What the dryer is detecting
On these 2005-2016 platforms the control flags its own internal fault with F-01. The service documentation treats the machine control electronics as the corrective item.
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 failed main control.
- Possible A power disturbance that left the control in a faulted state.
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
- Confirms the control has power and that the fault returns after a reset.
- Replaces the machine control electronics if the fault persists.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| 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 the dryer until the control is checked; a failing control may not switch the motor and heat correctly.

Repair or replace?
A fault code alone rarely justifies replacing a dryer. Most F01 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.
