Prove the vent and power/fuel supply before pricing the dryer. A blocked vent or missing electrical leg can imitate failure; after diagnosis, compare heater, motor, drum and control costs with age, condition and fire-safety upgrades. First, verify full exhaust airflow and correct electrical or gas supply with qualified help where required.

0 of 9 completedEstablish the exact starting state
ReversibleVerify full exhaust airflow and correct electrical or gas supply with qualified help where required.
Separate the fault or decision boundary
ReversibleDistinguish installation/venting from an internal heater, ignition, drive or control fault.
Apply the narrowest correction
ReversibleCompare itemized repair and warranty with a replacement that includes any needed vent, cord or gas-connection work.
Prove the vent and the supply before you price the dryer
ReversibleCheck the airflow at the outside hood, the lint screen, the breaker and, for gas dryers, that the gas valve is open. A blocked vent or a missing leg of the supply can look like a failed dryer.
Separate installation problems from internal faults
ReversibleDecide whether the problem is the vent, the outlet or gas supply, or an internal heater, ignition system, motor or control. An installation fault is usually cheaper to fix and affects any dryer you buy.
Compare the full repair with the full replacement
ReversibleGet an itemized repair quote and warranty, and compare it with a new dryer including any new vent, cord or gas connection. A common rule is to consider replacement when a repair exceeds about half the price of a new dryer and the machine is more than about ten years old.
Rule out the vent and the breakers before pricing anything
ReversibleA blocked vent or a tripped heater circuit reproduces the symptoms of a failed heating element for free.
Treat a heat-pump dryer as a different product, not a like-for-like swap
ReversibleENERGY STAR notes a heat-pump dryer needs no exterior vent, which can matter if your vent run is long or awkward.
Verify before escalating
ReversibleRequire a heated airflow test and safe full-cycle operation after repair or installation.
The numbers
Life expectancy, vent facts and what a new dryer saves
The decision turns on age, on whether the vent is the real fault, and on what a new dryer would save.
- Expected life
- InterNACHI's chart gives a clothes dryer 13 years.
- Vent first
- Whirlpool says the exhaust venting must be cleaned every one to two years and that a dryer that heats but dries slowly most likely has a vent or restricted-airflow problem, so a bad vent can make a healthy dryer look failed.
- Power
- Whirlpool says electric dryers need a 240-volt supply and two 30-amp circuits, one for the motor and one for the heater; a tripped heating circuit gives a turning drum with no heat.
- What a new dryer saves
- ENERGY STAR says a full-size electric certified dryer saves about $210 in energy bills over its life, and a heat-pump dryer uses around 70% less energy than a conventional dryer and needs no dryer vent.
Stop boundary
When this stops being a self-service repair
- !Stop using the dryer for a burning smell, a damaged cord or a persistently blocked vent, and have gas or electrical faults handled by a qualified technician.

Exact questions
Common questions about “Should you repair or replace a clothes dryer?”
How long does a clothes dryer last?+
Commonly around ten to thirteen years. Gas dryers can last a little longer than electric ones.
Is it worth replacing a heating element?+
Often yes, since the part is modest in cost and the repair is common. Check the vent first, since a blocked vent can destroy new parts.
Why is my dryer taking so long to dry?+
A restricted vent is the most common cause. Clean the vent before paying for a repair.
Is it safe to keep an old dryer?+
If it is maintained and the vent is clean, yes. An old dryer with a burning smell or a damaged cord should be replaced or repaired promptly.
Is a $210 saving enough to replace a working dryer?+
No. ENERGY STAR gives about $210 over a certified electric dryer's life, so efficiency alone rarely justifies replacing one that works; a heat-pump model saves more, at about 70% less energy.
My dryer is 13. Is it finished?+
InterNACHI's figure is 13 years, so it is at the typical end of life; a single cheap fix such as a vent clean or a breaker is still worth checking first.
What should I check before paying for a repair?+
The vent, lint screen, outlet or gas supply and breaker. These cause many no-heat and slow-dry problems.
Is a gas dryer repair different?+
Gas ignition parts and safety valves need a professional. Do not work on gas parts yourself.
