Maytag Error Code F5 E3: What It Means and How to Fix
Maytag error code F5 E3 means the moisture sensor circuit has failed. The dryer can’t detect moisture levels, so automatic dryness cycles stop working. The most common fix is replacing the sensor, but many cases resolve by simply reseating a loose connector or cleaning corrosion off the metal strips. With basic tools and a multimeter, most DIYers can fix it in under an hour.
First, Check the Obvious
Before pulling panels, a quick visual inspection often catches the real issue without any parts cost. Fabric softener buildup on the sensor strips, for example, creates a conductive film that tricks the dryer into reading moisture constantly, which triggers the error. The same happens when heavy lint coats the strips and insulates them.
Quick prep scan (run through these before disassembly):
– ☐ Dryer unplugged from wall outlet – power cord secured away from the work area.
– ☐ Lint filter removed and inspected – debris stuck behind the filter housing can interfere with sensor alignment.
– ☐ Connector at the sensor visually checked – push it firmly onto the pins; listen for a click that confirms full seating.
– ☐ Metal sensor strips inside the drum – look for heavy lint coating or gray/white crust (fabric softener residue).
– ☐ Model number noted – you’ll need it to verify sensor location and order the correct replacement part.
If any of these checks reveal a loose plug, dirty sensor, or shifted lint filter, fix that first. Often the error clears without replacing anything. If not, move on to the systematic electrical test.
Testing and Replacing the Sensor
Step 1: Access the Moisture Sensor
Remove the dryer’s top panel by releasing the spring clips at the front edge with a putty knife. Then remove the front panel – there are typically two screws at the bottom, and the door switch wire must be disconnected. The moisture sensor sits on a small plastic bracket inside the drum area, usually near the lint filter housing or on the rear bulkhead. Look for two metal strips with a two-wire connector.
Common mistake: Forgetting to unplug the door switch wire before pulling the front panel too far. Unplug it first to avoid tearing the wires.
Step 2: Test the Sensor with a Multimeter
Disconnect the sensor’s wire harness. Set your multimeter to resistance mode (200k or 2M range). Place one probe on each of the two metal strips – not on the wire terminals, but directly on the strips inside the drum. Measure the resistance.
| Sensor Condition | Typical Reading | Action |
|---|---|---|
| Good (clean, dry) | 50–500 kΩ (varies by model) | Clean sensor with fine sandpaper or a Scotch-Brite pad; re-test |
| Open circuit | Infinite (OL) | Replace sensor |
| Shorted circuit | 0 Ω or very low (<1 kΩ) | Replace sensor |
If the reading is within range but the error persists, the sensor may have a film of fabric softener or lint. Clean the strips gently until they’re shiny, then reconnect and test again. A pencil eraser can also work for light buildup – just avoid scratching the surface deeper.
Common mistake: Touching the metal strips with bare fingers. Skin oils alter the resistance reading. Wear gloves or clean the strips with isopropyl alcohol afterward.
Step 3: Replace the Sensor (If Needed)
If the sensor tests open, shorted, or cleaning doesn’t fix it:
– Remove the two screws holding the sensor bracket.
– Unplug the wire harness.
– Note which wire connects to which terminal if the connector isn’t keyed.
– Install the new sensor in the same orientation.
– Reconnect the harness, then reassemble the dryer in reverse order.
Step 4: Check the Wiring Harness (Before Calling a Pro)
If the new sensor still doesn’t clear the error, the problem may be the wiring between the sensor and the control board. Use your multimeter in continuity mode to check each wire in the harness. Place one probe on the sensor-side terminal and the other on the corresponding pin at the control board connector. No continuity means a broken wire or corroded pin – replace the harness or repair the break.
How to Confirm the Fix Worked
After reassembly, plug the dryer in and run a short timed dry cycle (5 minutes on high heat). If no error appears, switch to an automatic sensor cycle like “Sensor Dry” with a slightly damp towel inside. The dryer should shut off at the correct dryness level without triggering F5 E3. If the error returns during the sensor cycle, the control board may still be faulty.
Success signal: The dryer completes a full automatic cycle without stopping mid-cycle or flashing the error.
Failure signal: The code reappears within the first two minutes of a sensor cycle – stop and escalate.
When to Call a Pro
Replace the sensor and the error still shows? The issue may be deeper:
- Damaged wire harness – you’ve already checked continuity; if the harness looks melted or pinched, it’s time to replace it.
- Control board failure – uncommon but possible. Look for burn marks, bulging capacitors, or melted insulation on the board connector.
Stop and schedule a technician if:
– You see obvious burn damage on the control board.
– The harness has melted insulation near the board connector.
– You’ve verified continuity from sensor to board and the board still ignores a valid sensor signal.
A new control board typically runs $150–$250 plus labor – rarely worth the DIY risk.

Frequently Asked Questions
Can I keep using the dryer with error F5 E3?
Yes, but only on timed dry cycles. Automatic sensor cycles will not work correctly, and the error may reappear. Use timed dry until you fix the sensor.
Will unplugging the dryer clear F5 E3 temporarily?
Unplugging for 30 minutes can clear a transient glitch. If the sensor circuit is actually faulty, the error will return the next time you select an automatic cycle.
How much does a replacement moisture sensor cost?
$15–$40 for the part. Maytag sensors are widely available online or at appliance parts stores. Always verify the part number for your specific model.
What other error codes behave like this?
Similar moisture sensor circuit faults appear in Whirlpool family washers. For a parallel diagnostic approach on a washer, see our guide on how to diagnose f3 e1 error in whirlpool washing machine. The same test logic – sensor continuity and wiring checks – applies. Also, the common causes of f6 e2 error in whirlpool washing machines may help you identify similar sensor-related issues. And if you encounter a related fault on a washer, the understanding the f9e1 error code in whirlpool washers page provides nearly identical diagnostic steps.
I don’t have a multimeter – what now?
You can still clean the sensor and reseat the connector. Without a multimeter you can’t confirm electrical function. In that case, replace the sensor as a first step – it’s inexpensive and the most common cause. A $20 part is a safe bet.
