Question about Maytag MDG3706A Gas Dryer

1 Answer

My dryer is not getting hot consistantly. It will warm up then cool off - at times getting warm again. It seems to be doing this on auto-dry as well as timed dry. I changed the cycling thermostat, it got hot at the beginning but seems to be cooling off again. I have checked the other theromstat which checked good with a multi-meter.

This is usually the dryer coils have failed. They tend to fail as they heat up. They are inexpensive and easy to replace. Here is a video on replacing the dryer coils.

Kenmore Elite HE4 Gas Dryer Shuts off prematurely in the Auto Dry cycle and the Timed dry cycle


Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?
Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

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.

I have a Whirlpool Gas Dryer LGR6646BI-12 the clothes feel warm but not hot and they are still damp


The Dryness Level allows adjustment of how damp or dry the clothes are at the end of the cycle.
  1. Make sure the correct Cycle has been selected for the type of fabric being dried.
  2. If the correct cycle is selected and the clothes are still coming out too damp, use the Auto Dry Level button (Kenmore) or Dryness Level button to increase the Dryness level.

  1. If the highest Dryness Level setting was selected and the clothes are still damp, the Customer Focused Drying Mode settings that are built into the machine can be adjusted.
Dryers come from the factory set to Drying Mode 1 (default). Drying Modes 2 and 3, include additional drying time.
Note: This change will affect ALL Auto Dry cycles.
  1. Machine MUST be in Standby mode before beginning. (Standby mode = Plugged in, Power off)

  1. To select drying modes, momentarily press the Auto Dry Level button (Kenmore) or Dryness Level button (Whirlpool) again. The dryer will beep, and the display will flash and show the next drying mode number.
  1. With the door open and the display flashing the desired drying mode number, press the Start button to save the drying mode and exit diagnostics.
  1. Press the Pause/Cancel key at any time to cancel changes and exit from this mode.
Hope this works............

Roper electric dryer. Clothes not drying. Temp ok/timer not?


I would supect a faulty high limit thermostat. This small round device is mounted to a metal plate and attached to the internal ductwork. It can be tested using a multimeter or ohmmeter. Test for continuity. It should have none. Hope this helped and best wishes.

GE Harmony Dryer dries fine one time won't quit sensing the next


The thermostatic fuse is getting hot during the run cycle and then staying open until the dryer cools down completely.

You may fix just by cleaning out the entire dryer. Remove the top cover and vacuum out thoroughly. Replace a torn lint screen and make sure your exhaust conduit is not leaking lint everywhere.

If you can't fix by cleaning, you will have to replace the thermostat which is a $5 part byt a $100 repair.

Dryer warm but not hot, long dry times


some times there are multiple heating elements in there and if one is out it does not get as hot. another simpler place to start would be to make sure your line is clear of debries all the way from dryer to out doors. this is a good idea any way since lint build up can cause the occasional house fire.

My dryer has been taking longer and longer to dry my clothes. Sometimes it takes multiple cycles before the clothes become dry. They seem to be getting warm, but are not drying as quickly as they use to.
