Direct answer
For the Maytag MED7230 electric dryer, a restricted exhaust is the first safety and performance check when drying time increases. First, clean the lint screen and compare airflow at the exterior hood.
What this covers
- Maytag MED7230 electric dryer (MED7230H*)
- Maytag dryer; confirm electric/gas model and complete suffix.
- The specific fault this record addresses: takes too long to dry clothes
What it does not cover
- ×The same symptom on a different Maytag product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The exterior exhaust vent is partially restricted
What separates it Drying time has crept up gradually over weeks or months, the outside of the dryer or the door feels warmer than it used to, and the exterior vent hood flap barely moves during operation compared to when the dryer was new.
How to confirm Disconnect the vent at the back of the dryer briefly and feel for strong airflow directly from the dryer — if that airflow is strong but weak at the exterior hood, the restriction is in the ductwork between the two points, not the dryer.
- 2
The lint screen is clogged with a fine residue film
What separates it A visibly clean-looking lint screen can still be coated with a fabric-softener film that isn't visible lint but blocks airflow through the mesh just as effectively.
How to confirm Wash the screen with warm water and a soft brush, then hold it up to a light — if light doesn't pass through evenly, the film is still there.
- 3
Load is oversized or mixed with items of very different absorbency
What separates it Time increased on a specific load type (heavy towels, bedding, athletic wear) rather than across all laundry, and a smaller or more uniform load of the same items dries in normal time.
How to confirm Split the load or run a same-size, similar-fabric load as a controlled comparison against the normal drying time.
- 4
The moisture sensor bars are coated with residue
What separates it On Sensor Dry specifically (not Timed Dry) the cycle runs long because the sensor keeps reading the load as damp longer than it actually is; running the identical load on Timed Dry for a fixed time produces a normally dry result.
How to confirm Clean the sensor bars — usually inside the drum near the door — with the method the manual specifies; do not sand or scrub with anything abrasive enough to remove the sensing surface.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the increase happened gradually or suddenly — gradual points to airflow restriction building up, sudden points to a load, setting or single-component cause.
- Whether the same load size runs long on Timed Dry as well as Sensor Dry — if only Sensor Dry is affected, the sensor bars are the first suspect.
- How warm the exterior vent hood air feels compared to memory of when the dryer was new.
Clean the lint screen and check for a residue film
ReversibleWash with warm water if a film is visible or if light doesn't pass through evenly, then let it fully dry before reinstalling.
Inspect the full exhaust path to the exterior hood
ReversibleConfirm the flap moves freely and feel for strong exiting airflow during a cycle.
Run a controlled comparison load
ReversibleTime a medium load of similar, unmixed fabrics on both Timed Dry and Sensor Dry to isolate whether the sensor or the airflow is the affected component.
Clean the condenser coil on a heat-pump model, or clear/shorten a restricted duct on a vented model
ReversibleFollow the model's specific procedure for whichever applies.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- MED7230H*. Maytag dryer; confirm electric/gas model and complete suffix.
- Fuel — ELECTRIC (vented)
- ELECTRIC vented dryer on 240V. No heat with the drum turning is often a half-tripped double breaker; reset both halves first. Vent must be clear.
- Venting
- Clogged lint screen or blocked duct is the top cause of long drying/overheating.
- Features
- Extra Power option and Advanced Moisture Sensing; Wi-Fi on smart builds.
- Symptom boundary
- This record covers Maytag MED7230 electric dryer when it takes too long to dry clothes. A different symptom on the same hardware, or this symptom on a different Maytag product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Stop heated use if the cabinet, door or exterior vent area feels unusually hot — that is a safety condition, not a performance one.
- !A vent duct that cannot be cleared with a normal vacuum or brush kit, especially long or routed-through-wall installations, needs a professional dryer-vent cleaning service, not disassembly.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Maytag Product Help publishes this as "Long Dry Times - Dryer". The maker's own long-dry-time article: load size, vent restriction, lint screen and cycle selection. Read from the harvested leaf page, 2026-08-23. What that article does not carry is the model boundary — it is written for a product line, and MED7230H* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
Why is my Maytag MED7230 drying so slowly?+
Slow drying is airflow: clean the lint screen every load and clear the exhaust duct to the outside — a restricted vent traps moist air and drags out the cycle. Use the Extra Power option for thick loads, dry similar fabrics together, and avoid overloading. A total lack of heat is different (breaker or element), but slow drying is nearly always the vent.
Drying time has been getting worse for months.+
That gradual pattern points to a restricted exhaust vent building up over time, not a sudden component failure. Check the exterior vent hood flap movement and feel for airflow strength compared to when the dryer was new.
The dryer's lint screen looks clean but drying is still slow.+
A fabric-softener residue film can coat the mesh invisibly. Wash the screen with warm water and check whether light passes through evenly afterward — if not, the film is still restricting airflow.
Only Sensor Dry cycles run long, but Timed Dry works fine.+
That isolates the moisture sensor bars, not the airflow. Clean them using the method in the manual — they're usually just inside the drum near the door opening.
Does this answer apply to every Maytag model?+
No. It is scoped to MED7230H*. Maytag dryer; confirm electric/gas model and complete suffix.
What should I record before troubleshooting takes too long or clothes damp?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing takes too long, clothes damp. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop heated use for weak exterior airflow, excessive cabinet heat or burning odor.
