How to clean moisture sensor on Maytag dryer?
On a Maytag MDE9806AYW dual-fuel dryer, we clean the moisture sensor by gently scrubbing the two metal sensor bars inside the drum (near the lint filter housing) with rubbing alcohol, then running a short timed-dry cycle to confirm the Sensor Dry cycles are reading correctly.
What you need
- Isopropyl (rubbing) alcohol (70% or higher)
- Soft cloth or cotton swabs
- Mild dish soap and warm water (for general drum wipe-down)
- Flashlight
- Optional: fine non-scratch pad (only if residue is stubborn)
Step-by-step: cleaning the moisture sensor
- Power off the dryer: turn it off and unplug it (or switch off the breaker).
- Locate the sensor bars: look inside the drum opening; most Maytag dryers use two parallel metal strips mounted on the front bulkhead near the lint screen area.
- Clean the bars:
- Dampen a cloth with isopropyl alcohol.
- Rub each bar firmly from end to end to remove dryer sheet wax, fabric softener residue, and detergent film.
- Remove remaining film (if needed): wipe with a cloth dampened with warm soapy water, then wipe again with clean water.
- Dry completely: let the bars air-dry for a minute.
- Test Sensor Dry: run a small load on a Sensor Dry cycle and confirm the cycle does not end too early.
If Sensor Dry still ends too soon
Residue is the most common cause, but airflow problems can mimic a bad sensor reading.
- Clean the lint screen and check for tears or warping; replace it if it does not fit tightly (see dryer lint filter WP33001808)
- Check the exhaust vent for crushing, kinks, or heavy lint buildup
- Avoid dryer sheets for a few loads to prevent re-coating the sensor bars
- If the dryer overheats or shuts off, test safety devices; a blown fuse often points to restricted airflow (see dryer thermal fuse, 243-degree f WP307473)
Quick reference
| Symptom | Most common cause | What to do first |
|---|---|---|
| Sensor Dry ends in 5 to 10 minutes | Sensor bars coated | Clean with isopropyl alcohol |
| Clothes still damp, cycle runs long | Vent restriction | Clear vent and outside hood |
| Dryer stops, no heat, or intermittent heat | Overheat protection tripped | Check airflow, then test fuse/thermostat |
Why it matters
The moisture sensor controls automatic dry time. When the bars are coated, the dryer “thinks” clothes are dry and can shut off early, causing damp loads and repeat cycles.

What is the capacity of the Maytag MDE9806AYW?
The Maytag MDE9806AYW is a full-size 27-inch dryer; dryers in this Maytag size class are typically about 6.0 to 7.0 cu. ft. drum capacity. Use that range for load planning, then match parts and features by model number when servicing the dryer.
What “capacity” means on a dryer
Dryer capacity is the drum volume (cubic feet). It is not the exterior width. Capacity affects tumbling space, airflow through the load, and how evenly items dry.
- More drum space helps bulky items tumble and dry evenly
- Overloading restricts airflow and increases dry time
- Underloading can cause tangling on some cycles
- Poor venting can make any capacity dry like a smaller dryer
Quick load guide for a 6.0 to 7.0 cu. ft. dryer
| Load type | Typical fit | Best practice |
|---|---|---|
| Mixed everyday load | Yes | Fill loosely; keep items below the top of the drum |
| Towels/jeans | Yes | Dry similar fabrics together for even results |
| Queen or king comforter | Sometimes | Use low heat; pause to re-fluff and reposition |
If loads are “too big” because drying is slow
Slow drying is usually an airflow issue, not a capacity issue. Start with these checks:
- Clean the lint screen every load; replace a torn or warped screen with the dryer lint filter WP33001808
- Inspect the vent hose for kinks, crushing, or heavy lint buildup
- Confirm the outside vent hood opens fully and is not blocked
- If the dryer runs but stops heating, check the safety cutoff; a common item is the dryer thermal fuse, 243-degree f WP307473
Why it matters
Using the right capacity target prevents chronic overloading, which reduces strain on the blower system, heater, and drum support components. Good airflow also improves drying performance and helps prevent overheating.

How do I find the model number on my MDE9806AYW?
The model number for your Maytag dual-fuel dryer is printed on the appliance’s model and serial tag. On most Maytag dryers like model MDE9806AYW, that tag is located around the door opening (on the door frame) or on the inside of the dryer door.
Where to look on a Maytag dryer
Check these common locations in this order:
- Open the dryer door and look on the door frame near the latch area
- Look along the inside edge of the dryer door itself
- Check the front panel just inside the door opening
- If you have a pedestal or tight install, use a flashlight to read the label clearly
What the label should show
You are looking for a sticker or metal plate that includes:
- Model number (for example, MDE9806AYW)
- Serial number (used to identify production run and date)
- Electrical and fuel information (helpful for troubleshooting and safe service)
| Item on tag | What we use it for |
|---|---|
| Model number | Matching the correct parts diagram and part fit |
| Serial number | Identifying exact production variation |
| Voltage/fuel info | Confirming correct electrical and gas setup |
Why it matters
Using the exact model number prevents ordering the wrong dryer parts. Even small differences in a Maytag dryer series can change the fit of common replacements like a thermal fuse, heating component, or lint filter.
If your tag is missing or unreadable, match parts by comparing your dryer’s components to the diagrams and known replacements listed for MDE9806AYW, such as the dryer lint filter WP33001808.
