When dryer heats too slow, that means that there is a problem either with the heating element, the thermostat, or the vent.

See the following suggeations from Repairclinic:

Drying is too slow It normally takes about 45 minutes for a dryer to dry a full load. If your dryer is taking more than an hour, check these.

Vent
Heating element
Internal ductwork
Cycling thermostat
Vent Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance.

Heating element Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace it.

Internal ductwork Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum, contact a qualified appliance repair technician.

Cycling thermostat Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.

Sg7800 maytag dryer stopped giving heat


Sounds like burner not igniting. On front of dryer in the lower right there should be a gas valve/burner access panel. Usually you just have to pry out at bottom of panel & swing out and up to remove. This gives you access to valve coils and igniter. With panel removed set timer for heated dry and start dryer, observing first the igniter which should glow bright orange-red, then after a couple seconds you should hear a "Click" which is gas valve opening and a blue flame ignites for heat. If no glow is seen after a few seconds or at least a minute, igniter is bad, if it does glow and no click is heard from the gas valve, the coils (electro magnets) on the valve are bad, or the "Flame present" sensor is bad. Chances are it's either the coils or igniter.Try this on all heat settings, if you get heat at only one setting it might be in timer contacts, but not common. Again you can repair/replace both the igniter (usually just plugs into a receptical) and the coils (2 donut looking objects on the gas valve, replace both.) Access door may be on back if not on front, but normally their on lower right of front.

The dryer has no heat when turned on.


Check your coils & igniter. Access door usually located in lower right front of dryer. Remove (pry up & out from bottom of panel, if no screws, exposing burner assembly. Set dryer for heated dry and start, you should see the igniter glow bright orange (give it at least a minute) followed by a CLICK sound,(again, a few seconds) this is the coils opening the gas valve, followed by a blue flame for heat. If no glow, replace igniter. If igniter glows bright and no click, replace the coils.

HI. This will essentially be an issue that concerns the gas valve coils. With that said, I will post below a complete burner assembly procedure that will help you isolate the culprit. I'm sure that the coils will fail the test, but to be safe, follow the procedure to confirm.

Gas valve/Burner testing procedure:

On the gas valve are one or two coils (solenoids) used to open and close the valve to control the flow of gas. If a coil fails, gas will not flow and the dryer will have no heat.

The easiest way to diagnose a problem in the burner assembly is to observe the burner operation. Remove the small access panel at the bottom, front of the dryer, select a high temperature setting and start the appliance. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow. Next you should hear the click of the gas valve coil and a flame should ignite. The flame should be mostly blue and it should remain on for a minute or more.

If the ignitor glows for several seconds (up to 15 seconds) and then goes out, the problem is probably the coils (solenoids). If the ignitor glows and stays on, then the problem is usually the flame sensor. If it ignites and then quickly goes out, it is most likely a problem with inadequate air flow.Test the coil for resistance using a multimeter. Set the multimeter to the ohms setting X10. Place a probe on each terminal. The multimeter should change from a reading of infinity to roughly 1300 ohms (+/- 150 ohms) when the probes touch the terminals. If the reading is infinity or substantially different from 1300 ohms, the solenoid should be replaced.

Click Here to access a exploded diagram of the burner assembly. The affected coils will be labeled number 15 and 10. The actual coil and valve assembly will be labeled number 11 and the burner will be labeled number 9

The exhaust blower starts for about 15 seconds then shuts off. several minutes later, the same thing happens - over and over


goodman furnance the exhaust fan starts, igniter glows hot, all burners lite up & will burn for about a minute and shuts down . I think it senses the room blower does not start so it shuts down.

Kenmore gas dryer mod.110-73942. burner comes on as normal. After 5-10 minutes running Cycles off, igniter ( new) glows but no burner ign. Also replaced the sensor adjacent the igniter.


The gas valve coil is bad. When the ignitor is glowing the gas valve should open and allow gas in to be ignited. Change the gas valve.

Dryer's flame cycles but will not burn


Check the following to address this issue..


1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.

After a few heating cycles the burner does not ignite


The problem you are describing is usually associated with a bad gas valve coil. The dryer runs normally until it gets hot, then starts making a strange clicking noise. After it cools down, the dryer runs normally again. The gas valve coils (there are two of them) usually run about $20 a piece. I recommend replacing both of them at the same time just to be sure. I hope this helps.
