Amana gas dryer only heats first 20 minutes

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.

Hi and welcome to FixYa. I am Kelly.

You did not mention if the dryer was even warm to the touch during operation.

The generic service manual can be found here:

http://www.servicematters.com/maytag_library/docs/RS3200007R0.pdf

I would follow the troubleshooting process in step 9 of page 21.

To gain access to the unit you will need to remove the service access panel Pg 28 of manual

Gas burner circuits steps are on page 32

A little about heat control circuits. They are series circuits and any one of the following can prevent the dryer from heating.

1. Motor switch
2. heat control
3. cycle thermostat
4. high limit thermostat
5. thermistor
6. heating element

in addition to the above

For gas burners

1. Gas valve
2. Gas safety valve
3. Ignitor
4. Flame sensor

Most dryers have at least 5 of the 6 components listed in the first set of components above. The high limit thermostat is replaced by the thermistor in newer models. Thermistors are a one time fail item and if it has opened it must be replaced.

The warranty for this dryer is as follows:

1 year full coverage

Limited Warranty

After one year from the date of original retail purchase, Amana will provide a replacement part, f.o.b. Amana, Iowa, as listed below, for any part that fails due to a defect in materials or workmanship. The owner will be responsible for paying all other costs including labor, mileage, and transportation.

Second through Third Year
Amana will provide any part.

Third through Fifth Year
Amana will provide the drive motor or timer.

Third through Tenth Year
Amana will provide the cabinet assembly should the part rust through.

Lifetime
Amana will provide the Stainless Steel inner drum if so equipped.

Thanks for using FixYa.

Remove the front panel and check the blower wheel on the motor. If it turns freely on the motor shaft replace it.

I was experiencing a similar problem. I just repaired mine yesterday, with the help of this web site. Remove the front bottom panel. The are two screws located on the bottom of the panel. They are there, just slightly hidden. Turn on dryer to heat. Look inside where the panel was. Wait a minute or two and you will see the igniter glow. After a minute or so you might hear a click and the gas valve will open to start flame. After a while flame will go out until it cycles again. If your igniter glows and you hear the rattling noise and then the igniter glow goes out and you have no flame, it might be your solenoid coils are bad. These are the two black round things located on top of the gas valve. Make sure your gas dryer is unplugged. There is a wire clip attached to each solenoid. Unplug them. I needed to pry them off carefully with a flat screwdriver. There is a metal bracket holding those two solenoids in. There are two screws that you will need to remove the bracket. Use a flashlight to see them. Slide them up and off the gas valve. One is a 2 prong and one is a 3 prong. I bought a new set for 26.75. Put the new ones back the same way as you took them off. The is little nips on the top of the solenoid that line back up with the holes of the top bracket when reassembling them. Plug your machine back in and turn on and watch to see if the ignitor glows again and watch for the flame. Put panel back on and enjoy dry hot clothes again. GOOD LUCK

Replace the coils (2) on the burner valve .

It sounds like the thermostats are going, unplug machine and remove the back panel, which is a bulgy bit on the back (not the main panel) you will find two thermostats with four wires above the heater. replace these.
