Flash, did you check the thermal fuse in the back? On a gas dryer the drum will still turn if it's blown. check out the picture and post back.

SOURCE: We have a Kenmore gas dryer that won't heat. We

Hello Friend, Your problem is very simple to fix. You're dryer needs a thermal fuse and or gas valve coils, and maybe an igniter all three are very simple and affordable to replace. To replace the thermal fuse just remove back cover of dryer and look down where the air blows out. Now, just to the left where all the wires are you will see a white plastic part with two wires plugged into it. This part is called a thermal fuse. Just remove these wires and replace the thermal fuse. Now, if this don't solve the problem you will need a gas valve coil kit. To replace coils just remove front of dryer body and look below drum you will see the gas valve. The valve coils are located on top of valve (two little round black cylinders). It's simple, just remove the two screws from the little metal bracket that holds them down, unplug the wires from them and just lift them straight up off of the valve. Take notice that one has 3 wires and one has 2 wires. Just replace with new coils and plug wires back in and re-fasten metal bracket. Your dryer will run like new, if it doesn't then you will need to check the igniter. The igniter is attached to the end of the burner assymbly by one screw and a simple two wire plug. Inspect for breakage, and replace if needed. Happy to help, Tim. And please don't forget to give me your rating for my help.

SOURCE: My dryer doesn't produce heat. the coil ignites

It's likely one of the coils is opening a break in the coil as the coil heats up. This coil will shrink when cool and be able to run again. In your machine, it appears Amana doesn't sell the coils as a separate item and the whole valve needs to be replaced. The part number is Y504091.

Disconnect power and turn off gas before working on this dryer. Working on gas dryers is not recommended for people who are not professionals.

Service on gas appliances should be undertaken by professionals only due to the danger of gas leakage which can cause fires or death by asphyxiation.

At front, remove 2 screws near floor at the bottom of the lower front panel. Pull bottom of panel toward you and down. The gas valve should now be accessible on the left. Take care not to touch or hit the ignitor or you will be replacing it also. It is VERY brittle.


Reverse process to re-assemble.

SOURCE: Kenmore gas dryer no heat

The thermal fuse is easy to test. Just check continuity using a multimeter or ohmmeter. A lack of continuity means a blown thermal fuse.
The coils are difficult to test. You can use a multimeter or ohmmeter and check for continuity, but the problem is that a coil may be sticking open only after heating up, so you can see the difficulty this would present. If a coil is suspected of being faulty, it is best to replace both (all) at the same time. These coils are what permit the gas valves to open and they can cause a no light or a cycling condition. Really sorry for your trouble and I hope this helped. Best wishes.

Wont heat


do you hear 3 clicks when you start it up,these clicks are the gas valves opening to supply the unit with gas for operation,if no clicks are heard it can be the thermal fuse is open,if only 1 or 2 clicks check continuity of the main and secondary gas valve coils as they can open up or get weak from heat during operation,usually just replace both coils on the gas valve as they are inexpensive one has 3 connections and the other has only 2 connections,but first bypass the thermal fuse with a jumper wire (for testing only) then replace the gas valve coils next,unplug both coil connections then remove 2 screws holding the valves to the valve and replace and reverse dis-assembly procedure

Model LGR8620pw0 dried 2 loads of cothes, third load no heat. Tried the dryer next morning and it heated up.


This is likely a coil on the gas valve on its way out symptoms will often be very erratic. Replace the coils if symptoms persist.

Gas drier Whirlpool LGR5634LQ0 drum turns, no heat. Turn off and restart, heats for a while then no heat for drying. Lint is clear, etc... Gas valve is in on position. Not sure what to do next. Check...


most gas dryers will have a problem with the 2 coils on top of the valve.
when these coils are weak or going bad, it will heat for a short while then no heat at all.
if you let the unit set for an hour or 2, it will heat again for a short peroid.
the coils are easy to replace, but do get both of them.

Kenmore gas dryer 110.97278100 won't heat


there's a thermal fuse that usually is the problem. when you push the start button; listen for 2 clicks. The motor centrifugal switch & than the coil on your valve. If you only hear 1 click, replace t-fuse. if you hear 2 clicks than ck for problems in the flate sensor,ignitor,gas valve

Hi

First check and see if you have 110 volts coming to the gas valve at this type of a connector. If you have voltage, then unplug the dryer and check the parts I have pointed to. Some dryers have 3 coils instead of the 2 shown here. If you do not have voltage coming to the burner, then you will need to check the timer contacts that feed the gas burner, hi limit thermostat, operating thermostats, the safety switch on the motor, and any other point that you can see on your wiring diagram picture that feeds voltage to the burner. The coils on the gas valve are very bad for working once or twice and then quitting. If you find an open circuit on one of the gas coils, replace them all = less problems later on. If the glow coil does not work (get red), check it with an ohm meter for continuity. The next thing to check if the glow coil does not come on would be the radiant sensor. Inspect the igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter wire plug when dryer should be calling for heat. Sometimes the ( older style ) igniter is separate from the holder and the holder can no longer hold the igniter tight enough and the two parts burn/arc where they touch each other = new igniter and holder ( some manufactures have new kits to replace these older style parts ).
If the igniter gets red and stays red, or you hear a click and it goes off, then a minute later its gets red again then possibly have a bad set of coil valves. If the igniter gets red and stays red constantly then it’s the flame switch that is bad and maybe welded closed.

Please do rate the solution and revert for further assistance.


Thanks

Kenmore series 80 gas dryer will not heat up


Hi. this dryer has a set of coils that sit on top of the actual gas valve assembly. these coils activate the main and secondary gas valves and if the coil assembly is malfunctioning or, the wires and clips are corroded, the coils will not activate the gas valves to open and close. this malfunction will affect the heating process within this dryer unit.

I recommend inspecting the dryer coil assembly. use a mulitimeter to test for Resistance. you should get a reading of some type of current flow through the wires and, if this is the case, the coils are bad and they will need to be replaced.

This test is actually not needed. the non existing heat is a red flag on its own and, it greatly confirms a major failure within the coil assembly. replacing the coils will fix your dryer.

PLease rate and god bless:)

Dryer working but no heat


If it does not heat , and you already checked the burner and the ignitor, then it is probably the thermal fuse at the back of the appliance.

See the following suggestions from Repairclinic:

No heat If your dryer doesn't heat, check these:

Igniter
Gas valve coils
Thermal fuse
Igniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too.

The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one.

Gas valve coils Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.

Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

Gas dryer is not heating up


Could be a bad set of burner coils. Does the glow come on for a bit then goes out. And after a bit does same?
Probably bad coils. If you were able to change ignitor, you can do the coils. Unplug first! The coils are the 2 black cylinder shaped devices on burner. They are held on with a bracket that has 2 phillips screws. You can probably take them to your parts house and they can ohm them out for you. Make sure to write down their position before removing them.
