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.

Dryer works except there is no heat. Gas line is open and looks fine, what could be the problem?


Hello there and thank you for choosing fixya
This is a fairly common problem with gas dryers there are several components that need to be checked thoroughly i will list them here below ok?
Quick Gas Dryer Tips:

Problem -
Gas flame comes on first few times then quits and igniter keeps cycling on and off but never lets the gas go.
Answer ( most common ) -
Replace the coils on the Gas Valve.

Problem -
No flame, no igniter glowing at all,
Answer ( most common ) -
Inspect igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter when dryer should be calling for heat.
On the back of the dryer near the fan blower housing is a thermal fuse, if this opens up ( no continuity ) the gas burner often quits but the motor will still run. If the thermal fuse is open/bad, always clean, change, adjust the venting system and vent hood first and clean out the dryers air ducts. Sometimes it is a good idea to replace the operating thermostat at the same time.
Thermal fuse parts help link...on blower housing cover, can not be re-set, must be replaced if is open (no continuity between pins).

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

The dryer isn't getting hot, clothes aren't drying. It's a gas dryer, so I'm not sure why it won't get hot


remove the bottom panel and start the dryer,if the ignitor isn't glowing orange or red then you could have a bad thermal fuse located on the blower wheel housing,a bad ignitor or a bad sensor located on the left side of the ignitor and on the outside of the burner tube,you'll need a meter to check the parts out,unplug the dryer,you need to pull at least one wire off the part you're going to check,the part will give you a reading or no reading it's that simple,if you get a reading it's good,if it stays on 1 and nothing else it's bad.if the ignitor is glowing then you have bad gas coils,bad gas valve or the ignitor could still be bad but most of the time if it's glowing it's good.if the dryer hasn't been cleaned in a long time check the thermal fuse first,pull out the lint filter,then remove the duct that the filter slides into and you'll see the thermal fuse on the right hand side of the blower wheel,it will be a 3392519 or a 3390719,these are the common fuses,if that's good read out the other parts,also if the fuse is bad you need to clean out the lint filter duct,vac out the bottom part of the dryer,then remove the vent line and blow it out if it's long,i use a leaf blower and it cleans the line out,go outside first and make sure the vent is clear so when you blow out the line nothing is blocking the lint from blowing outside,i've seen bird nests blow out of the line.clean it out once a year so you don't have a fire,the fuse won't blow again and your clothes will dry on time,let me know how you make out

Dryer fails to heat up. I tried replacing the glow bar with no success.


Hi

If your dryer is not heating, then check if the power cord is plugged into the wall. It may be loose or disconnected. Inspect the fuses and circuit breakers they may have burned out or tripped. Usually, dryer will still tumble but not create heat if a fuse or a circuit breaker is not working. Now, check whether the heating element in your gas dryer is burned out by using an ohm meter to check for continuity. If the continuity is not there then you would need to replace the element. After checking the element, check out the thermal fuse to see if it's burned out. The thermal fuse is attached to the exhaust duct on the back panel of the gas dryer. It's usually surrounded by a black resin material situated in a housing made of white plastic. If the fuse looks like it's blown, then it needs to be replaced.
Now, check the igniter, there is a plastic connector attaching the igniter to the burner. Disconnect this and place the probes onto the two contacts of the igniter. The meter should read under 100 Ohms of resistance. If the reading is above 100 ohms then igniter is bad. If the igniter passes the test then you need to test continuity on the flame sensor. You should have continuity between the two contacts. If not, then you need to replace the flame sensor. The sensors are usually located close by the igniter so are easily visible. Hope this helps...

Kenmore gas dryer no heat . 90 series model 110.70902990 have power, did vacum lint from access panel@ FRONT


unplug the dryer,remove the lint filter,take off the bottom panel and remove the duct that the lint filter slides into,clean the duct out,while you have the duct off on top and to the right of the blower wheel housing you'll see a 3390719 thermal fuse,remove one of the wires and check it with your meter to see if it's good,most of the time if the dryer hasn't been cleaned out the fuse will blow,the dryer runs to hot and the fuse is a safety so you don't have a fire and so the dryer doesn't run hotter than it should. vac out the inside of dryer and if you have a shop vac it blows on the other side,blow off the motor and blow the lint from the back forwards so you don't have to remove the drum,next you have to clean out the vent line,if it's a long run from the back of dryer to the outside flapper i use a leaf blower to blow out the line,you should clean the dryer once a year,if the fuse is good you need to check with your meter the ignitor,the sensor and the gas coils to see what's bad,if you need anymore help let me know,good luck,when you're reading anything out with the meter make sure you remove at least one of the wires or you'll get a false reading

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

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
