My Maytag gas dryer is not heating correctly. It gets warm, but takes several cycles to dry even small loads.

That sounds to me like you need to replace the coils. They get intermittent with age. Work some then quit take a long time to cool down and work a little more when going bad.

Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

you need to either dismantle the venting pipe ductwork inside the dryer and get inside the duct and loosen all dried on lint which is holding moisture in,otherwise the cycling switch for the flame is cutting out tooooo sooooon and your not drying the load properly per selected load setting

how do i set this dryer to dry my clothes??? what is the right setting?? should i use the time dry setting or the more dry/less dry setting?? Clothes never dry???????????????????????????????????????????????????????

If you have'nt done it yet, my first suggestion would be to have the vent on the dryer (inside the dryer all the way to the fan chamber) and the dryer vent pipe to the outside thoroughly cleaned.
That is leading cause for dryers not drying completely.
Also, has the dryer always been a bit slow to dry cloths? If so, try leaving a window open the next time and see if it makes a difference. Some houses are sealed so tight, the dryer can't get enough air. A typical dryer will use up to 200 cu/ft of air per minute when drying. If there is not sufficient air, the cloths take longer to dry.
Good luck, let me know.
Regards,

Could be 2 things... either your heat source is out of repair or your vent is blocked. Since you say it only gets warm I'll assume the problem is with the gas coils inside the unit. These parts are replaceable

first, check your exhaust, you have to make sure there is no buildup at all inside it. this is the most common problem to cause this. if lint gets backed up, there is a sensor that shuts down the heating element after only a few seconds. hope this helps

the vent that takes the air from the dryer out of the house is clogged. not the part right behind the dryer but from where it goes into the wall to where it leaves the house needs to be cleaned. when the air cant leave the dryer at normal speed it takes for ever to dry a load of clothes

Mj, 90% of the time long dry times are caused by a pinched or clogged vent. Other things that could be causing this are: cycling thermostat trips too soon, if your dryer is a gas model, weak gas valve coils, drive motor centrifugal switch not allowing voltage to the gas valve or heating element. Check the harness to the motor to make sure it is on tight. Catriver...post back.
