Amana Dryer: intermittent heating

Professional Repair Guide

What is this symptom?

Experiencing intermittent heating in your Amana dryer? This issue leads to clothes starting warm but cooling down unexpectedly during cycles. Common causes include clogged vents, faulty thermostats, or thermal fuses. It's crucial to address this for effective drying and to prevent further damage.

Urgency: Medium

Important Tips for Amana Models

Amana official support emphasizes venting restrictions affecting dry performance; use proper venting size and cleaning.

Possible Causes

Clogged vent or airflow restriction causing overheating shutoff

How to Identify: Long or irregular dry times, lint buildup visible in screen, vent backing up, warm external vent airflow low

Part: Dryer vent/ducting/lint screen

Faulty cycling thermostat

How to Identify: Dryer heats then stops prematurely repeatedly; multimeter testing shows abnormal continuity behaviour

Part: Cycling thermostat

Blown or failing thermal fuse/thermal cutoff

How to Identify: Dryer runs but heating cuts out entirely; continuity test fails; often caused by overheating from airflow issues

Part: Thermal fuse/thermal cutoff

Faulty heating element (electric) or igniter/gas valve coils (gas)

How to Identify: Visual breaks in element, multimeter open circuit; gas dryer igniter weak glow or valve coil failure cases reported on forums

Part: Heating element or gas igniter/valve coils

Loose or intermittent electrical connection

How to Identify: Dryer sometimes wonâ€™t heat until breaker reset; inconsistent voltage at heating circuit

Part: Power connections, outlet wiring

Control/timer contacts worn (electric models)

How to Identify: Intermittency not explained by other components, control parts test may indicate issues

Part: Timer/control board contacts

DIY Solutions

Clean dryer venting and lint screen

Easy 20â€“45 minutes

Tools Needed: vacuum, vent brush

Unplug dryer and detach vent hose
Clean lint screen and use vacuum/brush to remove lint from hose and vent to outside

⚠️ Safety First: Ensure power is disconnected before detaching venting

Test thermostats and thermal fuse for continuity

Moderate 30â€“60 minutes

Tools Needed: multimeter, screwdriver

Disconnect dryer from power (and gas if applicable)
Access internal thermostat and thermal fuse per model manual
Use multimeter to check continuity at room temperature
Replace parts that show no continuity

⚠️ Safety First: Ensure proper multimeter use and power disconnected

Thermal fuse failure

User Suggested Solutions

Clean the lint filter and venting system. Remove the lint filter and clean it thoroughly. Check the vent hose for blockages and clean it out. Ensure the vent is not crushed or kinked.
Replace the heating element. Unplug the dryer, remove the back panel, and locate the heating element. Test it for continuity with a multimeter and replace if defective.
Check and replace the thermal fuse. Unplug the dryer, locate the thermal fuse (usually on the blower housing), test it for continuity, and replace if blown.
