Blown thermal fuses

I have blown two 91°C thermal fuses in the exhauts channel. After the first I cleaned out the channel ahead of the blower. There was quite a bit of lint build-up. I don't believe the screen had been cleaned often enough. Still it blew the fuse again. This time I blew through the ductwork with my electric leaf blower, A significant amount of lint came out, but I'm not positive that the duct was completely blocked. Am I likely to have the problem solved?

Heating element coil my have shorted to the metal housing. There should not be any continuity between the heater lead and the housing. Remove and inspect heater for any signs of heater coil touching the housing. Also as the heater gets hot, the coil may expand and touch the housing. If not sure, replace the heater.

I would think not. The MAIN cause of that fuse blowing is lint build up. Turn the dryer on and put your hand on the outside of the vent duct. Is the air blowing hard? If so, you will probaly be ok, if not maybe your blower wheel needs to be replaced...

Maytag Neptune Model #MDE5500ATW How to tell if the thermal fuse is blown


If this THERMAL fuse is blown it would not operate at all. If it runs but don't heat it probably is a limit or the heater. If you see a lot of junk in the vent pipe AND it still runs then the heater limits are gone. If the vent it clear but filter housing or blower has an issue then it won't run and the thermal fuse is gone bye bye.

Dryer won't start


This usually caused by a blown thermal fuse on the blower housing located behind the rear access panel. This thermal fuse is wired in series with the motor and if it blows, power to the motor is terminated and the motor cannot run. No dryer function works when the motor cannot run.

Unplug the dryer or disconnect power then remove the rear access panel. Locate the thermal fuse then bypass it for troubleshooting purposes.

Bypass the thermal fuse by disconnecting the wires and joining it together. Insulate properly and plug the dryer back in. The thermal fuse is indeed blown and needs to be replaced if the dryer starts. Do not use the dryer with the thermal fuse bypassed due to fire hazards.

Clean the lint filter and make sure the vent system is not restricted then replace the thermal fuse including the cycling thermostat (thermistor for other models) as a standard operating procedure and preventive measure. The thermal fuse usually cuts out due to a failed cycling thermostat(thermistor for other models).

My dryer is a kenmore 110.61082000 and it wont start. it keeps displaying check lint screen even though it is completely clean and the sensor bar is clean. what is wrong?


The thermal fuse located on the blower housing is blown and since it is wired in series with the motor, power to the motor is terminated, the motor will not run and no dryer function works. Disconnect power then pry the lower access panel off with a flat-head screwdriver as shown.

Remove the hex-head screw from the lint duct bracket and remove the bracket. Remove the two hex-head screws from the lint duct and remove the duct to expose the thermal fuse on the blower housing.

Bypass the thermal fuse by disconnecting the wires and connecting them together. Insulate them properly and plug the dryer back in. The thermal fuse is indeed blown and needs to be replaced along with the thermistor if the dryer starts. Do not use the dryer with the thermal fuse bypassed due to fire hazards. Let us know if you need further advice.

Our Whirlpool dryer model #LER7646AQ0 will not start. Door switch checks for power with a power tester. Put new start switch in and still doesn't work. Do I need to use Ohm tester or will power tester...


This problem is commonly caused by a blown thermal fuse located on the blower housing. The thermal fuse is wired in series with the motor and the motor activates a centrifugal switch for the heating element when it runs. These setup makes the dryer fail to start and the heating element not to turn on if the thermal fuse is blown. The dryer seems to no work at all. Verify the condition of the thermal fuse by bypassing it and starting the dryer.

Disconnect power then access and bypass the thermal fuse on the blower housing. The blower housing is located on the rear left bottom of the dryer cabinet. Remove the rear panel to access the blower housing and so the thermal fuse.

Will not start


The problem is likely a blown thermal fuse.Disconnect power then access and bypass the thermal fuse on the blower housing. The blower housing is located on the front left bottom of the dryer cabinet if the dryer has the lint filter on the front or at the rear left bottom if the lint filter is located on the top of the cabinet.

Duet dryer doesn't run. control panel lights up. push on button and all you hear is a click. what do i do?


No dryer function works when the motor cannot run and the common issue is a blown thermal fuse located on the blower housing and wired in series with the motor. There will be no power to the motor when the thermal fuse blows and the motor cannot therefore run. Bypass the thermal fuse and if the motor runs, the thermal use is indeed blown and needs to be replaced. Do not use the dryer with the thermal fuse blown due to fire hazards.

Disconnect power then open the dryer door and remove the lint filter. Remove the screws from the toe panel and remove the panel. Remove the screws securing the lint duct and remove the duct.

The thermal fuse can now be bypassed or replaced if necessary.

Bypass the thermal fuse by disconnecting the wires and taping them together or jumping a wire between them. Once done, plug the dryer in then start it. The thermal fuse is indeed blown and needs to be replaced if the dryer runs. The thermal fuse is part number 3390719. Reassemble the dryer in reverse order of the disassembly steps.

I press start and it won't start. It sounds like a clock ticking


The usual cause of this problem is a blown thermal fuse which is located on the blower housing. It is wired in series with the motor and the dryer will definitely not start if the thermal fuse is blown. Disconnect power to the dryer then remove the rear access panel by removing the screws securing it to the cabinet.

Once the access panel is removed, look for the thermal fuse on the blower housing as shown.

Bypass the thermal fuse by taping together the wires connected to its terminals or jumping a wire between the wires then plug in and start the dryer. The thermal fuse (part number 3392519) is indeed blown and needs to be replaced together with the cycling thermostat (part number 3387134) if the the starts with the thermal fuse bypassed.

Simply unscrew both parts then screw the new parts in place. It's better not to disconnect the wires yet until the new parts are secured then connect the wires to where it should be connected on the newly installed parts. This avoids messing up the wires upon reconnection.

Do not use the dryer with the thermal fuse bypassed to avoid incurring further damage to other components and due to fire hazard reasons.

DRYER STOPPED RUNNING. ALL CONTROLS WORK, BUT WON'T START. HIGH LIMIT SWITCH GONE?


It's either of the thermal fuse on the blower housing or the thermal fuse on the heater enclosure is blown. These thermal fuses are wired in series with the motor and therefore, if any of them is blown will cause the motor not to run and hence the dryer not to work except the controls.

Disconnect power to the dryer prior to servicing to avoid the risk of electric shock.

Open the dryer door and remove the four screws located vertically along the inside lip of the door opening. These screws hold the front panel to the front shroud assembly.

Once the four screws are removed, grasp and press in on the upper edges of the front panel posts then twist it inward to release the clips holding it to the cabinet. Tilt the top of the front panel and move it away from the dryer.

Bypass the thermal fuse on the blower housing by disconnecting the wires and taping them together or connecting a jumper wire between them. Close the door then plug and start the dryer.

The dryer should start and heat up if the blower housing thermal fuse is the culprit. Otherwise, the other thermal fuse on the heater enclosure is blown. Unplug the dryer then bypass the thermal fuse on the heater enclosure in the same way the first is bypassed to confirm it.
4c4483a.jpg

Plug the dryer back then restart it. The dryer should start to confirm that the heater enclosure thermal fuse is blown. Replace the thermal fuse (part number 307473) together with the high-limit thermostat (part number 303396).

Unplug the dryer and unbypass the blower housing thermal fuse then plug it back and restart it. If the dryer fails to restart, replace also the blower housing thermal fuse (part number 33001762) together with the cycling thermostat.

Reinstall the front panel in reverse steps of the removal steps to complete the repair.
