    Dear Fixya Team, Your prompt reply is most appreciated.

    The heat was consistent but very very low. I tried all heat temperature settings on the dial including the highest heat setting. I checked the chute but found no blockage, then removed the chute connection from the bottom of the dryer, again there appeared to be no blockage. The link trap was clean and then I ran the heat setting again without the chute attached. Once more the heat was very slight there but not enough to dry the clothes. An additional thought which may or may not have any some bearing on the problem: The dryer is free standing and not touching any other appliance or part in the basement including the washing machine, so there was no question that heat was generating toward the dryer. The average outside temperature right now in Michigan is about 68 degrees. The dryer is on the north side of the basement and no sunlight is directed toward that side of the house. I tried to just dry two light small articles of clothing on the higher heat setting and felt very little heat inside the dryer, but all it did was tumble the clothing around for about 30 minutes. It was not as damp but not even dry, maybe most likely because the tumbler was airing it out. If it was the thermostat that had gone out, would not that be either working or not working, heat or no heat?

    Thankyou so much for your suggestions, Caroline.

    Does the dryer maintain some heat throughout the entire cycle, or just at first?
    If the heat only works for a short time and then stops heating completely,it may be the gas valve coils.
    If the heat is just cycling off too soon, you may have obstructed ducting, which will cause the thermostat or thermistor to cycle off quickly. Check the outside airflow, and make sure that is clear. If airflow is good, the heat comes on properly the entire cycle, and you still feel the temp is too low, you may want to replace the thermostat (or thermistor, depending on which one your model has, the thermistor takes the place of the operating thermostat on newer models)

Just a quick thought...make sure that your gas shut off valve is ALL the way open.
In answer to the thermostat question, if the thermostat has completely failed, (open circuit) you're correct, there would be no heat at all. The thermostat contains a tiny heater, controlled by the heat select switch, for instance, if you set the switch to "low heat" the thermostat heater will turn on, applying heat to the thermostat, which means when the main heat turns on, the thermostat will cycle off quicker, because although the air temp may be, say...120F, the thermostat is at 160F. So, that being the case, you could possibly have a problem with the temp switch applying voltage to the thermostat heater constantly, and excessively. Or, the thermostat could just be cycling too quickly. This could be tough to pinpoint exactly without taking some voltage readings with the machine running....one way to check the switch is to remove the two small wires from the thermostat, (leave the larger wires on) and see if it heats properly, that would mean the switch is bad. Please remember to unplug and verify that there is no voltage with a meter before messing with any wires. Hope this helps narrow it down....

10 year old Kenmore dryer Series 80 suddenly has stopped producing heat. Vent is clean. What else can I try?


On a gas model dryer those coils seem to die when heated when they have a little age on em. So if the ignitor works and the dryer does a little bit of heating then fails and it is gas then those coils are the problem. On an electric model the element will get brittle with age and die but if your dryer is suffering from air restrictions it may have had a limit trip on it.

Maytag gas dryer heats up for a little while then heat shuts down. Also makes a squeeking sound when turning.


is it a maytag or a whirlpool dryer. you are saying it is a maytag but it has a whirlpool number. if it is a whirlpool then you will need to chage the rollers and idler pully. also if it is heating up, I would check to see if your vent is clear. let me know if this helps

Kenmore 80 series gas dryer has not heat


most of these dryers have a little plastic plug on the front, left side. pop that plug out and look inside after turning it on. you should see a red glow. if not, then your ignitor has broken. if you see a glow, then the problem is probably one of the two little coils on the gas valve. these coils will sense if there is something to light the gas [the red glow] and open the valve - if the coils are bad, they won't open the valve

Whirlpool dryer has very little heat


Sounds like your not getting enough gas supply,there is a regulater that controls the flow of gas they can get carbon build-up and restrict the gas.You need to turn off your gas supply and unplug it,remove the regulator and clean the lines,or replace the part.

Hope this helped.Let me know by rating me or

Kenmore 90 series gas dryer, NO HEAT!!!


Hi, if you get no glow on the ignitor and you have voltage its the little white two terminal fuse on the exhaust side that has no continuity on the series 80 it has 2 blue wires, these complete the circuit for both gas valves and the ignitor. If you have an ohm meter it you will find it rite away. Hope this helps.
