F3E2: Exhaust thermistor shorted
- Brand
- Whirlpool
- Appliance
- Electric dryer, Gas dryer
- Code
- F3E2
- Documented meaning
- Exhaust thermistor shorted
- Applies to
- 324 Whirlpool models on 14 platforms
- Can you keep using it?
- No — stop and have it checked
F3E2 on older platforms means the exhaust (outlet air) temperature sensor reads as shorted, a value that would mean an implausibly high temperature.
What the dryer is detecting
The control reads the exhaust thermistor to regulate heat. On these platforms F3E2 is set when the reading corresponds to a temperature far above anything the dryer should reach, which the control treats as a shorted sensor or circuit rather than a real temperature.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A shorted exhaust thermistor.
- Possible Pinched or chafed sensor wiring touching metal or another wire.
- Possible A fault in the sensing circuit of the main control.
Safe checks you can make
- Turn the dryer off at the breaker (or unplug it) for about one minute, restore power and start a new cycle to see whether the code comes back right away.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Reads the temperature sensor values in the service diagnostic mode and compares them with the room temperature.
- Checks the sensor connector at the main control and the sensor's own connection for a loose or damaged terminal.
- Tests the sensor and its circuit before deciding whether the sensor, the harness or the main control is at fault.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dryer exhaust thermistor replacement | $180–$290 | Light |
| Dryer main control board replacement | $280–$640 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Stop using heated cycles until the sensor is checked. The control has lost a reliable temperature reading for the exhaust air.

F3E2: Moisture sensor fault
- Brand
- Whirlpool
- Appliance
- Electric dryer, Gas dryer
- Code
- F3E2
- Documented meaning
- Moisture sensor fault
- Applies to
- 163 Whirlpool models on 24 platforms
- Can you keep using it?
- With caution
F3E2 on 2013 and newer platforms means the moisture sensor strip in the drum reads as open or shorted.
What the dryer is detecting
Two metal strips inside the drum touch the tumbling clothes, and the control reads how easily current passes between them to judge dryness. F3E2 is set when that circuit looks permanently open or permanently shorted. On most of these platforms the code is shown only in the service diagnostic menu.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A moisture sensor strip or its wiring that is open or shorted.
- Possible A loose connection between the sensor strips and the main control.
- Possible A metal object (coin, hairpin) lodged across the strips, causing a false short.
- Possible A sensing-circuit fault on the main control.
Safe checks you can make
- Wipe the two metal moisture-sensing strips inside the drum (usually near the lint screen opening) with a soft cloth and a little rubbing alcohol to remove fabric-softener film.
- Check the drum and the lint screen opening for coins, pins or other small metal objects.
- On many models this code is stored only for the service diagnostic menu, so the dryer may still run normally; if you see it, note it for the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Runs the moisture sensor test in the service diagnostics while bridging the strips with a damp cloth.
- Inspects the sensor strip wiring and its connection at the main control.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dryer moisture sensor bar repair | $180–$310 | Light |
| Dryer main control board replacement | $280–$640 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The dryer can usually still run, but automatic (sensor) cycles may end too early or run too long. Timed dry is a reasonable temporary workaround; watch the first loads.

F3E2: Moisture sensor fault
- Brand
- Whirlpool
- Appliance
- Heat-pump dryer
- Code
- F3E2
- Documented meaning
- Moisture sensor fault
- Applies to
- 4 Whirlpool models on 2 platforms
- Can you keep using it?
- With caution
F3E2 on heat pump dryers means the moisture sensor strip reads as open or shorted. It appears only in the service diagnostic mode.
What the dryer is detecting
Metal strips in the drum let the control judge dryness by how easily current passes through wet clothes. A circuit that stays open or shorted is flagged in the service diagnostics.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented An open or shorted moisture sensor strip or wiring.
- Possible Residue or a metal object on the strips.
Safe checks you can make
- Wipe the two metal moisture-sensing strips inside the drum (usually near the lint screen opening) with a soft cloth and a little rubbing alcohol to remove fabric-softener film.
- On many models this code is stored only for the service diagnostic menu, so the dryer may still run normally; if you see it, note it for the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Runs the moisture sensor test in the service diagnostics.
- Inspects the strip wiring and connections.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dryer moisture sensor bar repair | $180–$310 | Light |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The dryer usually still runs; automatic cycles may be inaccurate, so watch loads or use a timed cycle.

Repair or replace?
A fault code alone rarely justifies replacing a dryer. Most F3E2 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 12–14-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
