This free dryer symptom checker asks one or two questions about what your dryer is doing, then lists the likely causes, the safe checks to try first and when to call a technician. It covers no heat, slow drying, no start, noise, smells, early stops and a tripping breaker. If you smell gas, it tells you to leave the house.
Key takeaways
- Pick the main problem, answer a question or two, and get the likely causes.
- Every result lists safe free checks first, and when to call.
- A gas smell gets the emergency steps immediately: leave and call 911 and Atmos Energy.
- It runs in your browser and sends nothing anywhere.

How does the dryer symptom checker work?
You choose the main problem, answer one or two follow-up questions, and the checker lists the likely causes in order of how common they are, the safe checks to try first and when to call a technician. It is built from the same guides on this site, and each result links to the matching one for more detail.

Can the symptom checker diagnose my dryer?
No. It narrows down the likely causes from what you describe, and it points to safe checks, but it cannot test a part. A technician confirms the fault with a meter and gives you the price in writing. Treat the result as a starting point, and stop and call if anything involves gas, burning or the 240-volt side.
What it does not cover
- Ventless condenser and heat pump dryers, which work differently
- Faults that need testing with a meter
- Anything involving gas piping or house wiring
- Your dryer’s own error codes: check your manual for those
What if my symptom is not on the list?
Browse the dryer problems page, which covers more symptoms, or try the troubleshooting FAQ. If the symptom is a gas smell, a burning smell, smoke or a hot outlet, stop and treat it as a safety issue before anything else.

Frequently asked questions
Does the checker store my answers?
No. It runs in your browser, and nothing you choose is sent to any server or stored. Reloading the page clears it.
What if I answer a question wrong?
Use the Back button to change an answer, or Start over. Each question is a guide, and different answers lead to different checks.
Why does a gas smell show an emergency result?
Because a gas leak is the one symptom where acting immediately matters more than diagnosing. The result tells you to leave the house and call 911 and Atmos Energy at 866.322.8667 from outside.
Are the causes listed in order?
Yes, most common first, based on the usual patterns for dryers. Your dryer can still be the exception, so a technician’s test is the only sure answer.
Is it safe to do the checks listed?
They are chosen to be safe and free: breaker, plug, door, lint screen, vent and wiping a sensor with the dryer unplugged. Anything inside the cabinet, on the 240-volt side or with gas is listed under when to call.
