■

Has a household fuse blown, or has a circuit breaker 
tripped? 
There may be 2 fuses or circuit breakers for the dryer. Check 
that both fuses are intact and tight, or that both circuit 
breakers have not tripped. Replace the fuse or reset the 
circuit breaker. If the problem continues, call an electrician.

■

Is the correct power supply available? 
Electric dryers require 240-volt power supply. Check with a 
qualified electrician.

■

Was a regular fuse used? 
Use a time-delay fuse.

■

■

Was the Start button firmly pressed? 
Press and hold for 1 second.

■

Has a household fuse blown, or has a circuit breaker 
tripped?
The drum may be turning, but you may not have heat. Electric 
dryers use 2 fuses or circuit breakers. Replace the fuse or 
reset the circuit breaker. If the problem continues, call an 
electrician.

■

Has the dryer had a period of non-use? 
If the dryer hasn’t been used for a while, there may be a 
thumping sound during the first few minutes of operation. 

■

Is a coin, button, or paper clip caught between the drum 
and front or rear of the dryer? 
Check the front and rear edges of the drum for small objects. 
Clean out pockets before laundering.

■

Are the four legs installed, and is the dryer level front to 
back and side to side? 
The dryer may vibrate if not properly installed. See 
“Installation Instructions.”

■

Is the clothing knotted or balled up? 
When balled up, the load will bounce, causing the dryer to 
vibrate. Separate the load items and restart the dryer.

■

“PF” (power failure), check the following:
Was the drying cycle interrupted by a power failure?
Press and hold START to restart the dryer.

■

“F-” Variable (F-01, F-22, F-23, F-26) service codes (the 
display alternately flashes "F-" and then the error code 
number):
Call for service.

■

Is the lint screen clogged with lint? 
Lint screen should be cleaned before each load. 

■

Is the exhaust vent or outside exhaust hood clogged with 
lint, restricting air movement? 
Run the dryer for 5-10 minutes. Hold your hand under the 
outside exhaust hood to check air movement. If you do not 
feel air movement, clean exhaust system of lint or replace 
exhaust vent with heavy metal or flexible metal vent. See 
“Venting Requirements.” 

■

Are fabric softener sheets blocking the grille? 
Use only one fabric softener sheet, and use it only once.

■

Is the exhaust vent the correct length? 
Check that the exhaust vent is not too long or has too many 
turns. Long venting will increase drying times. See “Plan Vent 
System.”  

■

Is the exhaust vent diameter the correct size? 
Use 4" (10.2 cm) diameter vent material.

■

Is the dryer located in a room with temperature below
45ºF (7ºC)? 
Proper operation of dryer cycles requires temperatures above 
45ºF (7ºC).
