Maytag Dryer: blowing thermal fuse

Professional Repair Guide

What is this symptom?

If your Maytag dryer keeps blowing the thermal fuse, it indicates an overheating issue or unsafe temperature detection, interrupting its normal operation. This common problem can stem from restricted airflow due to blocked vents, a faulty thermal fuse, or issues with the thermostat or heating elements. Addressing these causes promptly is essential to ensure your dryer operates safely and efficiently.

Urgency: Medium

Important Tips for Maytag Models

No unique brand-specific documented thermal fuse issues beyond general dryer causes identified; Maytag uses typical thermal fuse safety devices

Possible Causes

Restricted airflow/blocked vent system

How to Identify: Dryer overheats, runs but no heat or stops mid-cycle; visible lint buildup in vent/duct; poor drying performance

Part: Dryer exhaust vent/duct, lint filter

Faulty or weak thermal fuse (own part failure)

How to Identify: Thermal fuse tests open on multimeter with no continuity, even after addressing airflow issues

Part: Thermal fuse

Faulty thermostat or cycling thermostat

How to Identify: Dryer overheats even with clear airflow; high heat beyond normal cycling; thermal fuse repeatedly blows

Part: Thermostat/temperature sensor

Faulty heating element or internal short

How to Identify: Heating element may heat excessively or unevenly; check resistance and insulation; draws excessive current causing overheating

Part: Heating element

Control board/relay stuck on heating circuit

How to Identify: Dryer continuously sends power to heating element even during cool down; thermal fuse blows then

Part: Control board/relay

Estimated Cost: $150 - $400

When to Call a Professional

If internal electrical components such as heating element or thermostat need testing/replacement

If control board issues suspected

If you are uncomfortable working with electrical components

Preventive Maintenance

Clean lint filter: Airflow restriction leading to overheating
Frequency: After every use
Inspect and clean vent system: Clogs that cause high temperature and fuse blowing
Frequency: Annually or when drying slows
