90% of all gas dryers lighting intermittently is resolved with new coil packs on the gas valve. The coils are replacable fairly easily and inexpensive.

If you hear the valve clicking but no gas the valve is bad.when the burner lights theres a probe that senses that it is lit and sends a microvoltage back to the controller to tell its lit.check to make sure all ground wires are grounded to a clean metal surface.

    to eliminate the gas valve as being faulty take an ohm reading on the coil.then take a voltage reading when it fires.if you have the correct standing voltage on the coil and no gas --its the valve.

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.

How do I test the ignitor?


unplug the dryer,then unplug the ignitor and with a meter read it out,is it glowing?if not it could be the ignitor or the sensor or the thermal fuse located on the blower wheel housing,if the filter is on top remove the back panel and you'll find the fuse there,it's white and it's a 3392519,pull one wire off and check it with a meter,if it's bad you need to clean out the duct that the lint filter slides into,and clean out the vent line or the fuse will pop again,if the filter is inside then the fuse is in the front of dryer,take off the bottom panel,pull out the filter,remove the duct that the filter slides into and to the right top side of the blower wheel housing you'll see the thermal fuse on the left side,it might not be the 3392519 it could be a 3390719 but you need to send the model number to look it up,if the ignitor is glowing then you have bad gas coils or a bad gas valve.hope this helps let me know what you find

Kenmore 110 74842400 runs but no heat ignitor does not glow ,I haven't checked to see if ignitor is getting power If it is am I looking at a heater relay?


check the thermal fuse 3392519 located on the blower wheel housing,if the dryer hasn't had a clean out and lint is everywhere most likely it will be the fuse,check it with a meter,pull one of the wires off and read it out,your model number shows the filter on top so unplug the dryer,pull out the filter,take out the two screws on top where you pulled out the filter,take the vent line off and take off the back panel,on the left you'll see the duct that the filter slides into,take out the four screws holding it in and clean the duct out,when you put it back on look to the right and down around 4 inches up off the floor and you'll see the white thermal fuse,read it out,if that's good then you gotta make sure you're getting power to the ignitor,and read out the ignitor,the sensor and the gas coils,hope this helps,you don't have a heater relay on this model

remove the bottom panel with a screw driver,there are two clips holding it on,run the screw driver across the top and you'll fell them,just push in on the screw driver aand they'll release one side at a time,unplug the dryer,take out the lint filter and remove the duct that the filter slides into,clean the duct out while you have it off and vac out the inside of dryer,also clean out the vent line,you shold do this at least once a year so you don't have a fire,now check the thermal fuse part 3390719 located on the top right side of the blower wheel housing where you took the duct off of,pull one of the wires off and read out the fuse with a meter,usually this will pop if you need a clean out on the dryer,if that's good,you'll have to read out the ignitor,the sensor and the gas coils,if the ignitor comes on when you first start the dryer and stops when the dryer heats up change out the gas coils,if they are bad they usually fail when they heat up,hope this helps you out

Kenmore Elite Sensor Smart Gas Dryer - no hot air


unplug the dryer,if you haven't cleaned out the dryer check the thermal fuse located on top of the blower wheel housing,remove bottom panel,then remove lint filter,now remove the duct that the lint filter slides down into,now you'll be able to check the thermal fuse located on the top right side of the blower wheel housing,there's also a thermister there too,the fuse is the one on the left,part number 3392519 or 3390719,remove one of the wires and read it out with your meter.also while your in there vac out the inside of dryer,if you have a shop vac put it on blow and blow off all the lint that's built up on the motor and you can also blow the lint that's in the back of dryer forwards so you won't have to pull the drum,if you have a long run on the vent line from the wall to the outside blow it out with a leaf blower,if there is any blocks in the vent line,the duct or lint inside the dryer you could have a fire so this should be done every year,now if the fuse is good you gonna have to read out the ignitor,the sensor and the gas coils,if you have parcial heat it's definetly the gas coils,when they heat up they stop working when they're bad,if you need anything else let me know,so check the thermal fuse first,then the ignitor,sensor and coils,if they are good check to see if power is coming down to fuse and ignitor,you have a computer board on this dryer but most of the time it's the fuse and a dryer clean out

Dryer runs but won't heat/dry clothes and doesn't stop running


if it's on auto the timer will not advance without heat,is your dryer gas or electric?next time send model number,check the thermal fuse on top of the blower wheel housing located under the lint filter,also while your there take off and clean out all the lint in the blower wheel duct,most of the time no air movement is what usually causes thermal fuse to pop,if that's ok start reading out the heater if it's electric or if it has even heat board and relays you'll have to check them also,if it's gas read out the ignitor, sensor and gas coils,you gotta send model number and a little more info next time

Our kenmore # 110-728220 turns but no heat. replaced ignitor still no heat


Check the following areas to combat this issue. the most common problem spot will be a blown Thermal fuse.


1. Gas valve coils
igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. igniter
igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.

Dryer will not start


yes there is a thermal fuse mounted on the blower housing duct. it is about 1 inch in length and white with 2 wires on it. if the dryer overheats for any reason this will fail.
make sure the lint filter is cleaned every load and the exhaust vent is clean and not pinched off behind the unit. venting is the most common problem to cause these to fail.
you can get to this by removing the lower access panel and then the blower duct. that will give you easy sight of the thermal and makes it easy to replace.
by the way unplug the unit first!!
