Amana Dryer: Troubleshooting Heating Element vs. Cycling... | appliancefaults.com

Technical Background:

Amana dryers use a cycling thermostat to regulate the temperature inside the dryer drum. The heating element provides the heat, and the thermostat cycles the element on and off to prevent overheating. The MCU (Microcontroller Unit) on the control board monitors sensors and activates relays to control the heating element. 120V AC passes through these components.

Symptoms:

The dryer runs, but there is no heat. Clothes are damp after a full cycle. The dryer may be cycling on and off rapidly.

Possible Causes:

Overheated dryer due to blocked vent
Cycling thermostat failure
Heating element burnout
Faulty wiring to the heating element or thermostat
Defective motor relay
Control board malfunction

Solution:

1

Disconnect the dryer from the 120V AC power outlet and gas supply (if gas). LOTO.
2

Access the heating element and cycling thermostat. Usually located behind a rear access panel or inside the drum housing.
3

Visually inspect the heating element for breaks or burns. Check the cycling thermostat for signs of damage.
4

Using a multimeter, test the heating element for continuity. Should read approximately 9-11 ohms. If open, the element is bad.
5

Test the cycling thermostat for continuity. Should be closed at room temperature. If open, replace the thermostat. Test with an ohm meter. Should be close to 0 ohms when closed.
6

Check the wiring harness for any loose connections or damaged wires using a wiring diagram.
7

If both the heating element and cycling thermostat test good, suspect a control board or motor relay issue. Refer to the service manual for testing procedures.

Safety Warning:

Disconnect the dryer from the power source before attempting any repairs. Dryer circuits operate at 120V AC and can cause serious electrical shock. Lock Out, Tag Out (LOTO) procedure is essential.

Prevention:

Clean the lint filter after every load. Regularly inspect and clean the dryer vent ductwork to ensure proper airflow. Check for kinks or obstructions in the venting.

Expert Tip:

Some Amana dryers have a service mode that allows you to run diagnostic tests and check component functionality. Consult the service manual for the specific steps for your model.

Frequently Asked Questions

•How do I access the heating element and cycling thermostat on my specific Amana dryer model?

Consult the service manual for your specific Amana dryer model. Generally, you'll need to remove a rear access panel or the front panel of the dryer.

•What is the correct ohm reading for the cycling thermostat at room temperature?

The cycling thermostat should have continuity (close to 0 ohms) at room temperature. An open reading indicates a faulty thermostat.

•What tools are needed to complete the replacement?

You will likely need a Phillips head screwdriver, a flathead screwdriver, a 1/4-inch nut driver, a multimeter, and possibly a socket set (5/16-inch or 3/8-inch).
