F3 E3 on a Maytag dryer means the moisture sensor has failed or is coated with residue. The sensor bars are two metal strips on the front bulkhead inside the drum. Fabric softener and dryer sheet residue coats these bars over time and blocks the low-voltage signal.
This code almost always comes down to dryer sheet wax, and I've scrubbed those sensor bars on probably a dozen Maytag dryers in the last six months alone. If you ignore it, you'll end up running the machine on Timed Dry forever, which wears out your heating element way faster than normal. Most people fix this themselves in 10 minutes. The ones who can't are usually dealing with a dead sensor or a loose wire behind the front panel.

What Does the F3 E3 Code Mean?
While Maytag builds these sensors to last, they rely on a very weak electrical current passing between two metal strips. If that circuit's broken by a loose wire or a heavy layer of fabric softener, the computer throws the F3 E3 flag. I always check the harness connections behind the front panel if cleaning the bars doesn't do the trick.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Sensor bars coated with fabric softener or dryer sheet residue40%
Sensor wiring harness fault or broken connector24%
Control board input circuit for moisture sensor failed22%
Moisture sensor assembly failure14%
Symptoms You May Notice
F3 E3 flashes on the display within the first few minutes of an auto-sensing cycle, sometimes before the drum even finishes its first full rotation.
The dryer quits after 8-12 minutes and your laundry's still dripping wet when you pull it out.
Auto-sensing cycles never finish right, but if you switch to Timed Dry it runs the whole time without complaint.
Clothes coming out overdried and stiff because you've been adding extra time manually to compensate for the early shutoffs.
The sensor cycle just maxes out every single load like the machine thinks your clothes are permanently wet.
Can you reset a Maytag dryer to clear the F3 E3 code?
Clear the code by unplugging the unit for one full minute. When you power it back up, don't just hit Start on an auto cycle. Run a 20-minute Timed Dry first. This forces the motor to spin and clears the logic board's memory before it tries to read those moisture sensors again. After that cycle finishes, try a small load on Normal and see if the sensor picks it up correctly.

Frequently Asked Questions
Why does using dryer sheets cause F3 E3 on Maytag dryers?
Dryer sheets are basically thin fabric coated in waxy fat and fragrance. When they heat up in the drum, that fat melts and coats everything inside, including the sensor bars. Over dozens of loads it builds up into an insulating layer that the low-voltage signal just can't punch through anymore. So the dryer thinks your clothes are dry when they're still soaking wet. It's the most common reason I get called out for Maytag dryers that stop early, honestly, and it's almost always a five-minute fix once you know what you're looking for.
Can I use my Maytag dryer while it shows F3 E3?
Yeah, you can keep using it on Timed Dry while you wait for parts or get around to cleaning the bars. In timed mode, the machine just counts down the minutes and ignores those sensor bars completely. Just don't set the timer too long, because the dryer won't automatically shut off if the clothes get dry early. Overdrying is rough on fabrics and can shrink stuff, so set it for a little less time than you think you need and check the load.
How often should I clean the moisture sensor bars to prevent F3 E3?
For a typical family doing five loads a week with dryer sheets, every three months is a good rule. I tell people to tie it to changing the clocks for daylight savings. That's twice a year and it's easy to remember. But honestly, if you notice your Normal cycle starting to leave clothes a little damp and you haven't had the F3 E3 code yet, that's your early warning. Go wipe those bars down right then before the code pops.
Is the F3 E3 sensor part the same as on a Whirlpool dryer?
They're identical. Whirlpool bought Maytag years ago and most modern Maytag dryers are built on the Whirlpool vertical modular platform. The sensor bars, the wiring harness, and the error code logic are all the same across both brands. Part number WP8566574 works on both. If you find a repair video for a Whirlpool F3 E3, it'll walk you through the exact same steps that work on your Maytag. Just ignore the brand name on the front of the machine.
The code cleared after cleaning but came back in a week. What's going on?
If cleaning worked briefly and then the code came back fast, check your lint screen and vent ducting for a blockage. A clogged vent makes the dryer run way too hot, which bakes that dryer sheet residue onto the bars much faster than normal. Also, look closely at the wire connections on the back of the sensor. Sometimes the wires are barely touching the connector pins, so the dryer works fine until it heats up and the connection fails. That's an intermittent fault that's way harder to track down than a simple dirty sensor.
How much does it cost to fix F3 E3 on a Maytag dryer?
If it's just dirty sensor bars, it costs you maybe $3 in isopropyl alcohol and 10 minutes of your time. The WP8566574 sensor assembly runs about $20-35 online, and it's a pretty straightforward swap. If the main control board's shot, that's a different story, usually $150-250 for the part alone, plus labor if you're not doing it yourself. Most F3 E3 calls don't get to board replacement. I'd say 8 out of 10 are solved by cleaning or a new sensor, so start cheap and work your way up.
