Error code F 1 is on and the dryer wont start. Does anyone know what the problem is?
Answer Hello Hank. F-01 flashes when there is a primary control failure. Replace the machine
AF flashes when drying. checked lint filter, cleaned sheetmetal housing, blower wheel, and wall vent for clogs. dryer hot, clothes wet. sometimes "sensing" stays on for awhile. F29 code once in diagnostic, then F25 most recently but signs still pointing to air flow problems. at a loss before starting with each sensor replacement. your help is of great value and is much appreciated. thank you in advance.
Answer DIAGNOSTIC: Displaying Inlet Air Flow
Used to display the air flow value at the inlet of the heater box being measured by
the machine control.
After all saved fault codes have been displayed, press the Wrinkle Shield button to
activate air flow detection. A 30 or 50 second countdown timer will start and the
dryer will turn on.
? If the dryer is cold, the countdown will start at 50 seconds.
NOTE: If the dryer is extremely cold (less than 40°F [4.4°C]) the air flow may
not be detected properly, and “--” will be displayed.
? If the dryer is hot, the countdown timer will start at 30 seconds (cool down
period) followed by an additional 50 second countdown.
A Dryness modifier LED will also be illuminated to indicate the air flow range
corresponding to the number displayed.
¦ The More LED will be illuminated for air flow readings above 40 cfm.
¦ The Normal LED will be illuminated for air flow readings between 29 and 40 cfm.
¦ The Less LED will be illuminated for air flow readings less than 29 cfm.
? If air flow value is low, check to make sure the lint screen is clean, the door
seal is in place and the vent is not obstructed.
Dryer does not heat. I replaced the heating element and it still does not heat.
You will want to do a continuity test on the thermal fuse 279973 and the high limit thermostat to make sure that they have continuity. If they do not have continuity replace whichever part does not have continuity. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
What does the dryer thermister do?
Answer Hello Jean-ann. It is used to sense the temperature of the air coming out of the unit.
The dryer blinks AF and has a clicking noise then if you push the pause button then start again it sometimes works. The dryer gets hot but does not blow the hot air out of the vent. I have checked the vents and they are clear but when I put my hand against the back of the dryer I dont feel any air coming out when its running., ALso the timer sometimes doesnt go down or will go from 30 mins to 45 mins.
Answer Hello Jeff. The pulley 8544739 for the blower wheel may be off. Unplug dryer or disconnect the power.
Remove front panel and lint chute. Remove the blower pulley completely from the bearing shaft (if not
already disengaged). Apply a coating of medium strength
thread lock 4210460 to the entire length of threads
on the blower shaft. Use a crescent wrench or 1 1/8” open end
wrench on the pulley nut and a ½ square
drive ratchet to hold the blower wheel and
tighten. Note: If a torque wrench is available, the torque
specification is 120 in. lbs. or 10 ft. lbs. Install belt and check.
Note: The belt should not touch the tab on the
blower housing. Install all panels and screws. Plug in dryer or connect power. Operate the dryer and check operation.
i have replaced the motor ;push to start switch buzzer switch thedryer just makes huming noise ican reach inside spin the drum and the dryer takes off and runs what would keep the dryer from running
Answer Dean, Are you sure you have 220 VAC at the outlet, and at the terminal block on the back of the dryer. Check and make sure all the terminals and connections on the terminal block are good and tight. If you're sure you have everything installed and wired correctly, you'll need to by pass the door switch and check for 120 VAC across the blue and white wires at the motor switch when the start button is activated. You may have a faulty contact in the timer, or loose connection causing low voltage to the motor.
