Amana Dryer Blowing Cold Air: Troubleshooting Guide -... | appliancefaults.com

Technical Background:

In a timed dry cycle, the timer signals the heating element to energize. Voltage flows through the thermal fuse, thermostat(s), and then to the heating element. The MCU may also be involved monitoring temperature and safety.

Symptoms:

The Amana dryer runs, and the drum spins, but the air coming out is cold even on the timed dry setting. Clothes are not drying.

Possible Causes:

Faulty heating element
Defective thermal fuse
Malfunctioning thermostat
Blocked vent
Failed dryer timer or control board

Solution:

1

Unplug the dryer from the outlet. This is crucial for safety.
2

Access the rear of the dryer by removing the back panel using a 1/4-inch nut driver.
3

Locate the heating element housing. Disconnect the two wires connected to the heating element.
4

Using a multimeter set to ohms, test the heating element for continuity. A typical reading should be around 9-13 ohms. An open circuit (infinity) indicates a failed heating element and requires replacement.
5

Locate the thermal fuse, usually near the blower housing. Test it for continuity. It should read close to 0 ohms. If it reads open, replace it.
6

Check the thermostat(s) (often a high-limit thermostat) near the heating element. At room temperature, they should have continuity. If open, replace.
7

Thoroughly inspect the dryer vent for blockages. Use a vent cleaning brush. Ensure the vent hose is not kinked or crushed.

Safety Warning:

Disconnect power to the dryer before any repairs. Lock Out/Tag Out (LOTO) the breaker to prevent accidental energizing. High voltage is present in the dryer. Wear appropriate safety gear.

Prevention:

Clean the lint trap after every load. Inspect and clean the dryer vent at least annually to prevent lint buildup.

Expert Tip:

Some Amana dryers have a diagnostic mode. Check the tech sheet located inside the dryer cabinet (usually behind the front panel) for the specific sequence to enter service mode and retrieve error codes.

Frequently Asked Questions

•What is the correct ohm reading for a working Amana dryer heating element?

A typical Amana dryer heating element should read between 9 and 13 ohms.

•Where can I find the tech sheet for my specific Amana dryer model?

The tech sheet is usually located inside the dryer cabinet, often behind the front panel or attached to the inside of the back panel. Check both locations.

•Can a clogged lint screen cause the dryer to blow cold air?

Yes, a severely clogged lint screen restricts airflow, causing the thermal fuse to blow, which cuts off power to the heating element, resulting in cold air.
