use a pair of gloves to be safe from hurting your hands. This can also help prevent getting shocked in case you forget to unplug the dryer.
Question: Are there any other possible reasons except bad igniter and blown fuse?
Answer: Yes. A malfunctioning thermostat is often the cause of a dryer that isn’t functioning. If that happens you need to have to replace it using a new one.
Our guide comes to an end now. We hope that now you know how to replace thermal fuse on a Kenmore 90 series dryer. But remember to prioritize your safety first.
